An interval as a set of numbers. Numbers = endpoints.
Since our variable of p has a coefficient of 150 Divide each side of the inequality by 150
150p

≤
3000
150
p≤20 ←Use this expression going forward
You entered the ≤ sign Start on the right side of p<=20
Build the interval notation for p:
An equal sign translates to ] Include the number 20. The left side extends to -∞
(-∞,20]
Set Builder Notation for p:
{ p | p≤20 } where | denotes such that
Display the literal notation for p
∞,...,10,11,12,13,14,15,16,17,18,19,20
What is the Answer?
(-∞,20]
How does the Interval Notation and Set Builder Notation Calculator work?
Free Interval Notation and Set Builder Notation Calculator - This calculator translates the following inequality statements to interval notation and set builder notation:
* x < 5
* y <= 5
* z > 5
* a >= 5
* b < 5 or b > 20
* Compound Inequality such as 0 <= c < 4
* |x|<3
* Reverse Interval Notation to Inequality Statement such as (-7,5]
* {x|x<1}
* Word representations of interval notations such as 2 is less than or equal to x is less than or equal to 8 This calculator has 2 inputs.
