Answer:
a=18
Step-by-step explanation:
Vertex is directly in middle of directix and focus
distance from 8 to -8 is 16
16/2=8
so 8 below focus (since 8>-8) is the point (0,0
vertex is (0,0)
nice
it opens up because focus is above directix
also it goes up down so
4p(y-k)=(x-h)^2
(h,k) is veretx
we got that (h,k) is (0,0)
and p is distance from vertex to focus which is 8
so
4(8)(y-0)=(x-0)^2
32y=x^2
y=(1/32)x^2
it would be 35/3 or 11 2/3
27-2(2w+1)=5w-2(5+w)
27-4w-2=5w-10-2w
25-4w=3w-10
25=7w-10
35=7w
5=w
brainliest :)
