**Problem:**

5. Solve the inequality \(|y - 4| < 0.001\). (Report with decimals)

**Solution:**

To solve this inequality involving absolute values, we interpret it as two separate inequalities:

1. \(y - 4 < 0.001\)
2. \(y - 4 > -0.001\)

Solving the first inequality:
\[ y < 4 + 0.001 \]
\[ y < 4.001 \]

Solving the second inequality:
\[ y > 4 - 0.001 \]
\[ y > 3.999 \]

Combining these two inequalities, we find:
\[ 3.999 < y < 4.001 \]

So, the solution in decimal form is:
\[ y \in (3.999, 4.001) \]

This represents the range of values \(y\) can take to satisfy the given inequality.
