y varies jointly with p and q. the formula would be y=kpq 60=k(4)5 solve for k then Find y when p = 5 and q = 8.

@yazthespaz , you can follow @mark_o. I need a few min, sorry

y= k(5)(8)= 40 so the answer is y = k (40)

  • anonymous
which will equal y = 40

@Brittni0605 okay, its fine
anonymous
  • anonymous
yes correct but did you do how to solve for k earlier
anonymous

.60=k(4)5

60=k(4)5 60=k(20) so 60/20=k k=__? ok good luck now it seems you got now the correct answer... :D
