How many solutions does the following system have? 2x- 4y = 11 -2x + 4y = -10

On a piece of paper, graph . then determine which answer choice matches the graph you drew

If the endpoints of the diameter of a circle are (8, 6) and (2,0), what is the standard form equation of the circle? a) (x + 5)2 + (y + 3)2 = 18 (x + 5)2 + (y + 3)2 = 3.72 (x - 5)2 + (y - 3)2 = 18 d) (x - 5)2 + (y - 3)2 = 32

Using elimination, what is -4x+2y=-12 4x+8y=-24
