A proportional relationship is described by the equation
... y = k·x
The point (x, y) = (0, 0) is <em>always</em> a solution to this equation.
_____
In short, if the relationship is proportional, its graph will go through the origin. If the graph does not go through the origin, the relationship is not proportional.
___
Note that this is true if the domain includes the origin. You can have y = kx <em>for x > 10 </em>and the graph will <em>not</em> go through the origin because the function is <em>not defined</em> there.
Answer:
11/15 OR 0.73
Step-by-step explanation:
2/5 ---> 6/15
1/3 ---> 5/15
6/15 + 5/15 = 11/15
OR
2/5 ---> 0.4
1/3 ---> 0.33
0.4 + 0.33 = 0.73
Answer:
Y= 40
Step-by-step explanation:
I know the y equals 40 because I used

But for z and x I got stuck, so I hope I helped you a little to move forward with this problem.
