What inequality is represented on this number line?
Note: In a number line, a closed circle on the number gets included in the solution, while an open circle on the number will not get included in the solution.
There is a closed––––––– circle at 1 and the line goes to the right side representing the numbers greater than or equal to 1.
It can be represented mathematically as:
⇒x≥1 which can also be written as 1≤x (writing x on the right hand side)
There is also an open circle at 4 and the line goes to the left side representing the numbers lesser than or equal to 4.
It can be represented mathematically as:
⇒x<4
Hence, The line between these two points means that x satisfies both inequalities, so a double inequality must be created.
⇒1≤x and x<4
Combining the above two inequalities, we get 1≤x<4
Hence, x is greater than or equal to 1 and x is less than 4.
