Sally has 5 red cards, numbered 1, 2, 3, 4, and 5, and 4 blue cards, numbered 3, 4, 5 and 6.
she wants to line them up so that the colors alternate, and so that the number on each red card is a factor of every number next to it.
how can she do this?

make sure you have version 2.50

try looking in the very back of the book : )

answer: 1+1

step-by-step explanation: 1+1 is at least 2

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.
