Inequalities, Proportions, and Equation Transformations
This page delves deeper into rozwiązywanie nierówności solvinginequalities and introduces the concept of proportions.
The section begins with solving inequalities using the method of equivalent inequalities, providing a step-by-step example.
Example: Solving the inequality -6x + 11 > -4x + 4, resulting in x < -2
The page then transitions to proportions, explaining the concept and providing examples of how to use proportion properties.
Definition: A proportion is an equation stating that two ratios are equal, typically written as a:b = c:d.
Highlight: The page emphasizes the importance of applying proportion properties in problem-solving.
The final section covers equation transformations, demonstrating how to rearrange formulas to solve for different variables.
Example: Transforming the formula P = a+bh/2 to solve for 'a': a = 2P/h - b
