This happened in 1992 - it was the year when the number of Internet host servers reached and broke 1,000,000. The development of the Internet was a slow process, but once it began back in the day, it never stopped advancing and thus we have what we have today.

Given the system of linear equations. Choose all of the options that could be used to solve the system using addition

myrzilka [38]

<h2>Hello!</h2>

The answer is:

The only operations that could be used to solve the system using addition are the first and the third operation.

To solve the problem, we need to check and discard each of the given option to see if the operations works to solve the system using addition, so, trying the given options.

The system of equation is:

$x+y=7\\12x+y=5$

We can see that the only way to solve the system using addition, is multiplying the first or the second equation by -1, so, we can eliminate the variable "y", let's prove that:

- First operation: Multiplying<u> the first equation</u> by -1 and add the equations together,

$x+y=7\\12x+y=5$

$x*(-1)+y*(-1)=7*(-1)\\12x+y=5$

$-x+-y=-7\\12x+y=5$

Adding the equations, we have:

$12x-x+y-y=5-7$

$11x+=5-7$

$11x+=-2$

$x=-\frac{2}{11}$

We can see that we can solve the problem using the first operation the operation.

- Third operation: Multiplying <u>the second equation</u> by -1 and add the equations together,

$x+y=7\\12x+y=5$

$x+y=7\\12x*(-1)+y*(-1)=5*(-1)$

$x+y=7\\-12x+-y=-5$

Adding the equations we have:

$-12x+x+y-y=-5+7$

$-11x=2$

$x=-\frac{2}{11}$

We can see that we can solve the problem using the third operation.

Also, we can see that in both equations the variable "y" has the same coefficient, the only operations that could work to solve the system using addition are the first and the third operation.

Have a nice day!

The correct answer is A. Brief in-text citations connected to a works cited page

Explanation:

MLA stands for Manual and Guide to Scholarly Publishing and consist on a manual with guidelines for edition and publishing of documents with an academic style, according to this manual when using other sources whether this occurs as direct citations or paraphrasing, information about the author should be provided, in the case of in-text citations the last name of the author, date of publication, and in some cases page is included before or after being cited in a brief citation, however, all the information related to the source should be included at the end of the document in a reference list, which is a list of all the works cited or used during the text, in this list wider information of the source is provided such as the title of the source, where was it publish, among other.

Dear Sawera:

Hope you are also good there. I just wanted to discuss my experience of school with you. In this school, I am enjoying everything. My school began at 8:00 A.M. by morning assembly and some exercises. After that, we have a regular schedule of four periods and then lunch which is followed by the next four periods. In my school, we have Saturday off and we can go outside on Saturday from our school hostel. Our teachers do not scold or beat us if we by chance anyone forgets to complete the homework. Our teacher employes fun activities and virtual methods to teach us. I feel lucky that I got admission in this school. I would like to invite you to this school for your further studies.
Yours lovingly
