For the formula x = 3y - z, what is the value of x when y = 4 and z = 1?

here, x=3y-z then,

(substitute value of y and z)

x=3×4-1

=12-1

x=11ans

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.
