Answer:
y=3
Step-by-step explanation:
K, so since directix is below focus, it opens up (2<4)
and directix is y=something so equation is (x-h)^2+4p(y-k) where (h,k) is vertex and p is distance from focus to vertex. if it opens down, p<0, if it opens up, p>0
and the vertex is in the middle of the focus and directix
so
distance bewten (-2,4) and y=2 is 2 units
2/2=1, so 1 unit down from focus
vertex is in the middle so it is at (-2,3)
also, opens up so p=1
vertex (-2,3)
p=1
(x-(-2))^2=4(1)(y-3)
(x+2)^2=4(y-3) is an equation
x=4
Add Six to both sides and get 3<span>√x-6+6=0+6
Divide both sides by 3 and get x</span><span>√2
</span><span>
Solve the square root and get x=2^2
Square both sides and get x=4
Plug in and get </span><span>3√x -6=0
</span>
Hope it helps
Your answer is 89 since 4*10=40)+5*5=25)+2*12=24, add all the results up and get 89.
