What is an inequality?

An inequality is a mathematical expression that demonstrates a relationship between two values or expressions using symbols such as < (less than), > (greater than), ? (less than or equal to), ? (greater than or equal to), or ? (not equal to). It signifies that one quantity is not necessarily equal to another, establishing a comparison of their values or sizes.

How do you solve a one-variable linear inequality?

To solve a one-variable linear inequality, you need to isolate the variable on one side of the inequality sign. Treat the inequality sign (<, >, ?, ?) just like an equal sign when solving the equation. Perform operations on both sides of the inequality to isolate the variable, remembering to reverse the inequality sign if you multiply or divide by a negative number. Graph the solution on a number line to represent all possible values that satisfy the inequality, noting whether the solution includes or excludes certain values.

How do you graph a one-variable linear inequality on a number line?

To graph a one-variable linear inequality on a number line, first identify the variable and its coefficient in the inequality. Then, determine if the inequality is greater than (>), less than (<), greater than or equal to (?), or less than or equal to (?) a certain value. If the inequality is greater or less than a value, plot an open circle on that value if it's not included in the solution and a closed circle if it is included. Finally, shade the region on the number line that corresponds to the solutions of the inequality based on its direction (above the line for greater than, below the line for less than).

What is the solution set of an inequality?

The solution set of an inequality is the set of all real numbers that satisfy the given inequality when substituted into the equation. It represents all the possible values that make the inequality true. The solution set can be a finite or infinite set of numbers depending on the inequality.

How do you combine inequalities using logical operators (and, or)?

To combine inequalities using logical operators, you can use the "and" operator (represented by ?) to find the intersection of the solutions of two or more inequalities, and the "or" operator (represented by ?) to find the union of the solutions. For example, if you have two inequalities, A and B, combining them with the "and" operator would involve finding the solutions that satisfy both A and B, while combining them with the "or" operator would involve finding the solutions that satisfy either A or B. Remember to carefully consider the conditions of each inequality and how they interact when combining them using logical operators.

How do you solve an absolute value inequality?

To solve an absolute value inequality, first isolate the absolute value on one side of the inequality. Next, break the inequality into two separate inequalities: one for when the expression inside the absolute value is greater than or equal to zero, and another for when it is less than zero. Solve each inequality separately and then combine the solutions to find the final solution set.

What is a quadratic inequality and how do you solve it?

A quadratic inequality is an inequality that contains a quadratic expression with terms involving a variable raised to the power of 2. To solve a quadratic inequality, first, move all terms to one side of the inequality to set it equal to zero. Next, find the critical points by setting the quadratic expression equal to zero and solving for the variable. These critical points will divide the number line into intervals. Choose a test point from each interval and plug it into the original inequality to determine the solution set. Finally, express the solution set using interval notation to represent the ranges of values that satisfy the quadratic inequality.

How do you solve a system of inequalities?

To solve a system of inequalities, graph each inequality to determine the feasible region where they overlap. The overlapping region represents the solutions that satisfy all of the inequalities simultaneously. The solution may be a set of points or a region on the graph. Additionally, you can use algebraic methods, such as substitution or elimination, to find the solution set by solving the inequalities simultaneously.

How do you solve a word problem involving inequalities?

To solve a word problem involving inequalities, first identify the key information and translate it into mathematical expressions using inequality symbols. Then, solve the inequality by performing the necessary operations and steps to isolate the variable. Finally, interpret the solution in the context of the word problem to determine the range of values that satisfy the inequality. Double-check your work to ensure accuracy and consider relevant constraints or conditions given in the problem.

Are there any rules or restrictions when solving inequalities?

Yes, when solving inequalities, you must follow the same rules as when solving equations, such as performing the same operation on both sides of the inequality to maintain its balance. However, there is an additional rule when multiplying or dividing by a negative number - you must reverse the inequality sign to maintain the correct order of the values. Additionally, be cautious when dealing with inequalities involving absolute values, as they may have multiple solutions depending on the sign of the expressions inside the absolute value brackets.
