To solve the compound inequalities given, we will solve each inequality separately.
1. For the first inequality:
\[
4x - 3 > 9
\]
We add 3 to both sides:
\[
4x > 12
\]
Now, divide both sides by 4:
\[
x > 3
\]
2. For the second inequality:
\[
x + 6 > -2
\]
We subtract 6 from both sides:
\[
x > -8
\]
Now, combining both inequalities, we are looking for values of \( x \) that satisfy both:
\[
x > 3 \quad \text{and} \quad x > -8
\]
Since \( x > 3 \) is a stricter condition than \( x > -8 \), the solution to the compound inequalities is simply:
\[
x > 3
\]
Thus, the solution set is:
\[
\{x | x > 3\}
\]
Therefore, the correct response is:
\[
\{x | x > 3\}
\] (left brace x vertical bar x greater than 3 right brace).
