Which is the approximate solution to the system y = 0.5x + 3.5 and y = −x + shown on the graph?

I'm assuming there is a graph with both functions plotted. The solution would be the point at which these two functions intersect. That coordinates of x and y for that point will yield the solutions for x and y that solve the system of equations.

What is one ninth plus two thirds simplified

GREYUIT [131]

7/9. 1/9 plus 2/3. You have to get the lest common denominator, so change 3 to 9 by multiplying it by three. Remember, you have to do the same thing you do to the denominator to the numerator. So, 2/3 would be 6/9. 6/9 plus 1/9 is easy, basic facts. 1 and 6 is 7, and you put the nine under. You get 7/9

1.) What is the best approximation of the solution to the system to the nearest integer values?

melisa1 [442]

<u>Part 1)</u> we have

$5x+2y=16$ ------> equation A

$x+3y=12$

$x=12-3y$ ------> equation B

Substitute the equation B in equation A

$5[12-3y]+2y=16$

$60-15y+2y=16$

$13y=44$

$y=44/13=3.38$

Find the value of x

$x=12-3(44/13)=1.85$

the best approximation is the point $(2.3)$

therefore

<u>the answer Part 1) is the option C</u>

$(2.3)$

<u>Part 2) </u>we have

$y=-x-2$ ------> equation A

$y=3x+2$ ------> equation B

equate equation A and equation B

$-x-2=3x+2$

$4x=-4$

$x=-1$

Find the value of y

$y=-(-1)-2=-1$

the solution is the point $(-1,-1)$

therefore

<u>the answer Part 2) is </u>

$(-1,-1)$

the insurance company pays the forecast of 3900 prescriptions claims out of 4500 prescription claims submitted what is the rate

nadya68 [22]

Answer:

x=0.87 or 86.67%

13 prescription claims out of 15 are paid

Step-by-step explanation:

First we organize the data:

prescription claims submitted: 4500

Prescriptions: 3900

The rate of claims paid is calculated using the following formula:

$x =\frac{Paid}{Total}$

We know that:

Paid = 3900

Total = 4500

So

$x =\frac{3900}{4500}$

$x =\frac{39}{45}$

$x =\frac{13}{15}$

x=0.87
