WebTry to remember that if you divide by a negative value then the inequality flips. For example, the equation: -3x < 12 becomes x > -4 because you have divided both sides by a negative value. To check if this is correct, replace x with a value that is less than -4 such as -5. Then evaluate the original equation to see if it makes sense. WebAn algebraic inequation can be solved as follows: Step 1: Write the inequality as an equation first. Step 2: For one or more values, solve the given equation. Step 3: …

WebThe reason this happens is the absolute value always creates a positive number. And, a positive number will never = a negative number. So, let's extend that concept to inequalities. 1) An absolute value < a negative: In this situation, we have a positive value < a negative value. That would always be false.

WebGraphing an inequality on a number line, is very similar to graphing a number. For instance, look at the top number line x = 3. We just put a little dot where the '3' is, right?

WebThe graph is shaded above (not below), so y y is greater than the other side of the inequality. The graph has a dashed line (not solid), so we aren't dealing with an "or equal to" inequality. Therefore, we should use the greater than symbol.
