There is only case if ∠c=90
then Δ ACB is right angle triangle.
(hyp)^2=(base)^2+(height)^2
(AB)^2=(15)^2+(17)^2
Answer:
y=-2x-2.5
Step-by-step explanation:
-2y=x+5
--- --- ---
y= -2x - 2.5
assuming the -2y is negative if not its y=2x+2.5

Step-by-step explanation:
Answer: 
<u>Step-by-step explanation:</u>
The vertex form of a parabola is y = a(x - h)² + k or x = a(y - k)² + h
- p is the distance from the vertex to the focus
- -p is the distance from the vertex to the directrix

1) y = -2(x - 4)² - 1 → a = -2 (h, k) = (4, -1)

*******************************************************************************************
2) x = (y - 1)² + 2 → a = 1 (h, k) = (2, 1)
