Answer:
Center: (2, -11)
Radius: 10
Step-by-step explanation:
(x - 2)² + (y + 11)² = 100
(x - h)² + (y - k)² = r²
-------------------------------
x - 2 = 0
+2 +2
x = 2
------------
y + 11 = 0
-11 -11
y = -11
------------------------------
r² = 100
r = √100
r = 10
----------------------------
Center: (h, k)
Radius: r
-------------------------------
Center: (2, -11)
Radius: 10
I hope this helps!

52 and 65 those are the ages of principles between 50%
Answer:
x=55,y=20
Step-by-step explanation:
180-75=105
2x-5=105
2x=110
x=55
4x+25=105
4y=80
y=20
X = -4 y = 2(-4) - 4 = -8-4 = -12
just plug in the other 2 values into 2x - 4 and work them out as above
