Therefore, the inverse of f(x)=-8x+4 is (4-x)/8
What is mathematic expression?
A mathematical expression is defined as the collection of the numbersvariables and functions by using signs like addition, subtraction, multiplication, and division.
here, the function given is f(x) = -8x+4
and to find its inverse we replace f(x) = x and x = f(x) and solving for f(x) we get :
f(x) = -8x+4
x = -8f(x) +4
8f(x) = 4-x
f(x) = (4-x)/8
Therefore, the inverse of f(x)=-8x+4 is (4-x)/8

To find the inverse of f(x) = -8x + 4,
1) replace "f(x)" with "Y:" y = -8x + 4
2) interchange x and y: x = -8y + 4
3) solve this result for y: -8y = x - 4, or y = (x - 4)/(-8)
-1
4) replace this "y" with f (x): ":
-1 x - 4
f (x) = - ----------

Answer:
$75
Step-by-step explanation:
(45 / 3) x 5 = 75
To find the amount of money for each t-shirt, divide 45 by 3.
45 / 3 = 15
To find out the price of 5 t-shirts, multiple 15 by 5.
15 x 5 = $75
$75 is your answer :)
