What is the inverse of the function y = -8x + 15?
2 answers:
Answer:
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.
Answer:
c) ( x-15)/-8
Step-by-step explanation:
c) (x-15) / -8
