Combine Variation
Combined variation describes a situation where a variable depends on two (or more) other variables, and varies directly with some of them and varies inversely with others (when the rest of the variables are held constant).
What is an example of combined variation?
Combined Variation: When you combine either joint and inverse or direct and inverse variation in one problem. Example: y varies directly as x and inversely as the square of z, and when x = 32, y = 6 and z = 4. Find x when y = 10 and z = 3.
