What is the simplified form of 2 times the square root of 5x to the 3rd power times -3 multiplied by square root of 10x squared? a.-30 times √2x^5 b. -30x^2 times the √2x c. -12x^2 times the √5x d. -6 times the √50x^5

B.)-30x^2(square root 2x)    correct on edge

i can't see the picture : /

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
