Answer:
This doesn't make sense.
Step-by-step explanation:
If the question was "A mother bear and her cub catch fish from a river. The cub catches 10 fish and the mother bear catches 5 times as many as the cub. How many fish did the cub catch?" then the answer would be, The mother bear caught 50 fish.
This is because if the cub caught 10, and the mother caught 5 times that amount, the mother caught 5 x 10 fish. 5 x 10 = 50.
Explain how to find the value of a line's y-intercept using its point-slope equation.
Answer:
Given the point-slope form of a line, y = mx + b, to get the y-intercept of a line, you first have to solve for b by setting x = 0. This gives you the b-value of y = 0 + b = b. We see that b is the y-intercept.
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
The point-slope form of a line looks like
y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex])
The number that is the place of the 'm' is the slope.
For example:
If we had the equation
y - 3 = 12(x +4)
The slope would be 12.

For each graph below, state whether it represents a function. Graph 1 Graph 2 Graph 3 24 . 864 7 21 6 & -2 4- -6- Function? Yes O No Graph 4 Yes ONo Graph 5 Yes O No Graph 6 60 Function? Yes O No Yes ONo Yes O No
Using the vertical line test, there are only two graphs that represent functions (graph function): graph, 1 and graph 6.
A graph function is a graph that represents a function on a coordinate plane, which means that every point on the graph fulfills the function equation. In a graph function, an x corresponds to only one y.
If we want to know whether a graph represents a function or not, we can perform a vertical line test. In this test, we can drag a vertical line from left to right on the graph. If the vertical line intersects with the graph at one point at a time, then it's a function.
Otherwise, if the vertical line intersects with the graph at two or more points at a time, then it's not a function. It could happen when an x value gives two or more y values (1 input results in multiple outputs), which means the graph is not a function.
Now we take a look at the given picture.
Graph 1: when we drag a vertical line from left to right on the graph, it intersects with the graph at one point at a time. So yes, the graph represents a function.
Graph 2: when we drag a vertical line from left to right on the graph, it intersects with the graph at two points. So no, the graph doesn't represent a function.
Graph 3: when we drag a vertical line from left to right on the graph, it intersects with the graph at one point at first. But later on, it crosses two points in the graph. So no, the graph doesn't represent a function.
Graph 4: when we drag a vertical line from left to right on the graph, it intersects with the graph at two points. So no, the graph doesn't represent a function.
Graph 5: when we drag a vertical line from left to right on the graph, it also intersects with the graph at two points. So no, the graph doesn't represent a function.
Graph 6: when we drag a vertical line from left to right on the graph, it intersects with the graph at one point at a time. So yes, the graph represents a function.
So there are only two graphs that represent functions: graph, 1 and graph 6 since the other graphs fail the vertical line test.

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term.
Nature of Roots of the Quadratic Equation
The symbols alpha () and beta () are typically used to denote a quadratic equation's roots. Here, we'll learn more about how to identify a quadratic equation's nature without locating the equation's roots. Additionally, look at the formulas for calculating the product and sum of the equation's roots.
Without actually locating the roots (, ) of the equation, the nature of the roots of a quadratic equation can be determined. By using the discriminant value, which is a component of the quadratic equation solution formula, this is made achievable. The discriminant of a quadratic equation is denoted as "D" and has the value b2 - 4ac. Using the discriminatory value as a basis, the nature of the roots of the quadratic equation can be predicted.
Discriminant: D = b2 - 4ac
D > 0, the roots are real and distinct
D = 0, the roots are real and equal.
D < 0, the roots do not exist or the roots are imaginary.
From the given quadratic equation, we can observe that:
a = 5
b = -4
c = 5
On finding discriminant, we get:
D = b² - 4ac
D = (-4)² - (4 × 5 × 5)
D = 16 - 100
D = -84
We can notice that, D(-84) < 0, which means the roots are unreal. Therefore, no roots exist!

