Answer:
3x+2y=18.65
Step-by-step explanation:
For this case we have a system of two equations with two variables:

Equaling the equations we have:

Adding x to both sides of the equation we have:

Adding 4 to both sides of the equation we have:

Dividing 2 on both sides of the equation we have:

We find the value of the variable y:

Thus, the system solution is:

Answer:

5y+30+2y<4y+8
5y+2y-4y<8-30
3y<-22
y<-22/3
Answer:
f(2) = 15.5
f(3) = 18
f(4) = 20.5
f(5) = 23
f(6) = 25.5
g(2) = 64
g(3) = 96
g(4) = 128
g(5) = 160
g(6) = 192
Step-by-step explanation:
plug it all in to the equations
