Question 20

Use inequality notation to describe the set. t is at least -14 but less than 17
A) -14 $\le$ t $\le$17
B) -14 $\lt$ t $\lt$ 17
C) 17 $\le$ t $\lt$ -14
D) 17 $\lt$ t $\le$-14
E) -14 $\le$ t $\lt$ 17

Accepted Answer

The inequality notation for "t is at least -14 but less than 17" is -14 ≤ t < 17. This means t can be equal to -14 but cannot be equal to 17. Option E correctly shows this notation with the appropriate less than and less than or equal to signs.
