Use an alternative method to express the following set: {y:y is a person in your math class and also more than 100 years old.}

Sagot :

Let's use the letter M to label the math class. The fact that person y is in that class can be expressed by:

[tex]y\in M[/tex]

We also have to show that is older than 100 so we have:

[tex]y>100[/tex]

If we put all this information together we get:

[tex]\mleft\lbrace y\colon y\in M,y>100\mright\rbrace[/tex]

And that's an alternative way to express the set.
