Solve the equation. |k+ 9| = 4 A. {-13,-5)
B. {-5,5)
c. {-5, 13)
D. {all real numbers greater than or equal to -13 and less than or equal to -5}

A.    {-13, -5}.

Step-by-step explanation:

|k + 9| = 4

k + 9 = 4  so k = -5.

k + 9 = -4 so k = -13.

maybe i can

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.
