Answer:

Step-by-step explanation:

Length of:

First piece = x

Second piece = 4x

Third piece = 5x

Equation: 30 = 4x + 5x + x

Solving the Equation:

10x = 30  

x = 3

Lengths of:

First piece = 3 inches

Second piece = 12 inches

Third piece = 15 inches

Given the function f(x) = 3x, find the value of f−1(27). f−1(27) = 1 f−1(27) = 3 f−1(27) = 9 f−1(27) = 81
Mariulka [41]
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
