Answers with explanations

Answer 1

To answer this question, try to solve the system of equations.  Start by plugging in "$x^{2} +3x-7$" in for y in the second equation:

$x^{2} +3x-7-5x+8=0$

*Combine like terms*

$x^{2} -2x+1=0$

*Factor*

$(x-1)(x-1)=0$

*Set each term equal to 0*

x-1=0

*Add 1 to both sides*

x=1

C) There is exactly 1 solution.

Hope this helps!!
