Coordinates of the center: ( 4, 4 )
The radius: r = 7 - 4 = 3
The equation of a circle:
( x - 4 )² + ( y - 4 )² = 3²
x² - 8 x + 16 + y² - 8 y + 16 = 9
x² + y² - 8 x - 8 y + 32 - 9 = 0
Answer:
A ) x² + y² - 8 x - 8 y + 23 = 0

Answer:
(d) 16
Step-by-step explanation:
Angles opposite sides of the same measure are congruent. Here, the triangle is isosceles, so the base angles are congruent:
2x = 32
x = 16 . . . . . . divide by 2°
X: -4, -2
Y: 2, 3
When you plug -4 and 2 it looks somewhat like this, 4(2)-2(-4)= 8+8+16. Then -2 and 3 would look something like this, 4(3)-2(-2)= 12+4=16.
Answer:
I think it is Letter B.............
The answer is 9.
This is a cube root.
9 cubed, or 9 the the third power, is 729
