One way to locate the vertex is to obtain the coefficients a, b and c from the quadratic and then calculate
-(-16)
x = -b / (2a). Here, x = ---------- = -2
2(-4)
Next, evaluate y at x = -2: y = -4(-2)^2 - 16(-2) - 12 = -16 + 32 - 12
y = 4
the vertex is at (-2,4).
Do 27.5x10=2.750 it will give you that. Hope it helps
I believe your answer should be 3.
He should spend at least $4.00 on each 4.00/22
