Math Problem Statement
Solution
Let's solve the compound inequality given in the image:
Step 1: Solve the first part of the inequality.
Subtract 3 from both sides: Divide by 4: This can also be written as:
Step 2: Solve the second part of the inequality.
Subtract 3 from both sides: Divide by 4:
Step 3: Combine the two inequalities.
We now have: This is written as:
Conclusion:
The solution corresponds to the inequality where is greater than and less than or equal to .
The correct answer is option A: and .
