#4 which input is not allowed?

x = -2

Step-by-step explanation:

Since we cannot divide by 0, the value of x which results in a denominator that is 0 is a value excluded from the domain;

This value can be found by setting the denominator equal to 0;

In this case, the denominator is -5x - 10 so we construct the following equation and solve;

-5x - 10 = 0

5x = -10

x = -2

Step-by-step explanation:

-5x-10≠ 0

-5x≠ 10

x≠ -2

-2 is not allowed i.e option A

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

what's the question?

step-by-step explanation:

there is no question.
