Hey!
------------------------------------------------
-x = -1
This statement shows that y equals -1. Since it doesn't show a table or word problem then we already know that the constant of proportionality is -1. Or if you just have the expression just divide the number by 1. -x/1 = -1!
------------------------------------------------
Thus, -1 is the constant of proportionality!

Hope This Helped! Good Luck!
For this case we have:
way 1:
Common factor 3 in the expression:
Way 2:
Write the number 12 as the sum of 4 times 3:

Then, for associative property:
Answer:
69.1²feet
Step-by-step explanation:
area = pi x r²
11x2= 22
22x 3.14 = 69.08
69.1
Answer:
f(3) = -11
Step-by-step explanation:
f(3) means you sub the value that is inside into x
f(3) = -3(3) - 2
= -9 - 2
= -11
