Let's change the signs a bit: M' = aM - BMH H' = XH - MH This is no longer a model for a predator-prey relationship. What might it be modeling instead? There are different versions of this basic system of equations that are used to model different types of relationships in nature. These are called Lotka-Volterra systems.

7. In class, we learned about the predator-prey system of differential equa-
tions. Here's a system using mice M (t) and hawks H(t), with t measured
in days.
M' = aM - BMH
H' = −λH +yMH

Let's change the signs a bit:
M' = aM - BMH
Η' = λΗ – ΥΜΗ
