Answer:
See below.
Step-by-step explanation:
The set of all real numbers except for 100 in set builder notation (assuming the variable is x) is:
[tex]\{x|x\in\mathbb{R},x\neq100\}[/tex]
The very first x represents the variable.
The second with the R represents the number. Here, we want all real numbers.
And the third is the constraint. We want all real numbers except for 100.
