The Math Problem
The constant is -4, beacuase it never ever changes and will aalways stay the same. A constant is a variable that never changes
The Independent Variable
The independent variable is the weeks, because it does not rely on any other variable and will not change becuase of another An independent variable is a variable that depends on nothing.
The Dependent Variable
The dependent variable is the water level, because the water level depend's on the weeks(the Independent variable) and the amount of water it loses every week ( The constant -4). A Dependent variable is a variable that depends on the independent variable and the constant.
This is the correct and accurate (Its drawn, so its a not perfect) because the water level (in blue) is decreasing steadily over time as they water dries up.
64-(7x4) solve the problem in parenthesis
64-28 solve the problem
After 7 weeks the water will be at 36 feet. The lake lost 36 feet
