Step-by-step explanation:

One method could be rewriting the second equation as x in terms of y and solving by replacing in the first equation.

Replace...

add on both sides.

Combine like terms

Now, to get rid of the fraction and isolate y, multiply by the reciprocal or the inverted fraction.

Simplify

Now replace the value of y in either equation to find x.

add 56

Divide by 9

To check whether these values are accurate, replace in either equation both values and you should have an equality. In this case I'll do it in both equations.

1/2*qr*rs

step-by-step explanation:

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.
