Which equation, when graphed with the given equation, will form a system that has no solution? a)y=3x+6 b)y=-3(x+6) c)y=-3(x-2) d) y=3(x-2)

The correct answer is B.

This is because for two lines to have no solutions they must have the same slope and different y intercepts. In this case we can distribute the -3 in the B equation and see this is precisely what we get.

y = -3(x + 6)

y = -3x - 18

Since the slopes are now the same in both equations (-3) and the intercepts are different (6 and - 18), we know they are parallel and have no solution.

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242
