Answer:
B) f^-1(x)=3-5x
Step-by-step explanation:
y=3-x/5
rearrange the equation so you have x variable on the left side
5y=3-x
+x +x
5y+x=3
-5y -5y
x=3-5y
so answer is b)
f^-1(x)=3-5x
Start with

Simplify the left hand side by summing like terms (the one involving z):

Subtract 5z from both sides:

Subtract 7 from both sides

Divide both sides by 11:
