2x-8y=-24
A.Yes, Leslie is correct.
B. No, the solution is (-8,-24)
C. No, the solution is (0,-16)
<u>D. No, the system of equations has no solution. </u>
Step-by-step explanation:
you have to solve they as a pair of simultaneous equations and their is no solutions

F(x) = x² + x - 20 = x² + 5x - 4x - 20 = x(x + 5) - 4(x + 5) = (x + 5)(x - 4)
f(x) = 0 ⇔ (x + 5)(x - 4) = 0 ⇔ x + 5 = 0 or x - 4 = 0 ⇒ x = -5 or x = 4
Answer: C. x = -5 and x = 4.
