answer
(x+7)^2 + (y-4)^2 = 64
set up equation
the equation of a circle is (x - h)^2 + (y - k)^2 = r^2
where h is the center x coordinate and k is the center y coordinate
values
from the point (-7,4) we know that h = -7 and k = 4
since the radius is 8, r^2 = 8^2 = 64
plug in values
now that we have all the values, we plug them into (x - h)^2 + (y - k)^2 = r^2
(x - h)^2 + (y - k)^2 = r^2
(x - (-7))^2 + (y-4)^2 = 64
(x+7)^2 + (y-4)^2 = 64
A ratio is not multiplication, so I'm just going to throw that out there first in case any other answers trip you up.
9:2 is the correct answer because there are 9 sandwiches for 2 people.
Answer: -9z + 15/x^2
The correct answer is -9z + 15/x^2 when simplified

15 8/100, or 15 4/50 in simplified version.
I hope this helps, please Brainliest me, and have a great day! :D
Answer:
(32,92) and (−1,2)
Step-by-step explanation:
You have to equal the two Ys, meaning their values as well or you can find the value of the first x and then plug it in the second equation. There are many ways to solve this to.
