Step-by-step explanation:
The given circle has equation
The equation of a circle with center (h,k) and radius r units is
This is the equation that has its center at the origin with radius 4 units.
When this circle is translated seven units to the right and five units up, then the center of the circle will now be at (7,5).
Answer:
A. 3x^2 + 4 = 52
3x^2 = 52 - 4
3x^2 = 48
x^2 = 48/3
x^2 = 16
x =
x = 4
B. x^2 - 121 = 0
x^2 = 121
x =
x = 11
C. (b + 4 )2 = 49
2b + 8 = 49
2b = 49 - 8
2b = 41
b = 41/2
