Answer: x=3 and y=5
Step-by-step explanation: 11x-6y=3, 5x-8y=-25
11x-6y+6y=3+6y
11x/11=3/11+6y/11
x=3+6y/11
5(3+6y/11)-8y(11)/11
5(6y+3)-88y/11
30y+15-88y/11
88y-30y
58y
11(15-58y)/11=11(-25)
15-58y-15=-275-15
-58y/-58=-290/-58
y=5
x=3+6(5)/11
3+30
33
33/11
x=3
x=3, y=5
14. A
C=10+12h
I think one time fee is 10, the recurring fee is 12
15.B
c=2*12h=24h
initial value is going to be 0 because no one time fee, rate of change is 24
C=a*h+b(a is rate of change, and b is initial value)
