Set up a system of equations in 2 variables.

Answer:

Renee has 9 Chocolate chip cookies and 3 peanut butter cookies.

Step-by-step explanation:

This is a system of equations:

C + p = 12

C = 3P

All you need to do is substitute C for 3P in the first equation.

C + P = 12

3P + P = 12

4P = 12

Divide both sides by 4

4P/4 = 12/4

P = 12/4

P = 3

Now, substitute P for 3 in the first equation.

C + P = 12

C + 3 = 12

Subtract 3 from both sides

C + 3 - 3 = 12 - 3

C = 12 - 3

C = 9

C = 9, P = 3

The graph shows the system y=2x+1 y=2x^2+1 Which ordered pairs are solutions of the system?
zhenek [66]
Hey!


To solve this problem, we would really have to graph both equations.

<em>OPEN THE FIRST IMAGE</em>

The first image I provided was the image of this equation graphed: <span>y=2x+1

<em>OPEN THE SECOND IMAGE</em>

The second image I provided was the image of this equation graphed: </span><span>y=2x^2+1


<em>PLEASE DO NOT LOOK AT THE THIRD IMAGE YET!</em>


The first image has two points. One at ( -0.5, 0 ) and the other at ( 0, 1 ).

The second image has only one point, which is at ( 0, 1 ).

<em>OPEN THE THIRD IMAGE</em>

Now, when both are combined we see that they intersect at two points, which are ( 0, 1 ) and ( 1, 3 ).

So, our answer is...

<em>The ordered pairs that are the solution to the system are</em>  </span><span>( 0,1 ) and ( 1,3 ).

Hope this helped!

How do the graphs of y =1/x and y = 3/x – 4 compare?
Pie
The graphs of y =1/x and y = 3/x – 4 can be compared by saying that c<span>ompared to the graph of y =1/x , the graph of y =3/x – 4 is a vertical stretch by a factor of 3 and a translation of 4 units down. This can be seen clearly when you graph the functions on a x-y coordinate plane.</span>

In an area of the Midwest, records were kept on the relationship between the rainfall (in inches) and the yield of wheat (bushel
dusya [7]

Answer:

The correct answer is 36.2

Step-by-step explanation:

Hello!

Given the data:

Rainfall(inch) x: 10.5, 8.8, 13.4, 12.5, 18.8, 10.3, 7.0, 15.6, 16.0

Yield (bushels per acre) y: 50.5, 46.2, 58.8, 59.0, 82.4, 49.2, 31.9, 76.0, 78.8

The response variable is

Y: Yield of wheat (bushels per acre)

Explanatory variable:

X: Rainfall in a certain period (inch)

I've calculated the equation of regression using a statistics software, the estimated equation is:

^Y= 4.27 + 4.38X

To calculate the value that will take the response variable for a given value of X:

^Y= 4.27 + 4.38*7.3= 36.24 bushels per acre.

I hope it helps!
