What is the value of the y-coordinate of the solution to the system of equations 2y=9-x and x=y+3

5

Step-by-step explanation:

2Y=9-X          X=Y+3

Y=(9-X)/2          X=(9-X)/3+3

                         X=15/3

                         X=5

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

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.
