A circle has center (5, -4) and radius 8. Which gives the equation of the circle? A) (x + 5)2 + (y - 4)2 = 8
B) (x - 5)2 + (y + 4)2 = 8
C) (x + 5)2 + (y - 4)2 = 64
D) (X - 5)2 + Hy + 4)2 = 64

A

Step-by-step explanation:

if not A then B but i'm pretty sure A

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
