Answer:
17x
Step-by-step explanation:
10+7 = 17
7-7 = 0
Answer: Center (0, -8) and Radius = 2
The standard equation of a circle is (x-h)² + (y-k)² = r² where (h,k) is the center and r is the radius.
You can write the equation as (x-0)² + (y-( -8))² = 2². From this, you can conclude that the center is (0,-8) and the radius is 2.
(x+5)/5+(y+9)/9=1
The center is (-5,-9)
c^2 = 9-5 =4
c=2
foci =2
(-5,-7) (-5,-11)
, or 1.75<u />
