In order for you to get the answer you must divide. Find a number the goes into both 9 and 81. You're lucky 81 is a multiple of 9. So we can use 9. So 9/81 divided by 9.
9/9=1
81/9=9
So 9/81=1/9
It Given the focus (h,k) and the directrix y=mx+b, the equation for a parabola is (y - mx - b)^2 / (m^2 +1) = (x - h)^2 + (y - k)^2.
Answer:
x=-7 y=3
Step-by-step explanation:
5x+10y=-5
-5x-y=32
9y=27
y=3
5x+10(3)=-5
5x+30=-5
5x=-35
x=-7
