Let f(x)=8x. The graph of f(x) is transformed into the graph of g(x) by a vertical stretch of 4 and a translation of 7 units down.
What is the equation for g(x)?
Enter your answer in the box.
g(x)= ????
Answer:
g(x) = 32x-7
Step-by-step explanation:
A vertical stretch is shown in an equation by multiplying the equation by a factor greater than 1. Since we are stretching by a factor of 4, we multiply the equation by 4:
g(x) = 4(8x) = 32x
A vertical translation is performed by subtracting a value from a function. To translate the function 7 units down, we will subtract 7 from the equation:
g(x) = 32x-7
The equation for g(x) = 32x - 7.
Given that,
Let f(x) = 8x,The graph of f(x) should be transformed into the graph of g(x) by a vertical stretch of 4 and a translation of 7 units down.Based on the above information, the calculation is as follows:
g(x) = 4(8x)
= 32x
Now here we subtract 7 from the equation.
So, it is g(x) = 32x-7
Therefore we can conclude that the equation for g(x) = 32x - 7.

Mr. Malone used 40 pounds of insecticide to cover 1,760 square feet of lawn and 60 pounds to cover an additional 2,640 square feet. how many pounds of insecticide would Mr. Malone need to cover his whole lawn of 4,480 square feet?
Answer:
101.8182 pounds.
Step-by-step explanation:
He used 40 pounds of insecticide to cover 1760 square feet of lawn and 60 pounds to cover an additional 2640 square feet. So,
1760 + 2640 = 4400 square feet of lawn with 40+60 = 100 pounds of insecticide. Then, his whole lawn is 4480 square feet andn he already covered 4400, so he need to cover 4480 - 4400 = 80 square feet more.
Now, one of the data given we can do a proportion:
40 pounds to 1760 square feet = [tex]\frac{40pounds}{1760ft^2}[/tex]
x pounds to 80 square feet = [tex]\frac{xpounds}{80ft^2}[/tex]
[tex]\frac{40pounds}{1760ft^2}=\frac{xpounds}{80ft^2}[/tex]
[tex]xpounds*1760ft^2 = 80ft^2*40pounds[/tex]
[tex]xpounds = \frac{80ft^2*40pounds}{1760ft^2}[/tex]
[tex]xpounds = \frac{3200pounds}{1760}[/tex]
[tex]x = 1.8182 pounds.[/tex]
Then, to cover his whole lawn of 4480 square feet he needs 100+1.8182 = 101.8182 pounds of insecticide.

The midpoint of EF is M (4,10) one endpoint is E (2,6). Find the coordinates of the of the other endpoints F.
6,14
6,17
10,17
14,8
By applying this formula and solving for the unknown coordinates, the coordinates of endpoint F are determined to be (6, 14).
The student is asking to find the coordinates of the other endpoint F of a line segment EF given that the midpoint M is (4,10) and one endpoint E is (2,6). To find the coordinates of F, we can use the midpoint formula which states that the midpoint's coordinates are the averages of the endpoints' coordinates:
Midpoint Formula
Mx = (Ex + Fx) / 2
My = (Ey + Fy) / 2
Knowing the coordinates of endpoint E (2, 6) and midpoint M (4, 10), we can set up two equations to solve for the coordinates of F.
Finding Fx
4 = (2 + Fx) / 2
=> Fx = 4 * 2 - 2
=> Fx = 6
Finding Fy
10 = (6 + Fy) / 2
=> Fy = 10 * 2 - 6
=> Fy = 14
Therefore, the coordinates of the other endpoint F are (6, 14).

−4x−2y=−12
2x+4y=−12
(?,?)
Please Help!
Answer:
The solution of the equation −4x−2y=−12 , 2x+4y=−12 are (6 , -6) .
Step-by-step explanation:
As given the equations are
−4x−2y = −12
Simplify the equation
-2(2x + y) = -12
2x + y = 6
Another equation
2x+4y=−12
2(x+2y) = −12
x + 2y = -6
Two equation becomes
2x + y = 6
x + 2y = -6
Multiply x + 2y = -6 by 2 and subtracted from 2x + y = 6 .
2x - 2x + y - 4y = 6 + 12
-3y = 18
[tex]y = \frac{-18}{3}[/tex]
y = -6
Putting the value of y in the equation
2x + -6 = 6
2x = 12
[tex]x = \frac{12}{2}[/tex]
x = 6
Therefore the solution of the equation −4x−2y=−12 , 2x+4y=−12 are (6 , -6) .

Which of the following equations represents a line that is perpendicular to the line that passes through the points below?
(-8, -10) (-6, -2)
Thank you!
By calculating the slope of the line passing through the given points to be 4, the slope of any line perpendicular to this would have the opposite reciprocal, -1/4. Without a specified point for the line to pass through, (0,0) is used and the equation of the perpendicular line is y = -1/4x.
Explanation:The first step to finding a line perpendicular to another is understanding the concept behind the slope of a line. The slope of a line is determined by comparing the vertical change (rise) to the horizontal change (run) between two points on a line.
For the points (-8, -10) and (-6, -2), the slope would be calculated as follows: (change in y)/(change in x), which in this case would be (-2 - (-10))/(-6 - (-8)). Simplifying that expression gives us a slope of 4.
The opposite reciprocal of 4 is -1/4 (we flipped the fraction and changed the sign). This is the slope of all lines perpendicular to the original line.
Lastly, for the equation of a line, we need a point for the line to pass through, since the question didn't specify a point, we can use (0,0), so the equation of our perpendicular line is y = -1/4x.

The average rate of change of the given function is 9.
Given that, a function f(x) = x²+9x+18, we need to find the average rate of change for the function given,
So, the average rate of change = f(b)-f(a) / b-a
Here, a and b are -10 and 10,
So, f(-10) = 100-90+18 = 28
f(10) = 100+90+18 = 208
So, the average rate of change = 208-28 / 10+10
= 180 / 20 = 9
Hence, the average rate of change of the given function is 9.
