describe how the value of z changes as the values of x and y changes when z=xy
if x is doubled, z doubles
if y is doubled, z doubles
The change in z seems to be the product of the relative changes in x and y.

When the value of z is defined as z = xy, we can observe how the value of z changes as the values of x and y change.
To understand the relationship between z, x, and y, we can use a simple example. Let's say we start with x = 2 and y = 3. Plugging these values into the equation z = xy, we find that z = 2 * 3 = 6.
Now, if we change the values of x and y, say x = 4 and y = 2, we can calculate z again using the same equation: z = 4 * 2 = 8.
From these examples, we can see that as the values of x and y change, the value of z also changes accordingly.
Generally, when we have z = xy for any values of x and y, the value of z will depend on the product of x and y. If x and y are both positive, increasing either x or y will result in an increase in z. Similarly, if x or y is negative, then the sign of z will be negative.
It is important to note that the specific relationship between x, y, and z will always follow the formula z = xy, as long as we are considering only the direct product of x and y. However, if there are other mathematical operations or equations involved, the relationship between x, y, and z may change accordingly.
