Answer:

Step-by-step explanation:
Given that x and y are proportional and the equation relating them is
y = rx ← r is the constant of proportionality
To find r use any ordered pair from the table
Using x = 9, y = 4.5 , then
4.5 = 9r ( divide both sides by 9 )
= r , that is
r = 
The correct answer is 18 sides.

Answer:
open circle at 7; arrow points left
Step-by-step explanation:
To Solve:
4x - 10 < 18
+ 10 +10
4x < 28
/4 /4
x < 7 *only flip sign when multiply/divide by negative
< means the arrow will point left and that it will be an open circle
