Donte simplified the expression below. 4(1+3) - (8-51) 4+31-8+51 -4+81 what mistake did donte make?

the answer is 8/21

hope this

t

step-by-step explanation:

ever thing time 1 is a multiply by 1 it get  

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)

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.
