Answer:
B.
Step-by-step explanation:
First, the equation must be solved, so x + 6 ≤ -9
Step 1: Subtract 6 from both sides to cancel the +6; The new equation is
x ≤ -15.
This means that the inequality must have a filled in circle starting at -15, and an arrow going to the left because -15 is greater.
For proof, substitute -20 for x:
-20 ≤ -15 ←This is true
