Solve by elimination x-5y=35 and 3x-6y=51

x=5 y=-6

(5,-6)

Step-by-step explanation:

Solve by elimination

multiply x-5y=35 by 3

= 3x-15y=105

-

divide 9 on both sides

y= -6

Now solve for x

you must plug in -6 for y in either equations

i plugged in -6 for y in 3x-15y=105

subtract 90 on both sides

Please mark brainliest

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

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.
