Answer:

B. $f^{-1}(x)=\frac{x-4}{5}$

Step-by-step explanation:

To find the inverse of a function/equation:

Replace f(x) with y: y=5x+4
Switch x and y: x=5y+4
Solve for y: x-4=5y -> $y=\frac{x-4}{5}$
Write in standard inverse notation: $f^{-1}(x)=\frac{x-4}{5}$

SOLVE THIS PROBLEM ASAP

zepelin [54]

Answer:

Step-by-step explanation:

Use the exponent rule

Simplifying the top of the fraction

5^2*5*5^3=5^2+1+3=5^6

Simplifying the bottom of the fraction 5^4*5=5^4+1=5^5

Our simplified fraction is 5^6/5^5, which is just 5^6-5 which is 5^1 or 5.

Therefore, the answer is 5.
