An interval as a set of numbers. Numbers = endpoints.
Build interval notation
We get interval notation by saying 7.5h<120
Since our variable of h has a coefficient of 7.5 Divide each side of the inequality by 7.5
7.5h
7.5
<
120
7.5
h<16 ←Use this expression going forward
Inequality Sign Evaluation
You entered the < sign
Build the interval notation for h:
No equal sign translates to ). Do not include the number 16
Based on the < you entered, the left side of the interval notation will extend to negative infinity, which is denoted as -∞
Build notation
(-∞,16)
You have 2 free calculationss remaining
Set Builder Notation for h:
{ h | h<16 } where | denotes such that
Display the literal notation for h

What is the Answer?
(-∞,16)
