The solution set for the inequality is all numbers less than or equal to \(\frac{34}{9}\) and all numbers greater than or equal to 2.

Solución

To find the solution set for the inequality, we need to analyze the given intervals: 1. **Interval \( (-\infty, 2] \)**: This includes all numbers less than or equal to 2. 2. **Interval \( \left(-\infty, \frac{34}{9}\right] \)**: This includes all numbers less than or equal to \(\frac{34}{9}\). 3. **Interval \( [2, \infty) \)**: This includes all numbers greater than or equal to 2. 4. **Interval \( \left[\frac{34}{9}, \infty\right) \)**: This includes all numbers greater than or equal to \(\frac{34}{9}\). Next, we need to determine the relationship between these intervals, particularly focusing on the critical points \(2\) and \(\frac{34}{9}\). ### Step 1: Compare the critical points First, we calculate \(\frac{34}{9}\): \[ \frac{34}{9} \approx 3.78 \] ### Step 2: Analyze the intervals - The interval \( (-\infty, 2] \) includes all values up to 2. - The interval \( \left(-\infty, \frac{34}{9}\right] \) includes all values up to approximately 3.78. - The interval \( [2, \infty) \) includes all values starting from 2. - The interval \( \left[\frac{34}{9}, \infty\right) \) includes all values starting from approximately 3.78. ### Step 3: Determine the union of intervals Now, we can combine these intervals based on their overlaps: - The first two intervals \( (-\infty, 2] \) and \( \left(-\infty, \frac{34}{9}\right] \) can be combined into \( (-\infty, \frac{34}{9}] \). - The last two intervals \( [2, \infty) \) and \( \left[\frac{34}{9}, \infty\right) \) can be combined into \( [2, \infty) \). ### Final Solution Set Thus, the overall solution set for the inequality is: \[ (-\infty, \frac{34}{9}] \cup [2, \infty) \] This means the solution set includes all values less than or equal to \(\frac{34}{9}\) and all values greater than or equal to 2.

Let's dive into the fascinating world of inequalities! Inequalities have been used for centuries to help solve various problems, from simple number comparisons to more complex mathematical models. The great mathematician Euclid even touched on similar concepts in his work over 2,300 years ago! Now, onto the real-world application! Inequalities are everywhere around us, from finance (like budgeting or earnings thresholds) to physics (like determining safe limits for forces acting on structures). They allow us to express conditions and constraints in everyday decisions, making them not just a math topic but a practical tool in life!
