A population of amoebas in a petri dish will triple in size every hour. At the start of an experiment the population is 800. The function y=800-3*, where x is the number of hours, models the population growth. How many amoebas are in the petri dish after 9 hours?

Which is the completely factored from of xy^3-x^3y

Find the equation using the point (4,8)

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
