Answer:
1/3x=y-3, y=2/3x
Step-by-step explanation:
1/3x=y-3 is a linear function because there are no powers.
y=x^3+2 is not a linear function because x is squared by 3.
y=6x^2 is not a linear function because x is squared by 2.
y=2/3x is a linear function because there are no powers.

Make the bottom number the same to find the increase
find the increase
from 1/2 to 7/10
1/2 times 5/5=5/10
from 5/10 to 7/10 is 2/10 or 1/5 increase
3 gallons was added
so 3 gallons=1/5 of the container
times 5/1 both sides
15 gallons=5/5 of the container
the container can hold 15 gallons of water
Answer:
The coefficient is 7
Step-by-step explanation:
The coefficient of an algebraic expression is the number that is being multiplied by a variable or multiple variables. In this case, 7 is being multiplied by x and y, so 7 is the coefficient.
They drank 9 liters of punch. Because you started out with 12, and you had 3 left, you subtract 3 from 12 to get how many your drank. So, 12-3=9
