Answer:
ZERO
ZERO
Step-by-step explanation:
When finding x-intercepts, y is equal to zero. So, we can set the whole function equal to ZERO.
Then we set each binomial equal to ZERO.
Sue = 2 Sally
Sara = Sue - 1
= (2Sally) - 1
Sally + Sue + Sara = 49
Sally + 2 Sally + 2 Sally - 1 = 49
5 Sally = 49 + 1
5 Sally = 50
Sally = 10
Sue = 20
Sara = 19
15/100
Im pretty sure thats the answer :3

The standard equation of parabola:
(y-k)²=4p(x-h), with:
a) vertex = (h,k)
b) focus = (h+p, k)
c) directrix = (x=h-p)
Since this parabola has a vertex at (0,0) that means h=k=0
Hence the equation becomes: y²=4px, let's calculate p:
focus is given (-9,0) Remember h+p = -9 & since h=0, then p= -9
===> y²= - 36x
