@Ultrilliam

Zowie:

Give me a second.

Zowie:

It would be C.

JustSaiyan:

I can't answer this. I hate Algebra and all that it represents. I do Biology, History, Chemistry, Anything Science, and Translations. Not Math.

princeevee:

oh, well zowie can you answer some more?

Zowie:

I can try. :)

The center of a circle is located at (−2, 7) . The radius of the circle is 2. What is the equation of the circle in general form? x2+y2−4x+14y+51=0 x2+y2+4x−14y+49=0 x2+y2−4x+14y+49=0 x2+y2+4x−14y+51=0

Zowie:

It would be B. XD

The general form of the equation of a circle is x2+y2−4x−8y−5=0. What are the coordinates of the center of the circle?

Zowie:

The center is (2,4)

princeevee:

What is the equation of this circle in general form? x2+y2−2x−6y−26=0 x2+y2+2x+6y−26=0 x2+y2−2x−6y+4=0 x² + y² + 2x + 6y + 4 = 0

Zowie:

It would be A.
