Determine whether y varies directly with x. If so find the constant of variation. y = 7/x. Select one: a. No b. Yes, k equals 1/7 c. Yes, k equals 7 d. Yes, k equals -7 Determine whether y varies directly with x. If so find the constant of variation. y = 7x. Select one: a. Yes, k equals -7 b. Yes, k equals 1/7 c. Yes, k equals 7 d. No Determine whether y varies directly with x. If so find the constant of variation. y = x/7. Select one: a. No b. Yes, k equals -7 c. Yes, k equals 1/7 d. Yes, k equals 7

for first question y varies indirectly with x and k equals 7

OpenStudy (anonymous):

Sorry I wasn't at my computer @skylark06

OpenStudy (anonymous):

Y= kx

OpenStudy (anonymous):

direct means y=kx and indirect means y=k/x

OpenStudy (anonymous):

similarly u can do for other problems too )

OpenStudy (anonymous):

So this variation is indirect

OpenStudy (anonymous):

yeah first one is indirect. second one is direct third one is direct again

OpenStudy (anonymous):

wouldn't third one be indirect?

OpenStudy (anonymous):

nopes because the both variables are directly proportional. in third one k=1/7

OpenStudy (anonymous):

Oh

OpenStudy (anonymous):

and the second one. Yes, k equals 7

OpenStudy (anonymous):

yep!!! k=7 :)

OpenStudy (anonymous):

Thanks

OpenStudy (anonymous):

pleasure :) anytime.
