Answer:
Well, there are x amounts of white flower and 6 cups of wheat flower.
So the total flower is x + 6
Given that is the total, the equation you would use is:
y=x+6
The constraints are as follows:
y can only be > 6
And if y=0, x would have to be -6 (which is impossible)
The first one is D because you would divide for amount each day, and the second one is A because that has the correct expression of division.
The independent value that is "n". Hope be usefull
D
A, B, C and E are linear equations ( equations of straight lines )
y = 2x² - 1 is a parabola → not linear → D
