Solve above question​

x=-2.5,y=7.5

Step-by-step explanation:

Solution,

3x+y=2(1)

x+y=7

or,y=7-x(2)

Now,by putting the value of y from equation 2 to equation 1,we get

3x+y=2

or,3x+(7-x)=2

or,3x+7-x=2

or,2x+7=2

or,2x=2-7

or,2x=-5

or,x=-5/3

or,x=-2.5

Again,

by putting the value of x in equation 2,we get

x+y=7

or,-2.5+y=7

or,y=7+2.5

or,y=7.5

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

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.
