The equation of a circle:

(h, k) - center
r - radius
Look at the picture:
center: (4, -2) → h = 4, k = -2
radius: r= 5
Substitute:

28 because a constant is a number that doesn't have x attached to it.hope this helps

Answer: Table A
Step-by-step explanation:
The coefficient of x^2 is 1, the coefficient of x is -6, and the constant is 0. This means that a = 1, b = -6, and c = 0.
- This eliminates tables B and C.
Now, we need to determine if the graph opens up or down to differentiate between A and B. Since the coefficient of x^2 is positive, the graph opens up.
- Thus the answer is <u>Table A.</u>
Answer:
2x - 4
Step-by-step explanation:
2(3x + 6) = 6x + 12
2(-2x - 8) = -4x -16
6x + 12 - 4x - 16 = 2x - 4
