Question

if y varies inversely with x, and y=-16 when x=-64, what is the constant of variation?

Answer 1

y = kx is the formula

Answer 2

y = kx
-16 = -64x
k = 0.25

Answer 3

* -16 = -64k

Answer 4

So the answer is 64? @greenlegodude57

Answer 5

No, it's 0.25

Answer 6

Ugh I hate math @greenlegodude57 thank you

Answer 7

xD

Answer 8

Not quite...

Inversely means the formula would be

\[\large y = \frac{k}{x}\]

\[\large -16 = \frac{k}{-64}\]
\[\large k = -16 \times -64 = 1024\]

Answer 9

Direct Variation \(\large y = kx\)
Varying Inversely \(\large y = \frac{k}{x}\)

Answer 10

Oh..

Answer 11

My Bad.
