15

Step-by-step explanation:

X*Y=814

X+Y=59

X=814÷Y

X=59-Y

814/Y=59-Y

814=(59-Y)*Y

814=59Y-Y²

Y=22

X+22=59

X=37

37-22

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
