equal to 5
4) the product of 10 and a number
5) half of a number is equal to 8
6) the difference of a number and 22 s 44
7) twice a number is equal to 30
8) 7 more than a number is 9
9) 22 less than x is 49
10) z less than 11

the answer is 15% decrease

step-by-step explanation:

where is the questions

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.
