Answer: True

If one variable goes down, then the other goes up, and vice versa. Think of it like a see-saw. We'll have x on one side pushing down to make y go up. An example of this would be y = 1/x which graphs out a hyperbola.

wlad13 [49]

Answer:

270 downloads

Step-by-step explanation:

Call x the number of times the standard quality version was downloaded and call y the number of times the high quality version was downloaded.

So, we know that

2.5x + 4.4y = 5427 MB     (1)

We also know that the high-quality version was downloaded four times as often as the standard version.

So

y = 4x        (2)

We substitute equation (2) in equation (1) and solve for x.

2.5x + 4.4 (4x) = 5427\\\\2.5x +17.6x = 5427\\\\20.1x=5427\\

x = 270\ downloads
