I dunno an who cares!
we use closed circles when we include the number on which it is and if we dont want to include it then we use open circle

How do you know whether to use an open circle or a closed circle when graphing an inequality and why?
An open or closed circle are used to graph an inequality in one variable. An open circle is used if the value at the end point is excluded from the feasible region while a closed circle is used if the value at that point is within the accepted region.
When graphing an inequality with one variablehow do you graph less than or greater than problem?
Arrange the inequality so that the variable is on the left. ex x < 7 If not equal to put an open circle at the number (7 in my example) if less than shade the number line to the left ( less than = shade left) if greater than shade right. If equal to put a point ( shaded dot) on the number follow same rules for shading
How do you graph -6 is greater than x plus 5 as an inequality on a number graph?
The inequality -6 > x+5 can be rewritten -11 > x (by subtracting five from each side) or rather x < -11. To graph this on a number line, draw an open circle over the number -11 (if the inequality included "or equal to" the circle would be filled in). Then draw a line/arrow coming out of the circle over the number line. The line should only be drawn over the portion of the number line that makes the inequality true. For instance, choose a test point. When x is -20, the inequality is true: -20 < -11. So in this case, the arrow coming out of the open circle will point to the left, in the direction that the number line is getting smaller.
How do you answer a inequalities on a number line?
x>2, you use an open circle above the #2 and shade to the right. If the equation was greater than or equal to 2, you would use a closed circle and shade to the right! Less than 2 would use the open circle to not include 2 and you would shade all numbers to the left of 2. Less than or equal to 2, solid circle which includes #2 and shade all #'s to the left of 2!
What is an open figure?
an open figure is a polygon that is not completely closed.
How do you know whether to use an open circle or a closed circle when graphing an inequality?
If the inequality is > or< then it is an open circle. If it is greater than or equal to or less than or equal to, it is a closed circle.

An open or closed circle are used to graph an inequality in one variable. An open circle is used if the value at the end point is excluded from the feasible region while a closed circle is used if the value at that point is within the accepted region.
Which do you use an open circle or closed cirle for graphing inequalities?
A closed circle is when a range of numbers also includes that number and an open circle is when a range of numbers doesn't include that number, :)
How will you decide when to use an open circle or close circle when graphing?
we use open circle
What inequaity do you use open circle?
A strict inequality.
How do you know whether to use a open circle or a closed circle?
If points on the circumference are excluded from the locus then an open circle, else a closed one.
Is a circle closed figure or open figure?
closed figure
How do open and closed circles relate to solid and dashed lines?
An open circle should have a dashed circumference, a closed circle a solid one.
How do you know when to have an open circle or a closed circle at a line segment?
If the value at the end is not included (< or >) then it should be an open circle. If the value at the end isincluded (≤ or ≥) then it should be a closed circle.
What is the difference of an Open and closed circle number line?
With an open circle, the number at which the circle is is NOT included in the dataset; with a closed circle it is. For example if a line is drawn on the number line between 0.5 and 1.5 with a closed circle at 0.5 and an open circle at 1.5, then it represents the numbers between 0.5 and 1.5 including 0.5 but excluding 1.5; this range is the numbers which round to 1 to the nearest whole number.
When the variable is on the left of the inequality symbol is represented by an open circle and a ray going to the right?
how the hell should i know
How can you graph an inequality?
You have to graph an inequality on a number line. For example, x>3.The number 3 on the number line gets an open circle around it, and a line is extended to all the other possible equations.There is an open circle if it is a "greater than or less than" sign, and there is a shaded circle if there is "greater than or equal to, or a less than or equal to" sign.
