Display the interval notation for:
150p≤3000
An interval as a set of numbers.
Numbers = endpoints.
We get interval notation by saying 150p≤3000
Since our variable of p has a coefficient of 150
Divide each side of the inequality by 150
150p | |
150 |
≤ |
3000 |
150 |
p≤20 ←Use this expression going forward
Inequality Sign Evaluation
You entered the ≤ sign
Because you entered an equal sign
Translate to ] since we include the number 20
Based on the ≤ you entered,
the left side of the interval notation will extend to negative infinity,
which is denoted as -∞
{ p | p≤20 } where | denotes such that
∞,...,10,11,12,13,14,15,16,17,18,19,20
