it would be 17
y = ax 9 = a3 so a = 3 y = 3x y = (3)(11)
So, y would equal 33.

no.... it wouldn't
Good luck to you in all of your studies and thx for the recognition! @lvasquev462
O.o
i have one more of these questions
sure :P
go right ahead, np.
given y varies directly as x and y=4 when x=20. Find x when y=6
y = ax 4 = a(20) a = (1/5) y = (1/5)x x = 5y x = (5)(6) = 30
y=ax y=(20)(6)
it'S 20 AND 6! URG
So, all I did was basically the same thing, but the only twist here is that I flipped the "x" and "y". See that?
yeah i seen tht
So, with these "varying directly" problems, you can start out the same way in both cases. Nice working with you!
