A. x > 2
B. x > -7
C. x< 2
D. -7 < x < 2
E. none of the above.
So, -2 < x < 7
In other words, x can have any value between -2 and 7
So, let's say that I have, in my pocket, a number between -2 and 7
Which of the following must be true about that number?

B) x > -7
Must it be true that the number in my pocket is greater than -7?
Yes. If the number in my pocket is between -2 and 7, then that number MUST BE greater than -7

Answer: B

Cheers,
Brent
