To solve the inequality \( 12x - 4 < 56 \), we first isolate \( x \).
-
Add 4 to both sides:
\[ 12x < 60 \]
-
Divide both sides by 12:
\[ x < 5 \]
The solution \( x < 5 \) means we need to represent all numbers less than 5 on a number line.
- A closed point at 5 means that 5 is included in the solution; therefore, it does not represent \( x < 5\).
- An open point at 5 indicates that 5 is not included in the solution, which correctly represents \( x < 5\).
Among the provided number lines:
- Graph #1 has a closed point at 5, so it represents \( x \leq 5 \).
- Graph #2 has an open point at 5, showing \( x < 5 \).
- Graph #3 has a closed point between 4 and 5, indicating it includes that point.
- Graph #4 has an open point between 4 and 5, indicating it does not include that point.
Since we are looking for \( x < 5 \), the appropriate graph is:
Graph #2.
