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.
What must occur in a linear inequality when you divide or multiply by a negative number?
The inequality sign must be flipped.
What is a mathematical phrase that has numbers and operation signs but no equals sign?
if there are no comparison signs (equals or inequalities, ie =, >, < etc) then it is an expression, eg "x + 5" If there is a comparison sign which is not equals, then it is an inequality, eg "x > 5"
What do you need to do to the inequality sign if you multiply or divide both sides of an inequality by a negative number?
Leave it alone. You cannot make an inequality into an equality by multiplying both sides of the inequation by the same number. If instead of the inequality sign you are using a lesser or greater than sign, however, you will need to reverse it if you multiply both sides by the same negative number, e.g. 10>4. If you multiply both sides by -2, you need to change the > into a <, so -20<-8
Difference between sign in and signup?
sign up means to join a new website when you are not a member of that site. but sign in means to open a website when you are already a member of it.. for example : to create a yahoo account, you click on sign up but to check your account you click on sign in.....

What is a solution to the inequality x281?
"x281" is an expression, not an inequality. An inequality is supposed to have an inequality sign, such as "<" or ">".
When is the only time you flip an inequality sign?
When you divide both sides of an inequality by a negative number, the inequality sign flips.
What is the inequality of 13 X plus 2665?
There is no inequality since there is no inequality sign.
When graphing a linear inequality the first step is to replace the inequality symbol with what sign?
With the equal sign (=).
Do you flip the inequality sign if the only the variable is negative?
No, you only flip the inequality sign if you are dividing by a negative number on both sides of the inequality
When you must reverse the inequality sign?
When solving an inequality, you must revers the inequality sign when you multiply (or divide) both sides by a negative number.
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.
