The numbers are given to be:
[tex](-\infty,-5)[/tex]
This is written in Interval notation.
In "Interval Notation" we just write the beginning and ending numbers of the interval, and use:
a) [ ] a square bracket when we want to include the end value, or
b) ( ) a round bracket when we don't.
Because the interval given uses round brackets, the inequality will contain all real numbers between negative infinity and -5, but not including negative infinity and -5.
Therefore, the inequality will be:
[tex]-\infty
