The equation of a circle is ​ (x−11)2+(y+15)2=144 ​ .<br><br> What is the circle's radius?
yuradex [85]
The equation of a circle is (x-h)^2+(y-k)^2=r^2, where (h,k) is the center and r is the radius.
To find the radius, we would find the square root of 144, which is 12.
r=12

Step-by-step explanation:

y = 3x + 2

6x – 2y = 10

Ryan’s answer:

6x – 2y = 10 → 3x – y = 5

6x = 7

x =

6x – 2y = 10 → 6 – 2y = 10

7 – 2y = 10

–2y = –3

y = -

Jesse’s answer:

I used matrices. The solution is .
