Answer:
f^-1 (x) = x/5
Step-by-step explanation:
f(x) = 5x
Replace f(x) with y
y= 5x
Exchange x and y
x = 5y
Solve for y
Divide each side by 5
x/5 = 5y/5
x/5 = y
The inverse is x/5

I wrote it on a phone, so it'll look different from a PC.
For this case we have the following data:
Area of the rectangle, 
Relationship of the sides 5: 3
By definition, the area of a rectangle is given by:

Where
- b: it is the side of least length.
If the sides have a 5: 3 ratio, it means:


Substituting in the formula of the area, we have:


Clearing b:
