Final answer:
The inequality that could be used to solve the problem is 3x≥−6.
Step-by-step explanation:
The inequality that could be used to solve the problem is B. 3x≥−6.
This inequality states that three times a number is no less than negative six. By multiplying a number by 3, the resulting value must be greater than or equal to -6.
For example, if we substitute a number like -2 into the inequality, we get 3*(-2) = -6, which is equal to -6. Since the inequality is 'greater than or equal to', -2 satisfies the inequality.
