Tha values of x and y vary directly and one pair of values are given Write an equation that relates x and y Simplify completely x 12 y3 class=

Respuesta :

Answer:

Y=kx

3 = k x 12

÷12

1/4=k

Y=0.25x or y=1/4x

0.25 x 12 =3

Answer:

Step-by-step explanation:

Direct proportion.

So, y = kx

Plugin x = 12  and y=3

3 = k *12

[tex]\dfrac{3}{12}=k\\\\\\\dfrac{1}{4} = k[/tex]

[tex]y=\dfrac{1}{4}x[/tex]
