7x
Display the interval notation for:
7x≤21
Interval Notation Definition:
An interval as a set of numbers.
Numbers = endpoints.
Build interval notation
We get interval notation by saying 7x≤21
Since our variable of x has a coefficient of 7
Divide each side of the inequality by 7
x≤3 ←Use this expression going forward
Inequality Sign Evaluation
You entered the ≤ sign
Build the interval notation for x:
Because you entered an equal sign
Translate to ] since we include the number 3
Based on the ≤ you entered,
the left side of the interval notation will extend to negative infinity,
which is denoted as -∞
Build notation
(-∞,3]
You have 1 free calculations remaining
Set Builder Notation for x:
{ x | x≤3 } where | denotes such that
Display the literal notation for x
