1.The population of Austin, Texas, is growing at a rate of 3.9% per year. If the
population in 2010 was approximately 790,000, what is the predicted
population for 2020?
Predicted population for 2020:

2.The population of Boston, Massachusetts, is growing at a rate of 1.8% annually.
The population in 2013 was approximately 636,500. What is the predicted
population for 2025?
Predicted population for 2025:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are

1,8,15,22,29,36,43,50

step-by-step explanation:

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
