2. Olivia translates rectangle WXYZ vertically up 1 unit and horizontally to the right 4 units to produce the
Image W'X'Y'Z'. Thom translates the rectangle vertically up 6 units and horizontally to the right 5 units
to produce the image W X Y Z
a. Would you prefer to use Olivia's translation or Thom's translation to determine the perimeter
and the area of the rectangle? Explain your reasoning.
b. Calculate the perimeter and the area of the rectangle. Show your work.

if you was gonna solve for a, a is a   < -12

investment b is an ordinary annuity with $3,909.64 in the account after one year.

step-by-step explanation:

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.
