Answer:

I believe it might be C. -3

NikAS [45]2 years ago
7 0

Answer:

The answer is C. -3

Step-by-step explanation:

You could go about solving this mathematically or graphically. I'll explain both ways.

Mathematically: Plug the points into this equation

y(2) - y(1) / x(2) - x(1)

If you do this, it will be -2- 4 / 1 - -1, which equals -6/2. You can simplify this to -3 and there you go.

Graphically: Start on the point (-1,4) and count on the graph until you get to (1,-2) That will be down six units and right two units. This can be written as -6/2, which of course, can be simplified to -3.

I hope this helps.

Four individuals pool money together to start a new business and agree to split the profits equally. N invests $6,000, X invests
shepuryov [24]

Answer:

15,000$

Step-by-step explanation:

According to the information given, profits are divided equally into 4 parts

Since the total profit for the first month is 100,000$ each party will receive a sum of 25,000$. This means that Y also receives the same amount

Now if the profits were divided in proportion to the investments made we first find the proportion on investment made by Y.

The total investment made is 6000$ + 2000$ + 8000$ + 4000$ = 20,000$. Out of this, the amount invested by Y is 8000$

finding the proportional profit of Y

\frac{8000}{20000} (100000)

=40,000$

So Y receives 40,000 - 25,000 = 15,000 less
