Bill’s car gets 30 miles to the gallon. For every gallon of gas it consumes, his car runs 30 miles. Use this information to determine whether this relation is a function.

Write the equation for the number of miles Bill travels, y, in terms of how much gas it uses, x

It is a function.

Step-by-step explanation:

Examples:

y5 = x5

y6 = x6

Part a: Bill’s car travels 30 miles per gallon of gas. If y represents the number of miles the car travels on x gallons of gas, the equation that represents this situation is y = 30x.

Part b:       gallons of gas (x)miles (y)

                                     1          30

                                     2  60

                                     3  90

Part c: There is no x-value that would lead to multiple y-values.

Part d: Yes, y = 30x is a function, because for every input, or x-value, there is only one output, or y-value.

edmentum answer (:

so far i think you have the right thing going for you just remember soh cah toh
