What else can I help you with?
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.
What inequality has 3 and negative 5 as two of its solutions?
x+7 is greater than or equal to 2
Which inequality has x0.8 as one of its solutions?
One possible inequality that has x = 0.8 as a solution is x ≤ 0.8. This means that any value of x that is less than or equal to 0.8 will satisfy the inequality.
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.
Which values are solutions to the inequality x2 is more than or equal to 11?
x ≤ -sqrt(11) or x ≥ sqrt(11)
Is there ever a time when the same value will be a solution for both the equation and the inequality?
Yes, but only when the inequality is not a strict inequality: thatis to say it is a "less than or equal to" or "more than or equal to" inequality. In such cases, the solution to the "or equal to" aspect will satisfy the corresponding inequality.
What is a comparison of two expressions that are not equal?
an inequality
Which are the solutions to the inequality square root of x is less than or equal 7?
+sqrt(7) = 2.6457 (approx) so the solution is-2.6457 < x < 2.6457
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.
Is xl7.6x7.0 an inequality?
No. To be an inequality, it must somewhere have a greater than, less than, greater-or-equal, or less-or-equal sign.
Is 4n9 an example of an inequality?
No. An inequality will show two expressions that aren't equal.
What is an expression with no equal sighn?
An inequality.
