If y varies inversely with x, and y = 2 when x = 8, what is k, the constant of proportionality? a. 16 c. 8 b. 32 d. 24

The constant of proportionality, k = 16

Step-by-step explanation:

The expression "y varies inversely with x" means that y is given by the expression:

and varies inversely because as x increases its value, the values of y decreases.

Now, to find the value of k, the constant of proportionality, we have to put it in the expression:

And resolving for k, we have:

Now, we have to replace the values y=2 and x=8:

k = 8*2

k = 16

step-by-step explanation:

thats the first half

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
