Answer:
y=0x+-6
Step-by-step explanation:
y=mx+b

Above, I changed the fraction form of x and y into exponential form so it is easier to see the differentiation. Now, we can differentiate:

Now that we have dy/dx, we can plug in the x, which is 4, and the y, which is 4/19. We know these values of x and y because your question stated y(4) = 4/19.
Just do 11x18x20x14 and u should get it
You could expect to land on red 120 times because 300*.4=120
