Question

Which description is correct for the set of all real numbers less than -5​

Answer 1

`x | x \in R \text { and } x<-5` is the correct description for the set of all numbers less than -5

Solution:

We have to find the correct description for the set of all numbers less than -5

Let "x" be the set of all numbers less than -5

So the correct description is:

`x | x \in R \text { and } x<-5`

Here , "R" represents real numbers. i.e real numbers less than -5

A real number is any element of the set R, which is the union of the set of rational numbers and the set of irrational numbers

Positive or negative, large or small, whole numbers or decimal numbers are all Real Numbers

So the description is "x" belongs to real numbers which are less than -5
