Hello, welcome to Brainly!
If we are to say that no heat was lost, we would have to write this down as a absolute function.
Beaker A lost 18 degrees in the span of 5 minutes (100 - 82) and Beaker B gained 18 degrees in the span of 5 minutes.
This is where the problem gets tricky, because we have no second value for the second line of the function, though I doubt this question is that complicated.
Now, what we do is we subtract 18 degrees from Beaker A, again, since 10 - 5 minutes is 5 minutes. We then add 18 degrees to Beaker B.
Answer:
Beaker A: 64° (82 - 18)
Beaker B: 36° (18 + 18)
