Question

Which represents the solution(s) of the graphed system of equations, y = x2 – 2x and y = –2x – 1? (1, –1) (0, 0) and (0, –1) (0, 0) and (2, 0) no solutions

Answer 1

the correct answer is

D)no solutions

just took the test

Answer 2

Y = x^2 - 2x
y = -2x - 1

x^2 - 2x = -2x - 1
x^2 - 2x + 2x + 1 = 0
x^2 + 1 = 0
x^2 = -1
x = square root (-1).........NO SOLUTIONS
