Math Problem Statement
Solve the below compound inequality: x + 5 ≥ 2 and 5x - 7 ≥ 3
Solution
To solve the given compound inequality:
Step 1: Solve each inequality individually.
For :
For :
Step 2: Combine the solutions.
Since it is a compound inequality with "and," we take the intersection of the solutions:
- From , the possible values are .
- From , the possible values are .
The overlap (intersection) of and is:
Final Solution:
Let me know if you have any questions or want further clarifications.
Related Questions:
- How would the solution differ if it were "or" instead of "and" in the compound inequality?
- What are the key differences between solving compound inequalities and absolute value inequalities?
- How would you graph the solution on a number line?
- Can inequalities have solutions that are a range rather than a single value?
- 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!
