Question

o bill customers for water usage, one city converts the number of gallons used into units. 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. g is the dependent variable. u is the dependent variable. g is the independent variable. u is the independent variable. The two variables cannot be labeled as independent or dependent without a table of values. The two variables cannot be labeled as independent or dependent since any value can be selected for either.

Answer 1

U is the independent variable and G is the dependent variable because g depends on how much u there is.

Answer 2

g is the dependent variable; and u is the independent variable.

Explanation:

We are given equation
`g=748u`, where g is the total number of gallons of water used and u is the number of units.

Now, the number of units of water does not depend on the total number of gallons of water used. Now u is the variable that causes g to change.

So, u is an independent variable.

But the total number of gallons depends on the number of units used. As when more gallons are used, more units will be generated.

Therefore, g is a dependent variable.
