Answer: 25
Step-by-step explanation:
Answer:
y = -11/4 (x − h)² + k
Step-by-step explanation:
Vertex form of a parabola is:
y = a (x − h)² + k
where (h, k) is the vertex.
Given that the vertex is (-3, 28):
y = a (x + 3)² + 28
Given that a point on the curve is (-5, 17):
17 = a (-5 + 3)² + 28
-11 = 4a
a = -11/4
y = -11/4 (x − h)² + k
First step is to add like terms, so 6q plus q equals 7 q then what's left is the 8, therfore you answer is 8+7q
