Multiple Choice

A structural engineer is reviewing the safety tolerance xx (in millimeters) for a support beam. The beam is considered safe if the measurement xx satisfies the compound inequality:

35x71\frac{3}{5}x - 7 \le -1 or 13(x+6)2\frac{1}{3}(x + 6) \ge -2

After solving both inequalities, which of the following correctly identifies the total range of safe measurements for the beam in interval notation?
