Match each combination to the corresponding value. Two real-valued functions, Ax) and gx), are defined as x) = x + 6x +9 and g(x) = x2 - 9. Find the results of combining these functions.
(f+g)(x)
(f-9)(x)
(fx g)(x)
(f=9)(x)
6(x+3)
2x(x + 3)
(+3)
(1-3)
X4 + 6x2 - 54x-81

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90

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.

a is the best answer choice
