The value of y varies directly with x, and y = 18 when x = 12. find y when x = 132. y = 78 y = 88 y = 198 y = 1.5 !

y = 198

Step-by-step explanation:

y varies directly as x means that:

y = kx

We don't know that constant (k) yet.

Now, we plug in the values of x and y, y=18 when x=12.

y = kx

18 = 12k

k = 18/12

k = 1.5

Now,we rewrite the equation with the value of k.

y = 1.5x

To find y when x = 132

y= 1.5x

y = (1.5 × 132)

y = 198

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.
