You can use elimination by adding the two equations to "cancel out" one of the variables. in this example y will cancel out.

2x + y = 3
+
2x - y = 4
________
2x = 6
x = 3 

now that we know our x value, we can plug it into one of the other equations to get our y value.

2(3) + y = 3
6 + y = 3
y = -3

your answer for this system is x=3, y=-3

Anna007 [38]

Answer:

Therefore, the bed turnover rate for March was 4.5416.

Step-by-step explanation:

We know that community hospital a 120 bed facility reported that in March there were 545 discharges. We calculate what was the bed turnover rate for March.

The Direct Variation Formula is y=kx.

We know that y=545 discharges and x=120 bed.

Therefore, we get:

y=k\cdot x\\\\545=k\cdot 120\\\\k=\frac{545}{120}\\\\k=4.5416

Therefore, the bed turnover rate for March was 4.5416.

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
Below is the solution:

<span>distance = 475
</span>time = 9.5 hrs

<span>since distance and time varies directly
</span>
therefore in 9.5 hrs train travels 475 miles => In 1 hr train travels 475 / 9.5 miles = 50 miles
<span>and in 4 hrs train travells 50*4 i.e 200 miles </span>

Crazy boy [7]

Step-by-step explanation:

H(x)=

\frac{f(x)}{g(x)}

If g(x) values =0, h(x) will be undefined.

So f(x)=0, h(x) will be undefined.

Zo find values of f(x) equal 0.

That is when x=2. So the answer to first solution is 2.

h(x) is negative when (-oo, -3) U (2,oo)
