Will mark ! (10 points also! ) if x varies inversely with y and x =6 when y= 10, find y when x=8 a. y=4.8 b. y=7.5 c. y=40/3 d. y=4/15

  (B) 7.5

Step-by-step explanation:

Inversely means: x · y = k

Find k for the given x & y-values.  Then input the new x-value to find y.

x · y = k

6 · 10 = k

  60 = k

x · y = 60

8 · y = 60

       = 7.5

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope
