24% discount

18.50/25 = .76 or 76%

100% - 76% = 24%

F(x)= x+28/x-7 for inverse functions

The inverse function of the given function is $\mathbf{= \dfrac{28+7x}{x-1}}$

<h3>What is the inverse of a function?</h3>

A function g is the inverse of a function f, if and only if the values of y= f(x), x = g(y).

From the formula given:

$\mathbf{y=f(x) = \dfrac{x+28}{x-7}}$

Let's substitute x with y;

$\mathbf{y= \dfrac{x+28}{x-7}}$

$\mathbf{x=\dfrac{y+28}{y-7}}$

Solve for y;

$\mathbf{= \dfrac{28+7x}{x-1}}$

Pls dont write silly things or ill report. which number in each set is not a factor of the given number:

Allisa [31]

Answer:

a.(4)

b.(45)

Step-by-step explanation:

A factor is a number that divides perfectly without any remainder so you can try to divide each.

For example:

-14/2=7(it's a factor of 14)

-14/4=3.5(it's not factor of 14)

The equation P = 21 + 2w can be used to find the perimeter of a rectangle. A 1 point rectangular shaped playground is enclosed b

nalin [4]

Answer:

130 m

Step-by-step explanation:

<u>Given:</u>

P = 2l + 2w
P = 500 m

<u>Length is:</u>

l = 120 m

<u>Substitute values and solve for w:</u>

500 = 2*120 + 2w
2w = 500 - 240
2w = 260
w = 260/2
w = 130 m
