B. 1
C. 2
D. 3
Answer:C
How many solutions exist to the equation |x| = |2x - 1| ?
A. 0 B. 1 C. 2 D. 3
Explanation: C If |x| = |2x - 1|, either x = 2x - 1 or -x = 2x - 1. The solutions to these equations are 1 and , respectively. However, the only thing you need to recognize is that the equation has two different solutions to establish that the answer is (C).
