Question

Write the equation of a circle with a center at (–7, –7) and a radius of 7.


(x + 7)2 + (y + 7)2 = 14

(x + 7)2 + (y + 7)2 = 49

(x – 7)2 + (y – 7)2 = 49

(x + 7)2 + (y + 7)2 = 7

Answer 2

Sorry I wasn't on :(

But the equation of a circle is

\[\large (x - h)^2 + (y - k)^2= r^2\] where \(\large h,k\) is the center of a circle and r is the radius...so here

\[\large (x + 7)^2 + (y + 7)^2 = 7^2\]
\[\large (x + 7)^2 + (y + 7)^2 = 49\]

Answer 3

no its okay :) thankn you so much @johnweldon1993

Answer 8

What is the equation of the ellipse with foci (0, 6), (0, -6) and co-vertices (2, 0), (-2, 0)?


x squared divided by 1 plus y squared divided by 36 equals 1

x squared divided by 1 minus y squared divided by 36 equals 1

x squared divided by 1 plus y squared divided by 40 equals 1

x squared divided by 1 minus y squared divided by 40 equals 1
