To find the solution set for the inequalities \(4x - 3 > 9\) and \(x + 6 > -2\), we will solve each inequality separately.
1. **Solve the first inequality**:
\(4x - 3 > 9\)
Add 3 to both sides:
\(4x > 12\)
Divide by 4:
\(x > 3\)
2. **Solve the second inequality**:
\(x + 6 > -2\)
Subtract 6 from both sides:
\(x > -8\)
Now we have the two inequalities:
- \(x > 3\)
- \(x > -8\)
The more restrictive condition is \(x > 3\) since any number greater than 3 is also greater than -8. Thus, the solution set is:
\[
\{x | x > 3\}
\]
Therefore, the correct response is:
**A) {x | x > 3}**
1. **Solve the first inequality**:
\(4x - 3 > 9\)
Add 3 to both sides:
\(4x > 12\)
Divide by 4:
\(x > 3\)
2. **Solve the second inequality**:
\(x + 6 > -2\)
Subtract 6 from both sides:
\(x > -8\)
Now we have the two inequalities:
- \(x > 3\)
- \(x > -8\)
The more restrictive condition is \(x > 3\) since any number greater than 3 is also greater than -8. Thus, the solution set is:
\[
\{x | x > 3\}
\]
Therefore, the correct response is:
**A) {x | x > 3}**
