In 2003, the population of the state of New York was 10.78 million people. In 1990, it was 7.99 million. Using the population growth
formula y = ae

kt, determine the value of k, New York's relative rate of

growth.
a. When will New York's population reach 15 million people?
b. Nevada's population in 1990 was 14.2 million and can be modeled
by y = 14. 2e

0.0079t. Determine when New York’s population will

surpass Nevada's.

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
