Answer:
Step-by-step explanation:
2/3+1/3x=2x
moving all the x to one side
2/3=2x-1/3x
factoring out x
2/3=x(2-1/3)
dividing
(2/3)/(2-1/3)=x
162 cow-days
Since the initial grass and the grass accumulated over 4 days is equal to 144 cow-days, the initial grass is equal to (144 − 36) or 108 cow-days. Now, to find the answer to the question: in 18 days, the grass accumulation is equal to 18 ∗ 9 or 162 cow-days.

Answer:
integers are closed under division
Step-by-step explanation:
Integers are not closed under division.Let us consider two integers i and j.
Then ![\[\frac{i}{j}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7Bi%7D%7Bj%7D%5C%5D)
need not necessarily be an integer. For example, 2 and 3 are integers but ![\[\frac{2}{3}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B2%7D%7B3%7D%5C%5D)
is not an integer. So the first option , namely, integers are closed under division is not true.
On the other hand, the remaining three options given are correct.
The y intercept of 4 means the graph crosses the vertical y axis at 4. More specifically this location is (0,4)
Start at (0,4) and move down 5 units and then move to the right 1 unit. You should arrive at (1,-1). The movement rule of "down 5, over to the right 1" is taken exactly from the slope of -5 = -5/1.
After plotting the two points (0,4) and (1,-1), draw a straight line through them both. Extend this line as far as you can in either direction. The graph is now completed.
<h3>In summary, this line goes through (0,4) and (1,-1)</h3>
Side note: The equation of this line is y = -5x+4. It is in slope intercept form.
