What does a filled in circle on a number line mean?

less than or equal to
A filled circle is used for “less than or equal to” and for “greater than or equal to”. An open circle is used for “less than” and for “greater than”. FYI…

What is a filled in circle?

When talking about circles, a “circle” refers merely to a line in the shape of a circle, whereas “disk” (or “disc”) refers to a “filled circle”.

Which inequality has an open circle when it is graphed on a number line?

When graphing a linear inequality on a number line, use an open circle for “less than” or “greater than”, and a closed circle for “less than or equal to” or “greater than or equal to”. To CHECK an inequaltiy, it is not possible to test every value.

Is empty circle on or off?

IEC 60417-5008, the power-off symbol (circle) on a button or toggle, indicates that using the control will disconnect power to the device. (0 or ◯ means off.) IEC 60417-5009, the standby symbol (line partially within a broken circle), indicates a sleep mode or low power state.

Is circle filled?

When talking about circles, a “circle” refers merely to a line in the shape of a circle, whereas “disk” (or “disc”) refers to a “filled circle”. Is there a similar distinction for squares or rectangles?

What do open circles on a graph mean?

Explanation: An open circle indictes “less than” or “greater than,” while a closed circle indicates “greater than or equal to” or “less than or equal to”.

How do you represent the inequality in the number line?

Let us represent the given inequality in the number line. Since the given inequality x ≤ 7 (less than or equal), so we draw the line left side from 7 with a filled circle on the number line. Since the given inequality x > 8 (greater than), so we draw the line right side from 8 with an unfilled circle on the number line.

Do you fill in the circle if you’re only less than 500?

Notice, if we’re including 1,500, we fill in the circle. If we’re not including 1,500, so we’re only less than, we were very explicit that we don’t color in the circle. But then we show that, look, we can do everything below that.

Which inequality requires an open circle at 3 and an arrow?

The first inequality, y>3, will require an open circle at 3 and an arrow pointing right. The other inequality, y<-2, will require an open circle at -2 and an arrow pointing left. Question 4: Display the inequality -1\\leq x \\leq8 on a number line.

What is a circle on a number line?

The circle is the end point of the line. If a circle is filled, then it is equal to or greater/less than the fixed value. If the circle is not filled, then the fixed value is not included. Two inequalities can be applied to a value at the same time. On a number line, this would be represented by a line with a circle at each end.
