Answer:
12
Step-by-step explanation:
80-56=24
16/8=2
24/2=12
Fun fact
if f(a)=b then f⁻¹(b)=a
so
if f⁻¹(b)=a then f(a)=b
so we find f(x)=27 and the solve for x
f(x)=3x=27
3x=27
divide both sides by 3
x=9
so if f(9)=27 then f⁻¹(27)=9
problem solved
answer is 9
Answer:
1.50
Step-by-step explanation:
8 x 1.50=12
25-12=13
