##### Enter inequality for interval notation:

Display the interval notation for:

9j>36

##### Interval Notation Definition:

An interval as a set of numbers.
Numbers = endpoints.

##### Build interval notation

We get interval notation by saying 9j>36

Since our variable of j has a coefficient of 9
Divide each side of the inequality by 9

 9j 9
 >
 36 9

j>4  ←Use this expression going forward

##### Inequality Sign Evaluation

You entered the > sign

##### Build the interval notation for j:

No equal sign translates to (.
Do not include the number 4

Based on the > you entered,
the right side of the interval notation will extend to positive infinity,
which is denoted as +∞

(4,+∞)

##### Set Builder Notation for j:

{ j | j>4 } where | denotes such that

##### Display the literal notation for j

5,6,7,8,9,10,11,12,13,14,...,∞

(4,+∞)
