What is a one-step inequality?

A one-step inequality is an inequality that can be solved in one step by performing a single operation (such as addition, subtraction, multiplication, or division) on both sides of the inequality to isolate the variable. These inequalities involve only one inequality sign (<, ?, >, or ?) and can represent relationships where one quantity is greater than or less than another.

What is the difference between an inequality and an equation?

An inequality represents a relationship between two expressions that are not necessarily equal, but rather indicate a comparison of values such as greater than, less than, greater than or equal to, or less than or equal to. An equation, on the other hand, represents a relationship between two expressions that are equal to each other. In summary, an inequality shows a relationship of comparison between values, while an equation shows a relationship of equality between values.

How do you solve a one-step inequality with addition or subtraction?

To solve a one-step inequality with addition or subtraction, simply isolate the variable by performing the opposite operation. If you are adding a number, then subtract the same number from both sides of the inequality symbol. If you are subtracting a number, then add the same number to both sides of the inequality symbol. Finally, simplify the inequality to find the solution for the variable.

How do you solve a one-step inequality with multiplication or division?

To solve a one-step inequality with multiplication or division, simply isolate the variable by performing the inverse operation. If you are multiplying the variable by a number, divide both sides of the inequality by that number. If you are dividing the variable by a number, multiply both sides of the inequality by that number. Remember to follow the same rules as solving equations, such as maintaining the inequality sign and being cautious of dividing by zero.

What happens when you multiply or divide both sides of an inequality by a negative number?

When you multiply or divide both sides of an inequality by a negative number, the direction of the inequality sign is reversed. For example, if you multiply both sides of the inequality 2 < 5 by -3, it becomes -6 > -15. This is because multiplying or dividing by a negative number changes the direction of the inequality due to the properties of number operations and maintains the relationship between the numbers involved.

How do you represent the solution to a one-step inequality on a number line?

To represent the solution to a one-step inequality on a number line, you would use an open or closed dot to indicate the boundary value, depending on whether the inequality includes or excludes that value. Then, you would shade the region that satisfies the inequality by extending the shading in the direction of the solution. The final result would show the range of values that make the inequality true, with the boundary point(s) clearly marked.

What does it mean if a value is included or excluded in the solution to a one-step inequality?

If a value is included in the solution to a one-step inequality, it means the value satisfies the inequality and is a valid solution. If a value is excluded from the solution, it means the value does not satisfy the inequality and is not a valid solution.

How can you check if your solution is correct for a one-step inequality?

To check if your solution is correct for a one-step inequality, simply substitute the value you found back into the original inequality and see if it holds true. If the inequality is satisfied when using your solution, then you have found the correct answer. If the inequality does not hold when you substitute your solution, then you may need to revisit and re-evaluate your work to find the correct solution.

What are some common mistakes to avoid when solving one-step inequalities?

Some common mistakes to avoid when solving one-step inequalities include: not properly applying the inverse operation when isolating the variable, forgetting to reverse the inequality sign when multiplying or dividing by a negative number, making errors in basic arithmetic operations, and not simplifying the final solution to its simplest form. It is important to double-check each step of the solution process and be mindful of the rules governing inequalities to avoid these common mistakes.

What real-life situations can be represented by one-step inequalities?

One-step inequalities can represent various real-life situations such as determining minimum or maximum limits in a budget, finding acceptable range of temperatures for a thermostat setting, identifying acceptable speed limits while driving, determining the minimum number of items needed to receive a discount, and setting boundaries for time management.
