Your life matters. Even if you are failing just take it one step at a time. For a day maybe just try to get caught up in your classes. If you did your best that's what matters. If you really try your best you will succeed in your life. Don't give up now. You're only halfway through the year. Make a change for the better. If you need help ask for it. Hope this helps<3

D). Furthermore, [I believe] the research to be accurate.

Explanation:

Brackets are characterized as the punctuation marks that are used in a sentence to provide additional or supplementary information to the readers for providing better clarity and understanding of the situation that is being described. Among the given options, the last option correctly employs the square brackets as it encloses words ('I believe') in the brackets that were not originally added by the author and provided with the aim of offering clarity to the situation. The first sentence is incorrect as 'sic' is written using round brackets while the other two are incorrect as they enclose essential words in the bracket.

Part 1:

Let x represent orders of fries and y represent burgers, then the system of equations that models the given situation is given by:

4x+2y=14 \\ 3x+y=9


Part 2:

The graph of the two equations is attached.

From the graph it can be seen that the point of intersection of the lines representing the two equations is at point (2, 3), i.e. x = 2, y = 3.

Therefore, each order of fries costs $2 while each order of burger costs $3.

Part 3:

Using elimination, first we make the coefficients of y in both equations by multiplying the second equation by 2 and then subtracting the result from the first equation.

i.e.

equation (2) x 2 gives: 

6x+2y=18.

Subtracting from equation (1), we have: 

4x-6x=14-18 \\  \\ \Rightarrow-2x=-4 \\  \\ \Rightarrow x= \frac{-4}{-2} =2

Now, from the second equation,

y=9-3x \\  \\ =9-3(2) \\  \\ =9-6=3

Thus, x = 2 and y = 3.

Therefore, each order of fries costs $2 while each order of burger costs $3.
Ireally really really need the answer you guys this is so important < 3< 3< 3 will give 2
