Absolute value is a function that takes some number and outputs the size of that number, regardless of the sign. By definition, 
if 
, and 
if 
.
For example,
- |2| = 2 because the input 2 is positive, so the input is unchanged;
- |-3| = -(-3) = 3 because the input -3 is negative, so the sign is switched.
What this means for this problem is that there are two cases to consider:
- If
, then 
, so that
- On the other hand, if
, then 
, so
First off, the function above is incomplete, however, by the looks of it, likely a quadratic, anyway, the values "x" can safely take on would be all real numbers, thus -∞ < x < +∞
Melissa is represented by variable m.
Josh is represented by variable j.
Chau is represented by variable c.
m+j+c= 148
c=4m
j=m+10
Substitute for c and j for the first equation.
m+(m+10)+4m=148
6m+10=148
6m=138
m=23
Plug the known m value in
j=23+10
j=33
c=4(23)
c=92
Final answer: Melissa=23 messages, Josh=33 messages, Chau=92 messages
