Question: The inequality |2x – 1| > 5 must be true in which one of the following cases? I. x < -5 II. x > 7 III. x > 0
(a) II only (b) I, II and II (c) I and II only (d) I and III only (e) I only
l 2x - 1 l > 5
We have two equations
2x - 1 > 5 and - (2x - 1 ) > 5
2x > 6 -2x + 1 > 5
x > 3 -2x > 4
x < - 2
I and II will make this inequality true
+92
