The best way to approach this problem is to look at the graph of the given function. Replace values of x from 1 to 24 to indicate the numbers of hours in a day. As seen on the graph, there is only one point where the port is at high tide. That would be at 1:00 am.
Looking at the graph, it would be safe for the boats to be in the port when the graph levels off at around 10 to 24. That's from 10 am to before 12 midnight. Then, they would have to stay away between 12 midnight to before 10 am.

Answer:
The correct options for the solution values are:
Step-by-step explanation:
Given the expression
Subtract 25 from both sides
Simplify
Add 25 or 5² to both sides
as
so the expression becomes
solve
Subtract 5 from both sides
solve
Subtract 5 from both sides
Therefore, the solution to the equation
Hence, the correct options for the solution values are:
