which compound inequality is graphed on the number line?

a. 5x ≥ -25 and -6x ≤ -30
b. 3x ≥ -12 and 8x ≤ 16
c. 4x ≥ 12 and 5x ≤ -20
d. -3x ≥ -12 and -8x ≤ 16

b. 3x ≥ -12 and 8x ≤ 16

Step-by-step explanation:

Based on the graph, x is less than or equal 2 and greater or equal -4

So solution will be:

x ≥ - 4 and  x ≤ 2

OR  

-4 ≤ x ≤ 2

a. 5x ≥ -25 and -6x ≤ -30   --->NO because look at the first one

   5x ≥ -25

     x ≥ -5 >NOT a solution

c. 4x ≥ 12 and 5x ≤ -20   --->NO because look at the first one

   4x ≥ 12

     x ≥ 3 >NOT a solution

d. -3x ≥ -12 and -8x ≤ 16--->NO because look at the first one

   -3x ≥ -12

      x ≤ 4  >NOT a solution

b. 3x ≥ -12 and 8x ≤ 16 >YES

3x ≥ -12

Divide both sides by 3

 x ≥ -4  >YES

and

8x ≤ 16

Divide both sides by 8

  x ≤ 2 >YES

b. 3x ≥ -12 and 8x ≤ 16
