The vertex is exactly half way between directrix and focus. In this case the vertex is (8,-7)
(h,k)
P is the distance between the vertex and either the directrix or focus, in this case p = 1.
a = 1/(4p) or 1/(4*1) or 1/4
write the equation in vertex form
y = a(x-h)^2 + k
y = 1/4(x-8)^2 -7
The answer is 1 mile an hour
X=4
You have to distribute the negative sign for everything in the parentheses. After that you add x to the other side then add 8 to the opposite side to move them. Then your answer is 4.
Here's y
y=<span><span><span><span>−<span>8x</span></span>+29
</span><span><span>−x</span>+<span>3
Hope this helps:)

Answer:
Step-by-step explanation:
Add 4 to both sides
13 + 4 = w/-3 - 4 + 4
17 = w/-3 Multiply through by -3
17*-3 = -3*(w/-3)
-51 = w
