Math Problem Statement

Solve the below compound inequality: x + 5 ≥ 2 and 5x - 7 ≥ 3

Solution

To solve the given compound inequality:

x+52and5x73x + 5 \geq 2 \quad \text{and} \quad 5x - 7 \geq 3

Step 1: Solve each inequality individually.

For x+52x + 5 \geq 2:

x25x \geq 2 - 5 x3x \geq -3

For 5x735x - 7 \geq 3:

5x3+75x \geq 3 + 7 5x105x \geq 10 x105x \geq \frac{10}{5} x2x \geq 2

Step 2: Combine the solutions.

Since it is a compound inequality with "and," we take the intersection of the solutions:

  • From x3x \geq -3, the possible values are x3x \geq -3.
  • From x2x \geq 2, the possible values are x2x \geq 2.

The overlap (intersection) of x3x \geq -3 and x2x \geq 2 is: x2x \geq 2

Final Solution:

x2x \geq 2

Related Questions:

  1. How would the solution differ if it were "or" instead of "and" in the compound inequality?
  2. What are the key differences between solving compound inequalities and absolute value inequalities?
  3. How would you graph the solution on a number line?
  4. Can inequalities have solutions that are a range rather than a single value?
  5. How can inequalities be used to model real-life constraints or problems?

Tip: Always check the direction of the inequality sign and remember to reverse it if you multiply or divide by a negative number!
