In the expression 2(10x) + 15y, x represents the number of hours nina works in a week at a clothing store and y represents the number of hours she works in a week as a babysitter. the expression shows how much money nina has earned this month. which statement is true? nina has worked a total of x – y hours so far this month.  nina works 15 hours a week at the clothing store. nina makes 20x dollars at the clothing store each week.  nina makes $10 per hour babysitting each week.

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.
