This relationship is represented by the equation g=748u, where g is the total number of gallons of water used and u is the number of units. Determine which statements about the relationship are true. Check all that apply.

A.) g is the dependent variable.

B.) u is the dependent variable.

C.) u is the independent variable.

D.) the variables cannot be labeled without a table of values.

E.) the variables cannot be labeled since any value can be selected for either.

Respuesta :

The answer to this question would be: 
B.) u is the dependent variable. 

In this case, the gallon is converted into unit which means the number of gallons is fixed(got from the customer water usage) but the number of units depends on the number of the gallon(748unit for every gallon). That is why "unit" become the dependent variable and "gallon" become the independent variable.

The answer are:

B and C only
