The model represents an equation what is the value of x

-4x+8=2x-4

Step-by-step explanation:

1.) first you must add in all the triangles in both sides

(on the left there was 4 of -x and on the right there was 2 of x)

leaving it to:

(-4x)+__=(2x)+__

2.) add in all the circles from both sides

(on the left side, there was 8 positive one circles and on the right, there was 4 of negative 1 circles)

leaving the equation being:

-4x+(8)=2x+(-4)

2.) Simplify the equation

-4x+8=2x-4

2/3

Step-by-step explanation:

the constant of proportionality is written as k = y/x, where k is the constant of proportionality and y is the y value and x is the x value

for the given point, y is 2 and x is 3

plug this into your equation: k = 2/3
