What is the value of x in the equation -6 + x = -1?

x = 5

Step-by-step explanation:

Get x by itself

-6 + x = -1

Add -6 to both sides to get x alone.

-6 + x = -1

+6        +6

x =  5

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.
