Answer:

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

Step-by-step explanation:

Let y = f(x) and rearrange making x the subject

y = 4x ( divide both sides by 4 )

x = $\frac{y}{4}$

Change y back into terms of x

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

A library building is in the shape of a rectangle. Its floor has a length of (3x + 5) meters and a width of (5x − 1) meters. The

AleksAgata [21]

The problem says that the expression (3x + 5)(5x − 1) <span>represents the area of the floor of the building in square meters. Therefore, to solve this problem you have to follow the proccedure shown below.

1. First, to simplify the expression (3x + 5)(5x − 1) you must apply the distributive property. Then, you obtain:

15x</span>²-3x+25x-5

2. Then, you have:

15x²+22x-5

3. As you can see, the correct answer is the last option: 15x²+22x-5
