(-5, 1) is the same because it is a dot

crimeas [40]

Step-by-step explanation:

I assume we are simplifying

1) -6k+7k = k

2) 12r-8-12 = 12r-20

3) n-10+9n-3 = 10n-13

4) -4x-10x = -14x

Find the center and the radius of the circle x2 + y2 − 2x + 6y − 6 = 0.

asambeis [7]

x 2 + y 2 + a x + b y = c

x2 + y2 − 2x + 6y − 6 = 0

Steps:

x^2 + y^2 - 2x + 6y - 6 = 0

(x - 1)^2 + (y - (-3)^2=4^2

Which means...

Center = (1,-3)

Radius = 4

Or option B
