Answer:
Option D.
Step-by-step explanation:
We need to find an inequality that has –12 in its solution set.
Solve each of the given inequalities.
Option A,
Subtract 6 from both sides.
Since -12>-14, therefore -12 is not included in the solution set of x+6<-8.
Option B,
Subtract 4 from both sides.
Since -12<-10, therefore -12 is not included in the solution set of .
Option C,
Add 3 on both sides.
Since -12<-7, therefore -12 is not included in the solution set of x-3>-10.
Option D,
Subtract 5 from both sides.
Since -12<-9, therefore -12 is included in the solution set of .
Therefore, the correct option is D.
