To solve the compound inequality \(-1 < x + 1 \leq 6\), we need to break it down into two separate inequalities and solve each one.
1. Solve the first part: \(-1 < x + 1\)
Subtract 1 from both sides:
\[
-1 - 1 < x + 1 - 1
\]
\[
-2 < x
\]
2. Solve the second part: \(x + 1 \leq 6\)
Subtract 1 from both sides:
\[
x + 1 - 1 \leq 6 - 1
\]
\[
x \leq 5
\]
Now combine both results:
\[
-2 < x \leq 5
\]
So, the solution to the compound inequality \(-1 < x + 1 \leq 6\) is \(-2 < x \leq 5\).
The correct response is:
D \(-2 < x \leq 5\)

Let's re-evaluate the compound inequality \(-1 < x + 1 \leq 6\) step-by-step:
1. Split the compound inequality into two parts and solve each part separately.
\[ -1 < x + 1 \]
Subtract 1 from both sides:
\[ -1 - 1 < x + 1 - 1 \]
\[ -2 < x \]
So, the first part of the inequality simplifies to:
\[ x > -2 \]
2. Solve the second part:
\[ x + 1 \leq 6 \]
Subtract 1 from both sides:
\[ x + 1 - 1 \leq 6 - 1 \]
\[ x \leq 5 \]
Now, combine both parts:
\[ -2 < x \leq 5 \]
This simplifies to:
\[ -2 < x \leq 5 \]
Therefore, the correct answer is indeed:
D. \(-2 < x \leq 5\)
