When will the graph of an equation inequality be a dotted line?
The line is dotted when the inequality is a strict inequality, ie it is either "less than" (<) or "greater than" (>). If there is an equality in the inequality, ie "less than or equal to" (≤), "greater than or equal to" (≥) or "equal to" (=) then the line is drawn as a solid line.
Explain when to use a solid line as a boundary when graphing a linear in equality?
you use a solid line when the inequality is less than or equal to or greater that or equal to the dotted line is for less than or greater than
What inequality is greater than or equal to -5?
An inequality has no magnitude. A number can be greater than or equal to -5, but not an inequality.
What is a comparison of two expressions that are not equal?
an inequality
How do you determine whether to use a solid or dashed line when graphing linear equation?
A dashed line is used when the equality is equal to and less than/more than. (≤, ≥) A solid line is used when the inequality is just less than/more than. (<, >)
When graphing a linear inequality the first step is to replace the inequality symbol with what sign?
With the equal sign (=).
Ask us graphing a linear inequality the first step is to replace the inequality symbol with a(n) sign.?
When graphing a linear inequality, the first step is to replace the inequality symbol with an equal sign to graph the corresponding linear equation. This creates a boundary line, which can be solid (for ≤ or ≥) or dashed (for < or >) depending on whether the points on the line are included in the solution set. After graphing the line, you then determine which side of the line represents the solution set by testing a point (usually the origin if it's not on the line) to see if it satisfies the original inequality. Finally, shade the appropriate region to indicate the solutions to the inequality.
How is graphing a linear inequality different than graphing a linear equation?
In an inequality, you have to shade a side of a line to see show if the possible answers are greater than or equal to it
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.
What is the math symbol for is at most?
The inequality symbol for less than or equal to: ≤
What is the equal to or greater then symbol on a graph?
If the graph is a two-dimensional plane and you are graphing an inequality, the "greater than or equal to" part will be shown by two things: (1) a solid, not a dotted, line--this part signifies the "or equal to" option--and (2) which region you shade. Shade the region that contains the points that make the inequality true. By shading that region, you are demonstrating the "greater than" part.
When will the graph of an equation inequality be a dotted line?
The line is dotted when the inequality is a strict inequality, ie it is either "less than" (<) or "greater than" (>). If there is an equality in the inequality, ie "less than or equal to" (≤), "greater than or equal to" (≥) or "equal to" (=) then the line is drawn as a solid line.
How does an inequality symbol act differently than an equal symbol?
An inequality is not a reflexive relationship.
What does a dashed boundary line indicate when graphing linear inequalities?
It means that the inequality is less than the value of the dashed line and is not equal to it.
When graphing a linear inequality the first step is to replace the inequality symbol?
Well, you can replace the inequality with the equal sign, and draw the line (or curve, depending on the case) for the corresponding equation. The actual inequality will be either to one side or to one side of this line or curve. It may or may not include the actual line or curve.
What is a number x is at most -10?
If you want that as an inequality, you write:x <= -10 You can replace "<=" with the corresponding inequality symbol (less than or equal).
Which inequality symbol represents the statement No more than?
The inequality symbol that represents the statement "no more than" is "≤" (less than or equal to). This symbol indicates that a value can be equal to or less than a specified limit. For example, if a variable ( x ) is described as "no more than 10," it can be expressed as ( x ≤ 10 ).
