Question 631563
"which function is the inverse of f(x)=-1/5x+8"

hey so here's how you do it

1. substitute "y" for f(x) so now the equation will be

y=-1/5x+8  now, switch the y and the x. the equation will now be

x=-1/5y+8  since you want to leave the y all by itself,  x-8=-1/5y

divide everything by -1/5 and the equation will become x-8/-.2=y

now rewrite this in the proper form as f^-1=x-8/-.2

Answer= f^-1=x-8/-.2

hope this helps! good luck
