Evaluate each expression when y=5.

B. 4(y+3)

B. 4(y+3)=4(5+3)=4×8=32

32

Step-by-step explanation:

Step 1: Sub y = 5 into the expression

Find anywhere that has a 'y' and replace it with a 5

4(y+3)

4(5+3)

Step 2: Solve

Use BEDMAS to solve the expression

4(5 + 3)

4(8)

32

Step 3: Therefore Statement

Therefore the expression is equal to 32

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.
