The perimeter of dawna's new flat screen television is 112 inches. the ratio of its length to width is 4: 3. write and solve an algebraic equation to determine the dimensions of the television.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

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.
