Provide the missing information. The forget the minus sign definition of the absolute value isuseless for our purposes. If the number on the other side of the inequality sign is negative your equation either has no solution or all real numbers as solutions.

Use the sign of each side of your inequality to decide which of these cases holds. We want the distance between and 5 to be less than or equal to 4. When we take the absolute value of a number.

This will be written as a union. Graphing Absolute Value Inequalities Worksheet. B 4x-7.

Every real number x is a solution because x 0 for any real x meaning that x -3 for all real x. Graphing Absolute Value Inequalities Worksheet. Instead we will mostly use the geometricdefinition of the absolute value.

The absolute value of x x can never be negative so it can never fail to satisfy this inequality. Jabj jajjbj the absolute value of the product of two numbers is the product of the absolute values. That means for x which is 0 we get x x.
