Question

a number and its absolute value are equal.if you substract 2 from the number, the new number and its absolute value are not equal. what do you know about the number? what is a possible number that satisfies these conditions? Can you help answer these 2 questions? thanks

Answer 1

If x >= 0, |x| = x
If x < 0, |x| = -x

So, from what we have above,

x >= 0
x-2 < 0, or x < 2

So, 0 <= x < 2
