Question: 489

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

A. –6
B. –4
C. –2
D. 0
E.

Correct Answer: A

Explanation:

A The question is essentially asking which of the answers cannot be a value of x. So just try each answer one at a time by plugging the number into each of the two inequalities in the question, and see which one doesn't fit. If x = –6, is –6 + 6 > 0? No, because zero is not greater than zero. So –6 is the exception.
