Which is the equation of a parabola with a directrix at y = 2 and a focus at (5, 0). y = one fourth(x − 5)2 + 1 y = one fourth(x + 1)2 − 5 y = −one fourth(x + 1)2 − 5 y = −one fourth(x − 5)2 + 1

check the picture below.

so, the directrix is above the focus point, meaning the parabola is opening downwards and is vertical, since it's vertical the squared variable is the "x", and since it's opening downwards, the "p" distance from the vertex is negative.   recall that the vertex is half-way between those two folks the focus and directrix, as you see in the picture, and the distance "p" is one, but negative thus p = -1.

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
