What are the integer values of x which satisfy the inequality -1 < 3 -2x (leq) 5?
-
A.
-1. 0, 1, 2 -
B.
-2, 1, 0 , -1 -
C.
0, 1, 2 -
D.
-1, 0, 1
Correct Answer: Option D
Explanation
-1 < 3 -2x and 3 – 2x (leq) 5
2x < 3 + 1 and -2x (leq) 5 – 3
2x < 4 and -2x (leq) 2
x < 2 and x (geq) 2/-2 = x (geq) -1
If -1 (leq) x < 2
it implies that x = -1, 0, 1
