Question

What are the solutions of the system?

y = x^2 - 2x -2
y = 4x + 5

A. (–1, 1) and (–7, –23)
B. (–1, 1) and (7, 33)
C. (–1, 33) and (7, 1)
D. no solution

I Thinks It's A! Is That Correct?

Answer 1

substitute y=4x+5 into the longer equation to get:

4x+5=x^2-2x-2 combine like terms.
x^2-6x-7=0 Factor.
(x-7)(x+1)=0

Answer 2

no , its not a

Answer 3

oh :/ i sorta figured i did something wrong but my other guess was D. No solution

Answer 4
