The x on the bottom will cancel out the x on the top here.
Answer:
x=-2.5
Step-by-step explanation:
ok
sotake +9 to the other side
10x-6x=-1-9
4x=-10
divide both sides by 4x
x=-2.5
In this problem, given the focus at (2,4) and directrix at y = 8. then it is implied that the parabola is facing downwards. The vertex hence is at the middle of the focus and the directrix, hence at (2, 6). The general formula of the parabola is y-k = -4a ( x-h)^2. Substituting, y -6 = -1/8 *(x-2)^2. Answer is A.
