Finn had a job babysitting his neighbors' kids that paid $8 an hour and
he made between $120 and $272 (inclusive) every week.
If x is the hours he worked in a week and y is the money he made in a
week, write the domain and range of the function as compound
inequalities.

Answer:
C
Step-by-step explanation:
The 2 will only be in the front and not also after the = since you are combining those two equations.
Answer:
x=0
y=6
Step-by-step explanation:
3y- 12x = 18
2y-8x= 12
rearrange the equation
2y-8x=12
add 8x to both sides
2y=8x+12
divide both sides by 2
y=4x+6
now substitute it into 3y-12x=18
3(4x+6)-12x=18
simplify
12x+18-12x=18
simplify
18=18
x=0
substitute to find y
2y-8(0)=12
2y=12
y=6
Recheck:
3(6)-12(0)=18
18=18
2(6)-8(0)=12
12=12
