Well, 1000/5 would be smaller than 2000 not bigger. You are dividing into smaller pieces not multiplying into bigger ones.
W + 4 > -12
Subtract 4 from both sides
w = -16
Answer:
y = (x + 8)² + 6
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square
add/subtract (half the coefficient of the x- term )² to x² + 16x
y = x² + 2(8)x + 64 - 64 + 70
= (x + 8)² + 6 ← in vertex form
