WebWhen we graph an inequality on a number line we use open and closed circles to represent the number. The open circle means the number is not included in the solution X>5 means that whatever value x has, it must be greater than 5. The open dot shows that 5 is not a solution. Numbers greater than 5 are to the right of 5 on the number line. WebInequalities can be shown on a number line. Open circles are used for numbers that are less than or greater than (< or >). Closed circles are used for numbers that are less than or equal to and... dhc collagen beauty 7000
What do open and closed circles mean in inequalities?
WebDecide if it needs an open circle or a closed circle; < or > would need an open circle \leq or \geq would need a closed circle. Indicate the solution set with a straight line to the left hand side or right hand side of the number or with a straight line between the circles. E.g. Represent x < 3 on a number line. An open circle needs to be ... WebEach of these graphs begins with a circle—either an open or closed (shaded) circle. This point is often called the end point of the solution. A closed, or shaded, circle is used to represent the inequalities greater than or equal to [latex] \displaystyle \left(\geq\right) [/latex] or less than or equal to [latex] \displaystyle \left(\leq\right) [/latex]. WebWe will also study techniques for solving and graphing inequalities having one unknown.