Taking the square root of a number is equivalent to putting that number to the power of 1/2.
Step-by-step explanation:
x^(a/b)
means
[tex] \sqrt[b]{ {x}^{a} } [/tex]
the numerator of the exponent is the actual "to the power of" factor.
the denominator defines the degree of the root to be taken.
as any integer number is also a fraction like
6 = 6/1
this applies to any form of rational numbers like
x^0.25 = x^(25/100) = x^(1/4) =
[tex] \sqrt[4]{ {x}^{1} } = \sqrt[4]{x} [/tex]
with irrational numbers as exponents this gets trickier, as with infinite numbers without a pattern after the decimal point we have a problem to precisely specify the degree of the root, as we also have a problem to specify the irrational number itself.
we try to find the origin of the irrational number (like a square root)
[tex] {x}^{ \sqrt{3} } [/tex]
or
[tex] \sqrt[ \sqrt{3} ]{ {x}^{2} } = {x}^{2 \div \sqrt{3} } [/tex]

Describe conjecture.A conjecture turns into a theorem when it is rigorously proven. A conjecture is not merely a tool for professional mathematicians; it is an essential step in problem-solving. It is extremely uncommon for a problem's solution to be immediately obvious while tackling problems on a daily basis. Instead, establishing a conjecture about the answer and then proving it through evidence are steps in the problem-solving process that include reviewing cases and the problem's structure. When one observes a pattern that holds true in numerous instances, hypotheses start to form. A pattern may be true in many instances, but that does not guarantee that it will be true in all instances. For a mathematical observation to be fully accepted, conjectures must be proven.

How do you know if the y-intercept is positive or negative?
A positive y-intercept means that the line crosses the y-axis above the origin, and a negative y-intercept means that the line crosses below the origin. Arbitrary lines can be defined simply by changing the values of m and b.
Slope Intercept:
The slope intercept of the straight line is used to find the equation of the straight line. The slope intercept formula requires knowing the slope of the line and the intersection of the line with the y-axis. Consider a line with slope 'm' and y-intercept 'b'. The slope-intercept shape formula for a straight line with slopes 'm' and 'b' as y-intercept is given as y = mx + b.
Positive Intercept:
A positive slope refers to a line that is slanted and slopes upward when viewed from left to right. The positive slope of a straight line can be calculated using the formula m = (y2 - y1)/(x2 - x1) = Tanθ = f'(x) = dy/dx. A positive slope means that the two quantities represented along the two axes of the coordinate system increase or decrease simultaneously. A line with a positive slope is a positive value for the ratio of climb to run. A straight line with a positive slope makes an acute angle with the positive x-axis.
Positive slope (m) = +slope/run = +Δy/Δx
Negative Intercept:
Negative slope means that the coordinates of the two given points are negatively related. A line with a negative slope has m < 0, and the angle θ it makes with the positive x-axis is obtuse θ, such that 90° < θ < 180°. The slope-to-run ratio of the negative slope line is negative. where slope is the change in y value, denoted by Δy, and run is the change in x value, denoted by Δx.

D.Y-2 = 12(x - 1)
The equation of the line would be y - 20 = 12(x - 1).
Option (C) is correct.
What is the slope-point form of the line?
For the line having slope "m" and the point (x1, y1) the equation of the line passing through the point (x1, y1) having slope 'm' would be
y - y1 = m(x - x1)
Let's suppose on the y-axis there will be a number of copies sold and on the x-axis, there will be a number of days.
On day 1, he sold 20 copies so point would be (1, 20)
On day 2, he sold 32 copies so point would be (2, 32)
Slope of the line = (y2 - y1)/(x2 - x1)
= (32 - 20)/(2 - 1)
m = 12
By using the slope-point form of the line,
y - y1 = m(x - x1)
y - 20 = 12(x - 1)
Hence, the equation of the line would be y - 20 = 12(x - 1).

