Display the interval notation for:
5p≤35
Interval Notation Definition:
An interval as a set of numbers.
Numbers = endpoints.
Build interval notation
We get interval notation by saying 5p≤35
Since our variable of p has a coefficient of 5
Divide each side of the inequality by 5
| 5p | |
| 5 |
| ≤ |
| 35 |
| 5 |
p≤7 ←Use this expression going forward
Inequality Sign Evaluation
You entered the ≤ sign
Build the interval notation for p:
Because you entered an equal sign
Translate to ] since we include the number 7
Based on the ≤ you entered,
the left side of the interval notation will extend to negative infinity,
which is denoted as -∞
Final Answer
(-∞,7]
Set Builder Notation for p:
{ p | p≤7 } where | denotes such that
