Calculate the slope between the points: (4, -9) and (5, 1)
a
m=10
b
m=1/10
с
m=-10
d
m=-1/10
Answer:
The answer is A- m=10
Step-by-step explanation:
The way to find slope is known as "Rise over Run" meaning the increase of Y over the increase of X. The increase of Y is 10 because 1 - (-9) = 10. The increase of X is 1 because 5 - 4 = 1. 10 over 1, or 10 / 1, equals 10.
What is the probability of spinning a C?
Answer: 37.5%
Step-by-step explanation: Since there are 3 spaces for C it would be 3/8 for the amount of C's in all of the letters.
3/8 = 0.375 = 37.5%
Hope this helps!
The probability of spinning C will be 3/8 or 0375.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
The spinner has eight equal section. And the 8 sections are marked as A, B, B, B, A, C, C, and C.
Then the total number of the event will be
Total event = 8 {A, B, B, B, A, C, C, C.}
Then the probability of spinning C will be
The favorable event will be
Favorable event = 3 {C, C, C}
P = 3 / 8
P = 0.375
The probability of spinning C will be 3/8 or 0375.

12x + 8y = 24 Convert from standard form to slope-intercept form.
The required equation is y = -(3/2)x + 3 in slope-intercept form.
What is the standard form of linear equations?A linear equation is written in the standard form as Ax + By = C, where A, B, and C are integers and x and y are variables.
For example, 8x + 2y = 7 is the standard form of a linear equation in two variables.
The equation is given in the question, as follows:
12x + 8y = 24
Isolate the variable of y for the above equation,
8y = - 12x + 24
Divided both sides by 8 into the equation,
y = - (12x)/8 + (24)/8
y = -(3/2)x + 3
This equation is in slope-intercept form.

The diagram below shows y as a functional of x, True or False?
A)True
B)False
Answer:
False
Step-by-step explanation:
A function can't have 2 y-intercepts so y is not a function of x
Answer:
I believe it is A.
step-by-step explanation:
Because on the grid it is the Y corrdinate and the X coordinate so I belive it id True.

The equation of a line is y = -3x – 2. What are the slope and the y-intercept of the line?
A.
slope = -3 and y-intercept = 2
B.
slope = 3 and y-intercept = -2
C.
slope = 3 and y-intercept = 2
D.
slope = -3 and y-intercept = -2
The slope of the line is - 3 and the y - intercept of the line is - 2.
What is Equation of line?The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The equation of line is,
⇒ y = - 3x - 2
We know that;
The slope - intercept form of the equation of line is,
⇒ y = mx + b
Where, m is slope and b is y - intercept.
So, By comparing we get;
The slope (m) of the line = - 3
And, the y - intercept of the line = - 2.

Given problem:
What is the value of x = ?
Solution:
Angle on a straight line is 180°
Sum of angles in a triangle = 180°
Now to solve the problem, we need to find the two internal angles first;
For the first one;
let us say it is y;
163 + y = 180
y = 180 - 163 = 17°
For the second, assume it is z;
69 + z = 180
z = 180 -69 = 111°
The sum of the internal angles of the triangle;
y + z + 2x = 180
17 + 111 + 2x = 180
2x = 180 - 128
2x = 52
x = [tex]\frac{52}{2}[/tex] = 26
The value of x is 26
Write the slope-intercept form of the equation of the line described.
Through (-2, -1) and parallel to y=-2x-1
Answer:
y= -2x -5
Step-by-step explanation:
Slope-intercept form:
y= mx +c, where m is the slope and c is the y-intercept.
Parallel lines have the same slope.
Thus, to find the value of the slope of the line, we have to find the slope of the given line.
y= -2x -1
Since the coefficient of x is -2 and the equation is already in slope-intercept form, the slope of the given line is -2.
Substitute m= -2 into the equation:
y= -2x +c
To find the value of c, substitute a pair of coordinates.
When x= -2, y= -1,
-1= -2(-2) +c
-1= 4 +c
c= -1 -4 (-4 on both sides)
c= -5
Thus, the equation of the line is y= -2x -5.

what is the cost price of an article which when sold at Rs 10260 gives a profit of 20%?
Answer:
8208 Rs
Step-by-step explanation:
Rs: 10260
Profit 20%
10260 * 0.20 * 100% = 2052 Rs
10260 Rs - 2052 Rs = cost of product to be produced
CP: Rs 10260
Profit: 20%
Solution: 20% off 10260 is equal to (20 x 20) / 100 = 2052. So if you buy an item at $10260 with 20% discounts, you will pay $8208 and get 2052 cashback rewards
