<u><em>Answer:</em></u>7
<u><em>Explanation:</em></u><u>We are given the equation:</u>
</span>

<span> * c
We want to get the value of the equation at <u>c = 8</u>.
Therefore, all we have to do is <u>substitute c in the equation with 8 and solve</u> as follows:

<span> * 8
= </span>

<span>
The 8 in the numerator will be cancelled out with the 8 in the denominator leaving us with only the <u>7 as a solution</u>
Hope this helps :)</span>
A) (f∘g)(-1) = f(g(-1)) = f(1) = -1
b) (g∘f)(1) = g(f(1)) = g(-1) = 1
c) (f∘f)(1) = f(f(1)) = f(-1) = -5

Answer:
<em>Addition Property of Equality</em>
Step-by-step explanation:
<u>System of Equations</u>
When two equations are given and two variables are unknown in both equations, then we can solve the system in several ways.
One method consists in adding both equations term by term and eliminate one of the variables. That property is called the addition of equalities. Let's consider the equations given in the problem:

If we add both equations, we have

Simplifying

By adding both equations we managed to eliminate the variable y and could easily find the value of x
