Which expression is equivalent to 2(m − 4) + 1? (1 point)
2m − 7
2m − 3
2m + 9
2m + 10

The expression  2(m − 4) + 1 is equivalent to 2m - 7 .

Step-by-step explanation:

As the expression given in the question is as follows

=  2(m − 4) + 1

Now first open the bracket of the above experession

= 2m - 8 + 1

Simplify the above

= 2m - 7

Therefore the expression  2(m − 4) + 1 is equivalent to 2m - 7 .

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.
