The answer is B for every change in x by 2, y changes by 4
EXPLANATION:
In the chart, each time they add 2 in the x (-4 +2 is -2, -2 + 2 is 0 and so on) in the y pile they add 4
Answer:
The answer is b = ax- c/x

Step-by-step explanation:
Each tube can be included in the mix, or not. There are 2^9 = 512 possible subsets of a set of 9 objects, including the complete set and the empty set. The empty set will not make a color, so there are ...
2^9 - 1 = 511 distinct color groupings that can be made
__
The assumption in the above answer is that no tube color can be made by any combination of other tube colors.* We also assume that the choice of tubes is what makes a "color grouping", and that the colors within that grouping made by using different ratios of paint quantities are not counted separately.
