Obill 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.

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

Step-by-step explanation:

We are given equation , 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.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
