Question
The following number line graph represents ________________ inequality.
- x ≥ 3
- x > 3
- x < -3
- x ≤ 3
Hint:
A mathematical representation of relationship between 2 or more variables or a variable and a constant wherein the relationship is not equal. i.e. greater than/ greater than or equal to/ less than/ less than or equal to. is known as inequality.
The correct answer is: x ≥ 3
TO FIND-
Inequality that represents the given situation.
SOLUTION-
Let x be the variable that is represented on the given number line.
From the given graph, we observe that x assumes the following values-
x = 3, x = 4, x = 5, x = 6,........................
Hence, x assumes values that are greater than or equal to 3.
Hence, x >= 3.
Final Answer:-
Option 'd' i.e. 'x >= 3' is the correct answer to the given question.
Since portion for 3 is shaded on the number line, 3 is included in the inequation. i.e. 3 is a solution to the given inequality.
Hence, we take x >= 3 and not x > 3.
