Me out! combine like terms to solve. check to justify your answer. u + 6 + 5 is less than or equal to -4

u + 6 + 5 ≤ -4

u + 11 ≤ -4

Subtract 11 from both sides.

u ≤ -15

We can replace the value of u with -15, and the inequality should be the same on both sides.

-15 + 6 + 5 ≤ -4

-4 ≤ -4

The inequality is true, and so our solution is correct.

i agree because i see the other persons thinking is clear

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.
