Select the rational expression that is equivalent to the given expression below. 4/x-3

Aliun [14]

To find the correct option we need to calculate each of the given options.
Option (1):
$\frac{x+2}{x-3} / \frac{4}{x+2} = \frac{x+2}{x-3} * \frac{x+2}{4} = \frac{(x+2)^2}{4(x-3)}$

Option (2):
$\frac{x+2}{x-3} * \frac{4}{x+2} = \frac{4}{x-3}$

Option (3):
$\frac{x+2}{x-3} - \frac{4}{x+2} = \frac{(x+2)^2-4(x-3)}{(x-3)(x+2)}$

option (4)
$\frac{x+2}{x-3} + \frac{4}{x+2} = \frac{(x+2)^2+4(x-3)}{(x-3)(x+2)}$

So, the correct answer is option (2)

Select the graph of the solution set that would represent the following expression. (x-2)=5(x+1)

Lesechka [4]

Answer:

Find the attached

Step-by-step explanation:

We have been given the following expression;

(x-2)=5(x+1)

We are required to determine the graph of the solution set. To do this we formulate the following set of equations;

y = x - 2

y = 5(x+1)

We then graph these two equations on the same cartesian plane. The solution will be the point where these two graphs intersect.
