Step-by-step explanation:
-6 < 3x - 12 <= 9
6 < 3x <= 21 (add 12)
2 < x <= 7 (divide by 3)
The graph that correct represents this solution set is the 2nd graph.
3/10 in
<span>1 in =(1/12)ft </span>
<span>1 ft =(1/5280) mi </span>
<span>3/10 in=3/10*(1/12)*(1/5280) mi </span>
The first one is 2x+y=-1
the second one is 13x+2y-1=0
