How do you know when to reverse the direction of an inequality symbol?
u only reverse the sign when u multiply or divide by a NEGATIVE number...otherwise u don't change the direction
What is the comparison symbol of 4 1?
The inequality symbol.
What is the math symbol for is at most?
The inequality symbol for less than or equal to: ≤
If you multiply or divide both sides of an inequality by a number you need to reverse the inequality sign?
negative flip
Who invented strict inequality symbol?
my dad
If you multiply an inequality by a negative number when should you reverse the inequality symbol?
Always.
Algebra why is it necessary to reverse the inequality symbol when multiplying both sides of an inequality by a negative number?
Because your multiping the inverse to both sides
How do you know when to reverse the direction of an inequality symbol?
u only reverse the sign when u multiply or divide by a NEGATIVE number...otherwise u don't change the direction
Why it is necessary to reverse the inequality symbol when multiplying both side of an inequality by a negative number?
You need to reverse the inequality symbol when multiplying both sides of an inequality by a negative number because you are changing the sign of both sides of the equation. Since inequality, such as "less than", means "to the left of" on the number line (where left is minus and right is plus) then a number that is less than another will be greater than the other if the signs were reversed. Example: 3 is less than 4, but -3 is greater than -4.
When you divide both sides of an inequality by a negative number you need to blank the inequality symbol?
Flip. You need to reverse the inequality when multiplying or dividing by a negative. -2x < 10 (-1)*(-2x) < (-1)*10 2x > -10 x > -5
What is the comparison symbol of 4 1?
The inequality symbol.
When you have to reverse the inequality sign?
The usual case is when you multiply or divide an inequality by a negative number.
When solving an inequality when do you reverse the inequality sign?
When you divide both sides by a negative value
What happens to the inequality symbol when you subtract a negative number?
The inequality symbol doesn't change direction in this case.Note that that is the same as adding a positive number.Note also that if you MULTIPLY or DIVIDE by a negative number, then you need to change the direction of the inequality symbol.
Do you swap the inequality symbol when its on the right?
No you do not.
What is the math symbol for is at most?
The inequality symbol for less than or equal to: ≤
When graphing a linear inequality the first step is to replace the inequality symbol with a sign?
