<h3>x = -6, y = 9, z = -3</h3>
Im not entirely sure but, if you're on plato answer D is correct
model 1 has a random pattern and is fit for the data
Answer and Step-by-step explanation: An equation represents proportional relationship when dividing the quantities of the equation results in a quotient that is always the same. For example, in general:
Equation: y = mx
= m
m is a constant value, which means is the same.
A. Equation: 120 - x = L
Equation from alternative A is NOT proportional since the division of the quantities doesn't result in a constant.
B. Equation: 1.08p = t
Dividing total cost per item's price, will always give the sales tax, which is constant. So, this equation IS proportional.

C. Equation: 
This equation is proportional because dividing marbles per how much each sister gets, always gives the number of sisters:

D. Equation: 
This equation is NOT proportional because side length is squared, so it is not constant linearly.
3+2 = 5
80/5 =16
16 x 3 = 48
16 x 2 = 32
Answer= 48:32
I think this is right
