Pls now asap will give brainliest the variables y and x have a proportional relationship, and y = 15 when x = 3. what is the value of x when y = 4?

x =

Step-by-step explanation:

given that y and x are proportional then the equation relating them is

y = kx ← k is the constant of proportionality

to find k use the given condition y = 15 when x = 3, hence

k = = = 5

y = 5x ← equation of proportionality

when y = 4, then

5x = 4 ( divide both sides by 5 )

x =

line or a linear equation graph

step-by-step explanation:

1. minimum

2. 6400

3. eight

hope this !
