2x + y - (x + y) = 3z - 6z
--------------------------------------------------------
<span>x = -3z </span>
------------------------------------------
<span>(-3z, 9z) </span>
----------------------------------
<span>(x,y,z) = (-3z, 9z, z)
</span>--------------------------
<span>x = -3z, y = 9z
---------------------
There for the answer is </span><span>(-3z, 9z) </span>
Im not exactly sure but i think its about 12 inches
For linear, the y-differences are equal. An example is the total cost of buying a single type of item.
Quadratic - the 2nd differences are equal,. Example: path of a kicked ball
Cubic - the 3rd differences are equal. Example: modeling the shapes of vases or curved designs
Exponential - the y-ratios are equal. Example: growth of bacteria
