Question

If x varies inversely with y and x = 8 when y = 6, find y when x = 10.

a. y - 5/12
b. y = 4.8
c. y = 40/3
d. y = 7.5

Answer 1

Please note that you have to solve this equation:
\[6 \cdot 8 = 10 \cdot y\]
what is y?

Answer 2

do you know the equation that u have to use for inverse variation ??

Answer 3

\[\huge\rm y = \frac{ k }{ x }\] this is equation that u have to use
now replace x and y by their values
and solve for k

Answer 4

I think it is D but I am not sure

Answer 5

nope

Answer 6

use first x and y values to solve for k
