PLEASE HELP ME!!

Consider that x = −5 and y = −4. Which statement is true about x + y?
A) The sum of x and y is a rational number.
B) The sum of x and y is an imaginary number.
C) The sum of x and y is an irrational number.
D) The sum of x and y is neither rational nor irrational.

Answer 1

Option A) The sum of x and y is a rational number

Explanation:

we know that

A rational number is a number that can be written as a ratio or quotient of two integers

so

In this problem we have

`x=-5, y=-4`

`x+y=-5-4=-9`

Is a rational number, because the number
`-9` can be written as a ratio or quotient of two integers

Example

`-(27)/(3)=-9`

`-(9)/(1)=-9`
