To which subsets of real numbers does the number -22 belong?
whole numbers
rational numbers
integers
irrational numbers
natural numbers

A -22 can be a rational number as well as a integer

Step-by-step explanation:

Whole Number: A whole number is not a fraction or a decimal so a example would be: 43 or 85 or 1 or 3. Zero is not a whole number. Negative are not whole numbers

Rational number: A rational number is a number that can be expressed as a fraction or a decimal. Like 33 can be 33/1. Most numbers are rational. Zero is a rational number.

Integers: A integer is not a fraction or a decimal. its a positive or negative number. Example: 1 or -5 or 85 or -445. there is still some arguments about if zero is a integer.

Irrational numbers: A irrational number cannot be expressed as a ratio. So for example pi: 3.141592653589(it keeps on going, we haven't even gotten to the end because its infinite).

Natural numbers: Natural numbers are positive numbers. Example: 1,6,3,4,62,3 etc. Sometimes zero is a natural number.

The sum of the polynomials is -11x - 3y^2.

In order to find this we must first collect all like terms. To start, we'll begin with all x^2 terms.

8x^2 - 9x^2 + x^2 = 0

Since these all cancel, we're left with no x^2 term. Next we'll do x terms.

-4x - 7x = -11x

The only thing left is -3y^2, which has no alike term. so we just include that in there.

-11x - 3y^2
