Social gaming revenues (via the internet) in billions of dollars from 2010 to 20

Question

Social gaming revenues (via the internet) in billions of dollars from 2010 to 2018 are projected to be modeled by R(x) = 0.86x + 1.2, where x represents years after 2010. interpret the slope in the context of the situation Estimate when (what years) the revenue Is expected to be more than $3 billon. A cold front has moved into a city. The temperature has dropped at rate of 3 degree F per hour between noon and 800 PM. Define your variables. Express the temperature as a function of time given that at 100PM the temperature was 47 degree F. What is the temperature at 8:00pm? Answer in a sentence, At what time is the temperature 30 degree F? Answer in a sentence. Are the following lines parallel, perpendicular, or neither? y = 5x+1 and y = -1/5 x + 6 parallel perpendicular neither y = 2/3 x + 1 and y = 3/2 x + 6 parallel perpendicular neither y = 1/2 x + 1 and y = -2x + 6 parallel perpendicular neither

Explanation / Answer

R(x) = 0.86x + 1.2

a) slope = 0.86 which means 0.86 billion earnings per year from social gaming

b) R(x) > 3

0.86x + 1.2 > 3

x > 2.09

It means that after two years i.e. 2013 the revenue is more than $ 3 billion
