Gamal spent $12.50 at the book store. The difference between the amount he spent at the video game store and the
amount he spent at the book store was $17. The equation d-12.50 - 17 can be used to represent this situation, where
d is the amount Gamal spent at the video game store. Which equation is an equivalent equation that can be used to
find the amount Gamal spent at the video game store?
Od- 17-12.50
Od- 17+12.50
Od-12.50 - -17
d+ 12.50 = 17

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.

answer is 8 r5
