Question

Which represents the solution(s) of the system of equations, y= x^2 - 4x - 21 and y = -5x - 22? Determine the solution set algebracically.

Answer 1

Answer:probably C

Explanation:

Answer 2

TO determine the solution set of the equations given above, we can use substitution method. We do as follows:
y = –x2 + 6x + 16 and y = –4x + 37
–x2 + 6x + 16 = –4x + 37-x^2 +10x -21 = 0x = 7 and 3y = 9 and 25
