In the 'Variations' chapter, we will be learning about direct variation, inverse variation, and combined variation. Direct variation refers to a relationship between two variables where one variable increases or decreases in direct proportion to the other. We will learn how to determine the relation between two variables for a direct variation. Inverse variation, on the other hand, is a relationship where one variable increases while the other decreases, or vice versa. Lastly, combined variation involves both direct and inverse variation in the same equation. We will explore how to solve problems involving combined variation.
• Explain the meaning of direct variation.
• Determine the relation between two variables for a direct variation.
• Determine the relation between three or more variables for a given joint variation
• Solve problems involving direct variation
• Explain the meaning of inverse variation.
• Determine the relation between two variables for an inverse variation.
• Solve problems involving inverse variation.
• Determine the relation between three or more variables for a combined variation
• Solve problems involving combined variation.
