**Question: 15**

**1.** If x + 6 > 0 and 1 - 2x > -1, then x could equal each of the following EXCEPT

- A. -6
- B. -4
- C. 0
- D.

**Correct Answer:** A

**Explanation:**

A Solve the first inequality by subtracting 6 from each side so that x > -6. You are looking for values that won't work for x, and x cannot equal -6. Therefore, the answer must be (A). Just to be sure, solve the next inequality by subtracting 1 from each side to get -2x > -2. Divide by -2, remembering to switch the sign because you are dividing by a negative number, to get x < 1. The values in (B), (C), and (D) fit this requirement as well, so they are values for x and not the correct answer.
