A lawn mower has the given energy rating. A full tank of gas can power the lawn mower for about 6 hours. What equation can be
used to find the amount of gas left in the tank, y, as a function of
the mowing time, x? Show your work.

the answer is 15% decrease

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