The plane intersects the paraboloid in an ellipse. Find the points on this ellipse that are nearest to and farthest from the origin. Point farthest away occurs at.
The point on the ellipse that is farthest from the origin will be the point that is closest to one of the foci.
To find the points on the ellipse that are nearest to and farthest from the origin, we need to consider the equation of the paraboloid and the equation of the ellipse.
The equation of a paraboloid is given by:
[tex]z = ax^2 + by^2 + c[/tex]
where a, b, and c are constants.
The equation of an ellipse is given by:
[tex](\frac{x}{a})^2 + (\frac{y}{b})^2 = 1[/tex]
where a and b are the semi-major and semi-minor axes of the ellipse, respectively.
If the plane intersects the paraboloid in an ellipse, then the equations of the paraboloid and the ellipse must be equal at the points of intersection. Therefore, we can set the equation of the paraboloid equal to the equation of the ellipse and solve for the x and y values.
[tex]z = ax^2 + by^2 + c[/tex]
[tex](\frac{x}{a})^2 + (\frac{y}{b})^2 = 1[/tex]
Substituting the equation of the paraboloid into the equation of the ellipse, we get:
[tex](\frac{x}{a})^2 + (\frac{y}{b})^2+c = 1[/tex]
We can then solve this equation for the values of x and y that correspond to the points on the ellipse that are nearest to and farthest from the origin.
The point farthest away from the origin occurs at the point on the ellipse that is farthest from the center, which is called the "foci" of the ellipse. The distance from the center of the ellipse to the foci is called the "eccentricity" of the ellipse. The eccentricity is denoted by the letter "e" and is calculated using the following formula:
[tex]e = \frac{\sqrt{(a^2 - b^2)}}{a}[/tex]
where a and b are the semi-major and semi-minor axes of the ellipse, respectively.
Therefore, to find the point on the ellipse that is farthest from the origin, we need to calculate the eccentricity of the ellipse and then use this value to determine the location of the foci. The point on the ellipse that is farthest from the origin will be the point that is closest to one of the foci.

How do you work out 15x15?
The product is 225.
What is multiplication?Augmentation is an activity that addresses the fundamental thought of rehashed expansion of a similar number. The numbers that are multiplied are referred to as the factors, and the result that is produced when two or more numbers are multiplied together is referred to as the product of those numbers. Repeated addition of the same number can be made easier by using multiplication.
Given 15 x 15
the product can be done in many ways,
like add 15times 15 we get the answer,
or 15 is written as 10 + 5
so (10 + 5) x 15
10 x 15 + 5 x 15
150 + 75 = 225
Therefore, 15 x 15 is 225

What is a Mapping Diagram?
A mapping diagram is an image of two circles which shows two values corresponding to each other, such that one is the input value to the function and the other is the output value.
Given ordered pairs :
(- 1, 0), (0, 3), (3, - 1), (9, 9)
Domain and range from given ordered pairs.
Domain - means x - axis
Range - means y-axis
Now, take out domain and range like that,
Domain of the function : (-1, 0, 3, 9) [ input values]
Range of the function : (0, 3, -1, 9) [ output values]
Now, we need to determine the value of function f(3).
It means 3 is input value in f(3) so the output value at 3 is,
f(3) = -1
Hence, the value of function f(3) is -1.

What will be the location of point ′ F ′ if the triangle wa dilated by a cale factor of 3
If the coordinates of point F are (x,y), then the coordinates of point F' after the dilation will be (3x, 3y).
To find the location of point F' after the triangle is dilated by a scale factor of 3, you need to multiply the coordinates of point F by the scale factor.
For example, if the coordinates of point F are (x,y), then the coordinates of point F' after the dilation will be (3x, 3y).
It's important to note that the dilation will change the size of the triangle, but not its shape. The angles of the triangle will remain the same, and the ratios of the side lengths will also remain the same.
If you have a specific triangle and the coordinates of point F, I can provide more detailed guidance on finding the coordinates of point F' after the dilation.
∴ If the coordinates of point F are (x,y), then the coordinates of point F' after the dilation will be (3x, 3y).
