Evaluate:|-12| - |4|- |-8|?

when you evaluate a number if it is positive do nothing if it is negative switch it to a positiive sooo 12   4    and   8 :)

Step-by-step explanation:

range is infinite on both x and y axis positive and negative

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
