james wants to compete in the international speed texting competition next year where
participants compete on text speed and accuracy. james's current text speed is 2
characters per second, james has found that his texting speed increases at a rate of 1/2 a
character per second for each month that he practices.
1. a. what is james's new texting speed if he practices for only 1 month?
b. what is james's new texting speed if he practices for 2 months?
c. what is his new texting speed if he practices for 3 months?
d. write an algebraic equation that gives james's texting speed s for m months of
practice.

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
