Plz help me!! i really need it. will mark brainliest

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

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.
