Step-by-step explanation:
Given the system of equations;
-2x+15y = - 24 1
2x + 9y = 24 2
Using Elimination method
Add both equations
15y + 9y = -24 + 24
24y = 0
y = 0/24
y = 0
Substitute y = 0 into 2
From 2;
2x + 9y = 24
2x + 9(0) = 24
2x = 24
x = 24/2
x = 12
Hence the solution to the system of equation is (12, 0)

The vertex of a parabola given by y = a(x - h)^2 + k is (h, k).
Therefore, the vertex of y = (x + 1)^2 - 2 is (-1, -2)
