If z + | z | = 0, which of the following must be true?	Choose the correct choice from the following answers
A) z > 0  B) z≥0  C) z< 0  D) z≤0  E) z = 0
Manipulate the equations:   z + | z | = 0   |z| = -y   -z &gt; 0 OR -z = 0   This means z could be 0 or z is less than 0.   D. z≤0   E. z=0   Answer: z≤0
<result>D</result>
