Beyond the Answer
Let’s solve the inequality step-by-step.
Starting with the inequality:
\[
\left|\frac{w+4}{2}\right| + 3 < 9
\]
First, we simplify by subtracting 3 from both sides:
\[
\left|\frac{w+4}{2}\right| < 6
\]
Now, we can break this absolute value inequality into two cases:
1. \(\frac{w+4}{2} < 6\)
2. \(\frac{w+4}{2} > -6\)
**For the first case:**
\[
\frac{w+4}{2} < 6
\]
Multiply both sides by 2:
\[
w + 4 < 12
\]
Subtract 4 from both sides:
\[
w < 8
\]
**For the second case:**
\[
\frac{w+4}{2} > -6
\]
Multiply both sides by 2:
\[
w + 4 > -12
\]
Subtract 4 from both sides:
\[
w > -16
\]
Now, combining both parts, the solution set is:
\[
-16 < w < 8
\]
So the correct answer is:
A. The solution set is \( \{w \mid -16
