Why is graphing the solutions of an inequality is more efficient than listing all the solutions of the inequality?
because writing out all the solutions is not necessarliy a correct answer but a number line is and because graphing out also helps you get a mental image of the concept.
What is the equation called when you use greater than less than or equal to?
This is called an inequality.
What is inequality in algebric equation?
An inequality is similar to an equation, in that it compares two expressions. But in an equality, instead of an equal sign, you would usually use one out of the following inequality symbols:* less than * less than or equal * greater than * greater than or equal
What does inequality mean in math terms?
An inequality is similar to an equation, except that instead of an equal sign, it uses one of the following signs: * less-than * less-than-or-equal * greater-than * greater-than-or-equal
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.
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 is an equation different from an inequality?
In an equation, what is to the left of the equals sign equals what is to the right. In an inequality, the left side is either less than, greater than, less than or equal to, or greater than or equal to the right side.
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. (<, >)
Is a number an expression equation or inequality?
A number is an expression. It is not an equation, or an inequality, since it doesn't have an equal sign, or an inequality (greater than, less than, etc.) sign.
Why is graphing the solutions of an inequality is more efficient than listing all the solutions of the inequality?
because writing out all the solutions is not necessarliy a correct answer but a number line is and because graphing out also helps you get a mental image of the concept.
When graphing inequalities when do you shand upward and when do you shade downward?
Shade upward if the inequality involves a "greater than" comparison. Shade downward if the inequality involves a "less than" comparison.
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.
In what way is an inequality different from an equation?
In that it uses an inequality sign (less then, greater than, less-than-or-equal, greater-than-or-equal) instead of an equality sign. When solving, special care must be taken - when multiplying or dividing both sides of an inequality by a negative number, the direction of the inequality sign changes.
Is a number increased by 10 is 24 an equation or an inequality?
The word "is" implies equality - an equation. An equality would be expressed different, for example, "is more than", "is at least", etc.
Is 3x 114 an equation or an inequality?
3x = 114 is an equation because it states that two expressions are equal to each other, whereas an inequality would involve a greater than, less than, greater than or equal to, or less than or equal to sign.
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.
If you replace the equal sign of an equation an put an inequality sign in its place is there ever a time when the same value will be a solution to both the equation and inequality?
Yes, when the inequality has a less that or equal to sign, or a greater than sign or equal to sign, then the equal sign can be replaced and get a solution that is common to both the equation and the inequality. There can also be other solutions to the inequality, where as the solution for the equation will be a valid one.
