What is a two-step inequality?

A two-step inequality is a mathematical statement formed by combining two inequalities with two different operations, usually involving both addition/subtraction and multiplication/division. Solving a two-step inequality typically requires performing these operations in sequence to determine the possible range of values that satisfy the inequality statement.

How do you solve a two-step inequality?

To solve a two-step inequality, first isolate the variable term by undoing any addition or subtraction operations. Then, undo any multiplication or division operations on the variable to solve for its value. Remember to reverse the inequality sign if you multiply or divide by a negative number. Finally, write your solution as the inequality statement with the variable on one side and the value on the other side and simplify if needed.

What is the purpose of solving two-step inequalities?

The purpose of solving two-step inequalities is to find the range of values for a variable that satisfy the inequality. By breaking down the inequality into smaller steps and solving for the variable, we can determine the values that make the inequality true. This helps in identifying the possible solutions or conditions that need to be met to make the inequality valid, which is crucial in various mathematical and real-world scenarios.

What are the common symbols used in two-step inequalities?

The common symbols used in two-step inequalities include less than (<), greater than (>), less than or equal to (?), and greater than or equal to (?). These symbols are used to compare two values and represent the relationship between them in a mathematical statement.

How can you represent a two-step inequality on a number line?

To represent a two-step inequality on a number line, first plot the points for each boundary of the inequality on the number line. Use an open circle for "<" or ">" and a closed circle for "<=" or ">=". Then, draw an arrow between the points to show the range of values that satisfy the inequality. If the inequality involves addition or subtraction, use the appropriate operation to determine the direction of the arrow. If the inequality involves multiplication or division by a negative number, flip the direction of the arrow.

What are the steps involved in solving two-step inequalities?

To solve a two-step inequality, start by isolating the variable term by undoing the operations in reverse order. First, use the inverse operation of addition or subtraction to get rid of the constant term. Then, use the inverse operation of multiplication or division to isolate the variable. Remember to flip the inequality sign if you multiply or divide by a negative number. Solve for the variable to find the solution set. Be sure to express the solution set using interval notation if required.

What is the difference between solving an inequality and solving an equation?

The main difference between solving an inequality and solving an equation is that when solving an inequality, the solution is a set of values that satisfy the inequality, while when solving an equation, the solution is a specific value or set of values that make the equation true. Inequalities involve comparing two values or expressions using inequality symbols (<, >, ?, ?), while equations involve setting two expressions equal to each other and finding the value(s) that make them equal.

How can you check your solution to a two-step inequality?

To check a solution to a two-step inequality, you can substitute the value you found back into the original inequality and see if it satisfies the inequality. If the inequality is true when you substitute the value, then your solution is correct. If the inequality is false, then your solution is incorrect.

Are there any special cases or exceptions to solving two-step inequalities?

Yes, there is a special case when solving two-step inequalities involving multiplication or division by a negative number. In this case, you need to flip the inequality symbol when multiplying or dividing both sides by a negative number to maintain the correct direction of the inequality. This rule is crucial to getting the correct solution when dealing with inequalities in these cases. Other than that, the general process for solving two-step inequalities remains the same by isolating the variable using inverse operations to find the solution.

Can you give an example of a real-life situation that can be represented with a two-step inequality?

Sure! Let's say you have a budget of $500 for grocery shopping and you want to buy items on sale. An example of a two-step inequality in this situation could be: 2x + 5y ? 500, where x represents the cost of one discounted item and y represents the number of discounted items you want to buy. This inequality represents that the total cost of discounted items (2x) plus the total cost of other items (5y) should not exceed $500 to stay within budget.
