20 select the system of linear inequalities whose solution is graphed. (the image goes here) a. x < –3; y ≤ –x – 1 b. x ≤ –3; y ≤ –x – 3 c. x < –3; y ≤ –x + 1 d. x < –2; y ≤ –x – 1 !

its 4 because 2 times 2 is 4, if you double the number two you get four

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
