Answer:
Step-by-step explanation:
When given a point and a slope, the best equation to use is the point-slope formula, y - k = m(x - h)
which here becomes:
y - 0 = m(x + 1), or y = (-2/3)(x + 1), or y = (-2/3)x - 2/3
If you want this in standard form, first clear the fractions by multiplying all terms by 3: 3y = -2x - 2
Now add 2x to both sides, obtaining: 2x + 3y = -2 (in "standard form."

On solving the provided question, we can say that, 16 square units make up the area of a circle with a radius of 4 units.
what is radius?The length of a circle or sphere, in more contemporary use, is the same as its radius in classical geometry, which is one of the line segments from its center to its circumference. The Latin word radius, which also refers to the spokes of a wagon wheel, gave rise to the term. Through the center of the circle, a straight line defines the diameter. Half of the diameter is the radius. End in the circle's center after beginning at one of its points.

a) The length of AB is given as follows: 14.387.
b) The measure of angle BAC is given as follows: 78.4º.
How to obtain the length of AB?The length of AB, from the sketch of the triangle given by the image at the end of the answer, is obtained using the law of cosines, as follows:
x² = a² + b² - 2abcos(C).
The parameters from the triangle are given as follows:
a = 8, b = 15, C = 70º.
Hence the length of AB is given as follows:
x² = 8² + 15² - 2 x 8 x 15 x cos(70º)

if the percentage increase is 79%, what is the growth factor?
PLS HELP TYSMMM
With an increase of 79% the growth factor is 1.79.
What is growth factor?The rate at which a quantity multiplies itself over time is known as its growth factor.
A quantity's growth rate is the factor by which it grows (or shrinks) over time.
An increase of 79% is the same result as multiplying with 1.79.
We call 1.79 a growth factor.
In other words:
With an increase of 79%,
you will get 100+ 79 = 179%.
The growth factor that corresponds with 179% = 179 : 100 = 1.79.
Written as a formula, it looks like this:
With an increase of p % the growth factor is
g = (100 + p) / 100
Simplifying,
g = 1 + p /100
g = 1 + 79/100
g = 1 + 0.79
g = 1.79.

This equation expresses x as a function of y, meaning y is the input and x is the output. This inverse equation can be used to solve for x when given a value of y
x = (y - 1) / 16
In order to find the inverse of a given equation, we need to switch the x and y values and solve for the new x. To do this, we start by subtracting 1 from both sides of the equation to isolate the y variable. Then, we divide both sides of the equation by 16 to find the inverse equation, x = (y - 1) / 16. This equation expresses x as a function of y, meaning y is the input and x is the output. This inverse equation can be used to solve for x when given a value of y

When I. there is a lot of scatter around the regression line, b1 is higher.
Define regression.A statistical measure that identifies the link or co-relationship between two variables. explains the relationship between an independent variable and a dependent variable. The scatter of data points around the regression line plays a key role in estimating the slope's uncertainty in regression analysis. The data points are more dispersed and the estimation of the slope is less accurate when there is a lot of scatter. Because the estimation of the slope is based on the data points, it is less accurate when there is greater scatter in the data points.
Given
When I. there is a lot of scatter around the regression line, b1 is higher.
I am higher. The uncertainty surrounding the slope estimate, b1, increases with the amount of scatter around the regression line. The calculated slope is less dependable when there is a lot of scatter than when there is very little scatter.
When there is a large amount of scatter around the regression line, the uncertainty associated with the slope estimate, b1, is higher. This is due to the fact that the estimate of the slope depends on the data points, and when there is a lot of scatter, the data points are more dispersed, making the estimate of the slope less accurate.

The slope is rise/run or (y2 - y1) / (x2 - x1)
We see the y decrease by 2 and the x increase by 8, so the slope is
-2/8 = -1/4
Answer:
Slope = -1/4
Step-by-step explanation:
Now we have to,
→ find the needed slope.
Formula we use,
→ Slope(m) = (y2 - y1)/(x2 - x1)
Then the slope will be,
→ m = (y2 - y1)/(x2 - x1)
→ m = (1 - 3)/(-1 -(-9))
→ m = -2/(-1 + 9)
→ m = -2/8
→ [ m = -1/4 ]
Hence, the slope is -1/4.

Which relation is not a function?A relationship is not a function if each input does not have a distinct output. For a relation to be a function, each input must have a distinct output, and the order of the set's items must be paired in a unique way or the elements of sets must be mapped in a unique way.A function is a special type of relation in which each element in the domain is paired with exactly one element in the range. For example, the relation {(1, 2), (3, 4), (5, 6)} is a function because each element in the domain (i.e., {1, 3, 5}) is paired with exactly one element in the range (i.e., {2, 4, 6}). On the other hand, the relation {(1, 2), (3, 4), (1, 6)} is not a function because the element 1 is paired with two elements in the range (2 and 6).All the set ot values agrees with this definition except the B, because the third and fourth pair have the same first value (3)Complete question :

Determine the largest integer value of x in the solution of the following inequality.
2x+6<-4
Answer: -6
Step-by-step explanation: To determine the largest integer value of x in the solution of the inequality 2x+6<-4, we first need to isolate x on one side of the inequality. We can do this by subtracting 6 from both sides of the inequality, which gives us 2x<-10. Next, we can divide both sides of the inequality by 2, which gives us x<-5. Since the inequality has a strict inequality symbol, we can conclude that the largest integer value of x that satisfies the inequality is -6.
