If the drawing is 5 inches tall and the ratio is 1:7, that means that 1 inch will be equal to 7 feet.
Height = 5 x 7 = 35 feet
Answer:
f-¹(x) = 2x – 8
f-¹(4) = 2(4) – 8 —> f-¹(4)= 8 - 8 =0
Assuming simplify then
get rid of parenthasees by assuming that there is a 1 in front of each, so multply by 1 and get rid of partenthasees so
5p^2-3+2p^2-3p^3
add like terms
7p^2-3p^3-3
normally ordered with biggest exponenst to the left from left to right decending
so
-3p^3+7p^2-3

Step-by-step explanation:
f(x=2x-7
Solving Steps
y=2x-7
Interchange the variables
x=2y-7
Swap the sides
2y-7=X
Move the constant to the right
2y=X+7
Divide both sides

Equation for line: y=mx+b where m is the slope and b is the y-intercept
We have the slope. We just need to find the y-intercept. Plug in the point and the slope and solve for b.
y=mx+b
1=4(-5)+b
b=21
Answer: y=4x+21
