Which graph represents 2x-5y<15?

Step-by-step explanation:

First view 2x-5y<15 as the equation 2x - 5y = 15.  Find the x- and y-intercepts and plot them:  

x-intercept:  let y = 0 and find x:  x = 15/2.  Plot (0, 15/2).

y-intercept:  Let x = 0 and find y:  y = -3.  Plot (0, -3).

Draw a dashed line through these two points.  Shade the area BELOW this line.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

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.
