To determine which statements about the relationship between gallons of water used (g) and the number of units (u) are true, we need to understand the meaning of independent and dependent variables in the context of the given equation \( u = 748g \).
1. **Independent Variable**: This is the variable that is controlled or manipulated. In this case, it's the number of gallons of water used (g) because it is the input value.
2. **Dependent Variable**: This is the variable that changes in response to the independent variable. In this case, it's the number of units (u) because it depends on the number of gallons used.
Therefore, the correct statements are:
- u is the dependent variable.
- g is the independent variable.
These choices correctly reflect the relationship where the number of units (u) depends on the gallons of water used (g).
So, the two true statements are:
- **u is the dependent variable.**
- **g is the independent variable.**
To bill customers for water usage, one city converts the number of gallons used into units. This relationship is represented by the equation u = 748g, 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.
