Answer:
1. 4
2. y = 4x
Step-by-step explanation:
1.
Divide any y value by its corresponding x value to find the constant of proportionality.
8/2 = 4
Constant of proportionality: 4
2.
Equation of proportional relation:
y = kx, where k is the constant of proportionality.
y = 4x
Answer:
14.13
Step-by-step explanation:
use the radius, 3 squared
so 3 x 3 = 9
9 x 3.14 = 28.26
28.26 / 2 ( because it is a semicircle) = 14.13
Answer:
x=20. y=15
Step-by-step explanation:
in similar triangles the sides are all in proportion. this means:


so:

x=5×4
x=20
and...

y=3×5
y=15
Down 5, right 2
If it's within the parentheses with the x, then it moves left/right. left if +, right if -
If it's outside the parentheses, you go up and down. up if +, down if -
Answer:
cut up the shape
Step-by-step explanation:
if you are looking for area make the 18 yard a triangle so then you have a rectangle and add them together. try this for practice so you can do it on your own next time:)
