Display the interval notation for:
25a<9.50
Interval Notation Definition:
An interval as a set of numbers.
Numbers = endpoints.
Build interval notation
We get interval notation by saying 25a<9.50
Since our variable of a has a coefficient of 25
Divide each side of the inequality by 25
| 25a | |
| 25 |
| < |
| 9.50 |
| 25 |
a<0.38 ←Use this expression going forward
Inequality Sign Evaluation
You entered the < sign
Build the interval notation for a:
No equal sign translates to ).
Do not include the number 0.38
Based on the < you entered,
the left side of the interval notation will extend to negative infinity,
which is denoted as -∞
Final Answer
(-∞,0.38)
Set Builder Notation for a:
{ a | a<0.38 } where | denotes such that
