Math Problem Statement

For which range of values are the following two inequalities satisfied? 2x + 3 >= 5, x^2 < 9.

Solution

The problem in the image asks for the range of values for which the following two inequalities are satisfied:

  1. 2x+352x + 3 \geq 5
  2. x2<9x^2 < 9

Step 1: Solve 2x+352x + 3 \geq 5

2x+352x + 3 \geq 5 Subtract 3 from both sides:

2x22x \geq 2 Divide by 2:

x1x \geq 1

Step 2: Solve x2<9x^2 < 9

x2<9x^2 < 9 Take the square root of both sides:

3<x<3-3 < x < 3

Step 3: Find the intersection of the two inequalities

The solution for 2x+352x + 3 \geq 5 is x1x \geq 1, and the solution for x2<9x^2 < 9 is 3<x<3-3 < x < 3. To satisfy both inequalities, we need the range where both conditions hold true.

From 3<x<3-3 < x < 3 and x1x \geq 1, the intersection is:

1x<31 \leq x < 3

Final Answer:

The values of xx that satisfy both inequalities are in the range: 1x<31 \leq x < 3

Here are 5 related questions for deeper understanding:

  1. How would the solution change if the first inequality were 2x+3>52x + 3 > 5 instead?
  2. What would happen if the second inequality were x29x^2 \leq 9 instead of x2<9x^2 < 9?
  3. Can you explain how to find the intersection of two inequalities graphically?
  4. How do you solve quadratic inequalities like x29x^2 \geq 9?
  5. How would the solution be affected if one of the inequalities was non-linear (e.g., x3<27x^3 < 27)?

Tip: When solving inequalities involving quadratic expressions, it's helpful to remember that the solutions usually fall between or outside the roots of the related equation.
