5x-9=1 solve for x thanks

Step-by-step explanation:

We know that 5 times x has to be greater than 9, since the equation's outcome is not negative.  We know that 1 + 9 = 10, so 5 times x must equal 10.    

5 x 2 = 10

5 x 2 - 9 = 1

Therefore, x = 2

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.
