Help please , will medal what is the value of |x| + y when x = -3 and y = 15 ? A. -12 B. 18 C. -18 D. 12

OpenStudy (campbell_st):

well absolute value is only looking at magnitude and not direct. or it is only looking at the distance from the origin and not the direction this means \[\left| -a \right| = a\] so what do you think \[\left| -3 \right| =?\]
