If Angela were to paint her living room alone, it would take 3 hours. Her sister Naomi could do the job in 5 hours. How many hours would it take them working together? Express your answer as a fraction reduced to lowest terms, if needed.

we don't have enough info to solve this

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.
