[tex] \large \mathbb{Y=36}[/tex]4. If y=12 when x=4, find y when x=12.

[tex] \large \mathbb{14}[/tex]5. If y=-18 when x= 9, find y when x=7.

[tex] \large \mathbb{K=-3/-4}[/tex]6.. If y=-3 when x=-4, find x when y=2.

SOLUTION

4. Direct variation:

y = kx

12 = k4

k4/4 = 12/4

k = 3

If x = 12:

y = k (12)

y = 3 (12)

y = 36 ⇒ ANSWER

5.-14 is the correct answer.Because -18/9 = -2 so 7 x -2 = -14

6. y=-3 y=2

x=-4 x=

-3=k(-4)

-4=-4

k=-3/-4
