To solve the inequality \( 4(u - 2) < 16 \), we start by distributing and isolating \( u \):
-
Distribute the 4: \[ 4u - 8 < 16 \]
-
Add 8 to both sides: \[ 4u < 16 + 8 \] \[ 4u < 24 \]
-
Divide by 4: \[ u < 6 \]
So the solution to the inequality is \( u < 6 \).
Graphing the solution:
- We will plot the endpoint at \( u = 6 \).
- Since \( u < 6 \) does not include 6 (it's an open interval), we will use an open circle at 6.
- The solution extends to the left of 6, so we will have a ray that continues to the left without an endpoint.
Graph:
- Endpoint at \( 6 \): open circle (since 6 is not included)
- Middle segment: everything to the left of 6, which is represented as: \[ \text{---} \text{(open circle at 6)} \text{---} \] (There are no changes needed in this part of the line, as we're simply highlighting all values less than 6.)
So overall, the graph would look like this:

Here the parentheses indicate that 6 is not included in the solution.
