Acertain shade of pink is created by adding 3 cups of red paint to 7 cups of white paint. what is the constant of proportionality? also could u explain why pls.

Constant of proportionality is the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality.

To make color pink,

for every 3 cups of red , we need 7 cups of white.

Let 'r' be the cups of red required

let 'w' be the cups of white required

so , as per the question

for 3 r we need = 7 w

r = 7/3 w

so, 7/3 is constant of proportionality

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
