4 0

Answer:

see below

Step-by-step explanation:

27) y = kx

18 = k(20)

18 = 20k

k = 0.9

28) y = kx

-9 = k(3)

-9 = 3k

k = -3

y = -3x

29a) y = kx

5 = k(1/3)

5 = 1/3k

k = 15

y = 15x

29b) y = 15x

y = 15(-2)

y = -30

In Exercises 5-8, find the perimeter and area of the polygon with the given vertices.

Check the picture below.

as we can see in the picture, the lengths for YZ and ZX are very straight, let's get the side YX

$~~~~~~~~~~~~\textit{distance between 2 points} \\\\ Y(\stackrel{x_1}{0}~,~\stackrel{y_1}{-2})\qquad X(\stackrel{x_2}{2}~,~\stackrel{y_2}{4})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ YX=\sqrt{[2 - 0]^2 + [4 - (-2)]^2}\implies YX=\sqrt{2^2+(4+2)^2} \\\\\\ YX=\sqrt{4+6^2}\implies YX=\sqrt{40} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{\Large Perimeter}}{2~~+~~6~~+~~\sqrt{40}~~\approx~~14.32} ~\hfill \stackrel{\textit{\Large Area}}{\cfrac{1}{2}(2)(6)\implies 6}$
