Which expression would be easier to substitute into the other equation, in order to solve this problem? explain your reasoning.
x=3y-2
x+3y=4

x=3y-2 substitute is easier to solve the equation

Step-by-step explanation:

given x=3y-2(1)

x+3y=4(2)

put x=3y-2 in equation (2)

3y-2+3y=4

6y-2=4

+2

6y=6

y=1

x=3y-2

x=3(1)-2=1

x=3y-2 substitute is easier to solve the equation answer

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.
