Solve: 1. 12 + 2 ( x - 1 ) = 4x - 15 - 2x 2. 7 ( x + 3 ) - 1 = 5 ( x + 4 ) + 10
3. ( 4x - x ) 6 + 2 = 11 ( x + 3 ) + 10
4. 3/8 ( 2x - 8 ) = 1/4x + 9

step-by-step explanation:

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.
