Is (2,2) a solution of y≤4x−6 ?

yes

Step-by-step explanation:

fill in x and y  

then simplify

this is true because 2 is less than or equal to 2

To find out if (2, 2) is a solution, substitute/plug the point into the inequality:

y ≤ 4x - 6    

2 ≤ 4(2) - 6

2 ≤ 8 - 6

2 ≤ 2    

2 is equal to 2, so (2, 2) is a solution for this inequality

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.
