Just remember, its me again - i can do algebra all day.

We do the same thing, we multiply 6 by each thing in the parenthesis which gives us 6b - 6*3 = 6b - 18. Then we get 6b -18 = 6. Then since we have -18 we can move it to the other side and make it positive. So then we get 6b = 6+18 = 24. So now we have 6b = 24. Then we divide both sides by 6 seen as we have 6b. So 24/6 = 4. Therefore b  is 4. Im can solve more questions like these but this is your third in a row and we have explained how to do this. It would make me happy if you tried solving this as your own. The reason this explanation is long is so that you understand what we're doing and you can solve on your own. So please next question you post solve on your own. If you still dont understand then feel free to tell me.

i dont have skype lol

Step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
