If |r|=−r, which of the following must be true?
Choose the correct option
A) x≥0 B) r≤0 C) x2>x D) x3<0 E) 2x<x
|r| =-r means absolute value of r is equal to negative of r. Since absolute value cannot be negative hence negative of r should result in a non negative number. It means r is a non positive number i.e. r&lt;0. Answer is r≤0
