What is the inverse of the function y = -8x + 15? A. y = 1/8x + 15

B. y = -8x - 15

C. y = (x - 15)/-8

D. y' '= -1/8x + 1/15

c) ( x-15)/-8

Step-by-step explanation:

c) (x-15) / -8

Solution given:

y = -8x + 15

interchanging role of x and y

we get

x=-8y+15

solve for y

x-15=-8y

divide both side by-8

we get

-8y/-8=(x-15)/-8

y=(x-15)/-8

:.

C. y = (x - 15)/-8 is a required inverse.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

ab will be equal to
