Answer 1

Answer:

B. (-1, 2) and (-5, -2)

Explanation:

You can determine that y equals x+3 from the first equation.

You can plug it into the other equation to find x.

Answer 2

Answer: B

Step-by-step explanation:

Let use the subsitution method. since y= x+3 we will set it equal to the quadratic.

x+3=$x^{2} +7x+8$ then subtract 3 from both sides

x=x^{2} +7x+5 then subtract x from both sides

x^{2} +6x+5 Then using the AC method the roots are (x+1)(x+5) set it equal to zero and the answers are x=-1, x=-5, plug that back i the equation and we get y=2 and -2 so B
