This is called diffusion.
Answer:
-6,9 I believe
Step-by-step explanation:
Im pretty sure
Find the least common multiple of 3 and 5:
3: 3,6, 9,12,15,18,21
5: 5, 10, 15, 20
The least common multiple is 15. This means every 15 days they will be the same day.
Add 15 days to May 5:
5 + 15 = 20
The next day would be May 20

Answer:</h2>

<h2>
Step-by-step explanation:</h2>
From the given graph, we can know two points:

Using the slope intercept form of the equation of a line, we get:

Where the slope is
and the y-intercept is 
From mathematics, we know that a system of two linear equations has no solution if and only if the two equations have the same slope, but not the same y-intercept. So, from the options, the second equation is:

And the slope intercept form of this equation is:

So the slope is
and the y-intercept is
, the systems formed by these two equations has no solution.
