well, plug in -x+13 for y and you get
-x+13 = x^2+6x+7
x^2+7x-6 = 0
This has two solutions, but they are not listed among the choices. Check for a typo.
What are the solutions to the systems?
y=x^2+6x+7
y=-x+13
A. (-1,14) and (6,7)
B. (-1,7) and (6,14)
C. (-1,13) and (6,7)
D. No solution
I think its D.
