Henry was thinking of a number. Henry halves the number and gets an answer of 32.5. Form an equation with x
from the information.

Asap! i'm not good math and i'm lost.

How is the equation of this circle written in standard form? x2 + y2 - 6x + 14y = 142 a) (x - 3)2 + (y + 7)2 = 200 b) (x+ 3)2 + (y - 7)2 = 200 (x - 6)2 + (y + 14)2 = 142 d) (x+6)2 + (y- 14)2 = 142
