greater than or equal to n > 15 what would it look like on a graph closed or open circle on graph bar

Answer 1

When graphing the inequality n > 15, you would typically use a number line to represent all possible values of n. Since n > 15 means that n can be any number greater than 15—but not equal to 15 itself—you would use an open circle at the point where 15 is located on the number line. An open circle indicates that the point at which it's placed is not included in the set of solutions for the inequality.

Here's how you would draw it:

1. Draw a horizontal number line.
2. Mark the point corresponding to 15 on this number line.
3. Place an open circle around the 15 mark to show that 15 is not included.
4. Draw a line or arrow extending from the open circle to the right, towards the larger numbers, to represent all numbers greater than 15.

If the inequality were greater than or equal to (n ≥ 15), then you would use a closed circle at 15 to indicate that 15 is included in the set of solutions, and again extend a line or arrow to the right showing all the numbers greater than or equal to 15 are also solutions.
