Which system of linear equations can be solved using the information below?
o
o
2x-3y = 20
12x+8y=-192
20x-3y = 2
-192x+8y = 12
o-3x+2y = 20
8x+12y = -192
0 -3x+8y = 20
2x+12y =-192

step-by-step explanation:

the answer is 128

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

you,
