Question 5 1 pts
Time Warner Cable charges $30 per hour and a trip fee of $55 for each service call.
If you pay $265, for how many hours was the technician at your house

7 hours

Step-by-step explanation:

you would have to set up this probelm as an equation. Your equation should be 30h+55=265. The next step would be to subtract both sides of the equation by 55 to get 30h=210. the last step would be to divide both sides of the equation by 3 to get a total of 7 hours.

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.
