Fernanda Morse · Answer 1

2. A function has two or more variables. Those whose values do not depend on anything are called the independent variables and those whose values depend on other factors are the dependent variables. The answer to this is letter D.

3. The total charge is the sum of the initial charge, $10, and the charge that is dependent on the number of square foot lawn. The answer is therefore,

y = 10 + 0.15x

This is letter B.
