Question

given y varies directly as x, and y=9 when x=3. Find y when x=11

Answer 1

it would be 17

Answer 2

y = ax 9 = a3 so a = 3

y = 3x y = (3)(11)

Answer 3

So, y would equal 33.

Answer 4

no.... it wouldn't

O.o

Answer 7

Answer 9

go right ahead, np.

Answer 10

given y varies directly as x and y=4 when x=20. Find x when y=6

Answer 11

y = ax 4 = a(20) a = (1/5)
y = (1/5)x x = 5y x = (5)(6) = 30

Answer 12

y=ax y=(20)(6)

Answer 13

it'S 20 AND 6! URG

Answer 14

So, all I did was basically the same thing, but the only twist here is that I flipped the "x" and "y". See that?

Answer 15

yeah i seen tht

Answer 16

So, with these "varying directly" problems, you can start out the same way in both cases. Nice working with you!
