1. Which of the following statements about absolute value is not true?
a. The absolute value is a number's distance from zero.
b. Absolute value is always positive.
c. The absolute value of a number is the same as the number's opposite.
d. Absolute value is indicated by two vertical lines around the number.
I'm pretty sure it's C because I know that A and B are true. That just leaves C and D. I think I know that D is true. The only one I have no knowledge on is C. Sorry this explanation stinks.
