Unit Outline

Writing and solving inequalities can be incredibly useful in solving real-world problems by allowing you to model and analyze situations where constraints and conditions are present. For example, inequalities can help manage budgets by representing spending limits and ensuring expenses do not exceed income. Businesses use inequalities to determine pricing strategies, maximize profits, and minimize costs. Inequalities can also aid in time management by representing constraints on how long tasks should take, ensuring efficient allocation of time. In fields like logistics and operations, inequalities help ensure resources such as materials, labor, and machinery are used efficiently without exceeding available limits. Engineers use inequalities to design structures and systems that meet safety and performance standards. In health and nutrition, inequalities can monitor and maintain health by ensuring nutritional intake stays within recommended limits. Environmental planning also benefits from inequalities, helping to manage resources sustainably and comply with regulations. By understanding and applying inequalities, you can make informed decisions, optimize outcomes, and solve complex problems effectively in various aspects of everyday life and professional fields.

​

By the end of this unit, you will have developed a comprehensive understanding of solving inequalities through a process of reasoning, enabling you to articulate the underlying logic behind your solutions. You will gain the ability to create and solve inequalities in one variable, applying these skills to a variety of problem-solving scenarios. You will also learn to represent constraints using inequalities and interpret the resulting solutions to determine their viability. Additionally, you will become proficient in graphically representing and solving inequalities, enhancing your overall problem-solving toolkit.
