We could rewrite

2x + 3 = y

-4y + 8x = -12

as

2x - 1y = -3

8x - 4y = -12

We need to compare these two results. Do they represent the same equation or two different equations? Dividing the 2nd equation by 4 results in 2x - y = -3, which is indeed exactly the same as the first equation. Because of this, we have two straight lines that are superimposed; one lies right on top of the other. Thus, this system has an infinite number of solutions.

The diagram shows the net of a juice box. The box is a rectangular prism.
Hoochie [10]

Answer:

269.6 square centimeters

Step-by-step explanation:

<u><em>The correct question is</em></u>

The diagram shows the net of a juice box. the box is a rectangular prism. what is the surface area of the juice box? 6.4 cm 4 cm 10.5 cm

we know that

The surface area of a rectangular prism is equal to

SA=2B+PH

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

we have

L=6.4\ cm\\W=4\ cm\\H=10.5\ cm

<em>Find the area of the base B</em>

B=LW

substitute the given values

B=(6.4)(4)=25.6\ cm^2

<em>Find the perimeter of the base P</em>

P=2(L+W)

substitute the given values

P=2(6.4+4)=20.8\ cm

<em>Find the surface area</em>

SA=2B+PH

substitute  

SA=2(25.6)+(20.8)10.5=269.6\ cm^2

Which choice most effectively combines the
shepuryov [24]

The subject-verb agreement: "Writing as" effectively combines the sentences at the underlined portion.

<h3>What is a Subject-Verb Agreement?</h3>
  • The grammatical principle of the subject-verb agreement states that a sentence's subject and primary verb must agree.
  • Particularly, singular subjects use singular verbs, whereas plural subjects use plural verbs.
  • There must be an agreement between the number of subjects and verbs (singular or plural).
  • This means that if a subject is singular, then the verb must likewise be singular, and if a subject is a plural, then the verb must also be numerous. verbs DO NOT include "an, s" in their single forms.

Therefore option (A) is the correct answer.

To learn more about Subject-Verb Agreement, refer:

The underlined sentence is:

Also, studies have found that those students who major in philosophy often do better than students from other majors in both verbal reasoning and analytical <u>writing. These results</u> can be measured by standardized test scores. On the Graduate Record Examination (GRE), for example, students intending to study philosophy in graduate school have scored higher than students in all but four other majors.

FOR BRAINLIEST ANSWER ONLY:<br><br> 2.<br><br> 3.<br><br> 4.<br><br> 6.
nasty-shy [4]

Answer:

2. x = 2 & y = 4

3. x = 4 & y = 2

Step-by-step explanation:

2. x + y = 6

  2x + y = 8  (multiply the first equation by -1,  so you can eliminate the ys)

- x - y = -6

2x + y = 8  (now add the variables together)

x = 2 (plug in x in one of the equations to find out y)

x + y = 6

(2) + y = 6

-2           -2

y = 4

3. 3x + y = 14

          x = 2y (plug in x into the first equation and solve it for y)

3(2y) + y = 14

6y + y = 14

7y = 14

y =  2  (plug in y in one of the equations to find out x)

x = 2y

x = 2(2)

x = 4

4.  One number (x) is 2 more (+2) than twice (times 2) as large as another. their sum is 17. Find the numbers.

2x + 2 = 17 (solve for x)

     -2     -2

2x = 15

x = 7.5

6. 7 (4x + 1) - (x + 6) (start by distributing 7 into the first parenthesis)

  (28x + 7) - (x + 6) (do the same to the other parenthesis by distributing -1)

  (28x + 7)  (-x - 6) (and now just combine like terms)

   28x + 7 - x - 6

   28x - x + 7 - 6

   27x + 1

i hope this helped! if you have any question, pls let me know!
