Question

Write the interval (5, 100] as an inequality and using set notation

Answer 1

The interval in inequality notation would be written as:
5(less than) x (less than or equal to) 100
I have attached an image as well so it is easier to read. 
I hope this helps (:

Answer 2

Answer with explanation:

Inequality--

To represent the interval form in the form of a inequality we need to use the signs such as greater than , less than , equal to , greater than or equal to and less than or equal to.

Set notation--

Set notation is used to define the elements of a set.

The interval form is as follows:

           (5,100]

• The inequality form is:

              5 < x ≤ 100

• and the set notation is given by:

   S={x∈ R | 5 < x ≤ 100 }
