Select all the correct systems of equations.
Which systems of equations have Infinite solutions?
2x + 5y = 31
6x - y = 13
2x + y = 10
-6x = 3y + 7
y = 14 - 2x
6x + 3y = 42
y= 13 - 2x
4x - 3y = -19
2x + y = 14
x = 13 - 2y
2x + y = 17
-6x = 3y - 51

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,

step-by-step explanation:

answer: .75 km

step-by-step explanation:

maximum area = xy = (16)(32) = 512 ft2
