Question

The first three steps in determining the solution set of the system of equations, y = –x2 – 2x + 8 and y = 2x + 11, algebraically are shown in the table.
Which represents the solution(s) of this system of equations?

Answer 1

All three of the steps shown are correct. Finish the solution by solving

0 = (x+1)(x+3). The solutions are x= -1 and x = -3.

Now subst. -3 for x in either of the given equations, to find the corresponding y.

Next, subst. -1 for x in either of the given equations, to find the corresponding y.

Answer 2

Answer:

The answer above shows how to solve, me well I'm a pretty straight forward person. Physically pretty OH GAWD NO, anyways the answer is A (-3,-1)
