Please hurry!! A train carrying 3/4 ton of coal drops off 1/3 ton in Pittsburgh, then drops off 1/6 ton in Buffalo. How much coal is the train carrying after it leaves Buffalo?

1/4 ton

Step-by-step explanation:

1/3 + 1/6 = 3/6 = 1/2

Therefore:

3/4 - 1/2 = 1/4

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
