B. x≥-3
Step-by-step explanation:
To solve this problem, first you have to isolate it one one side of the equation.
First, multiply -1 from both sides.
(-9x)(-1)≥27(-1)
Solve.
27*-1=-27
9x≥-27
Next, divide by 9 from both sides.
9x/9≥-27/9
Then, solve.
-27/9=-3
Therefore, the correct answer is x≥-3.
