which best proves why the expressions 4(x+3)+2x and 6(x+2) must be equivalent expressions?
when x-3, both expressions have a value of 30.
when x-5, both expressions have a value of 42.
when x= 1, both expressions have a value of 18, and when x=8, both expressions have a value of 60.
when x = 2, both expressions have a value of 15, and when x=6, both expressions have a value of 39.

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.

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
