Pls help
y = 2x + 2
4x - y = -6

x = - 2, y = - 2

Step-by-step explanation:

Given the 2 equations

y = 2x + 2 → (1)

4x - y = - 6 → (2)

Substitute y = 2x + 2 into (2)

4x - (2x + 2) = - 6 ← distribute and simplify left side

4x - 2x - 2 = - 6

2x - 2 = - 6 ( add 2 to both sides )

2x = - 4 ( divide both sides by 2 )

x = - 2

Substitute x = - 2 into (1) and evaluate for y

y = 2(- 2) + 2 = - 4 + 2 = - 2

solution is x = - 2, y = - 2

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier

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.
