To 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. Choose two options.

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.

For this we will analyze each statement:

A.) g is the dependent variable - This one is correct because it will depend on the value of u.

B.) u is the dependent variable. - This one is wrong because u is the independent variable.

C) u is the independent variable. - This one is correct because you can give the value to u and in return you can get value of g.

D.) the variables cannot be labeled without a table of values. - This statement is wrong   you can look for for the answer in the above statements.

E.) the variables cannot be labeled since any value can be selected for either. - This statement is also wrong.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
