Answer:
x=15
y=18
Step-by-step explanation:
then x+y=33
and 2x+5y=120
then x=33–y
since 2x+5y=120
then 2(33–y)+5y=120
then 66–2y+5y=120
then 66+3y=120
then 3y=120–66
then 3y=54
then y=54/3
then y=18
then x=33–18=15
Answer:
B
Step-by-step explanation:
IV does not represent y as the function of x since the ordinates share the same abscissa. As we can see in the graph {(4,-1),(4,4),(-4,-1),(-4,4)}
