The option that best describes the graphed function is: D. inverse variation; k = 4
<h3>What is an Inverse Variation?</h3>
Given two variables x and y has an inverse variation, the equation that models the relationship of the inverse variation is: y = k/x, where k = xy.
This means that as x increases, y decreases. This is the same for the graph given. So, it is an inverse variation.
When x = 2, y = 2. Therefore:
k = (2)(2)
k = 4

Do they give you any other information?
Remember to follow PEMDAS and the "left-to-right" rule
39 x 2 = 78
67 - 78 = -11
-11 + 26 + 78
Combine
(-11 + 26) + 78
15 + 78
93 is your answer
hope this helps
x = # of ham sandwiches
14-x = # of turkey sandwiches ( as Lexi made 14 sandwiches)
as the question said that the number of ha sandwiches are 4 less than twice number of turkey sandwiches,
x = 2 * (14-x) - 4 = 24 - 2x
3x=24
x = 8
the number of ham sandwiches is 8, and the number of turkey sandwiches is 14-8=6
