The table can be used to determine the solution of equations, 2x − 2y = 6 and 4x + 4y = 28.A table with 6 columns and 2 rows. The first column, Original System has 2 x minus 2 y equals 6 and 4 x plus 4 y equals 28. The second column, Equivalent System, has 4 x minus 4 y equals 12 and 4 x plus 4 y equals 28. The third column, Sum of equations in Equivalent System, has 8 x equals 40. The fourth column, Solution to System, is blank. The fifth column, New System Using Sum, has 4 x plus 4 y equals 28 and 8 x equals 40. The sixth column, Solution to New System is blank.

Which solution can be used to fill in both blanks in the table?

(2, 5)

(5, 2)
(5, −8)
(−8, 5)

Answers

Answer:

(5,2)

Step-by-step explanation:

2x-2y=6\n4x+4y=28

Column 1 :

2x-2y=6..........(1)\n4x+4y=28........(2)

Column 2 :

Eqn(1) *\ 2

4x-4y=12\n4x+4y=28

Column 3 :

Add the equations.

(4x+4x)-4y+4y=12+28\n8x=40

Fourth column :

8x=40\nx=(40)/(8)=5

Fift column :

4x+4y=28\n8x=40

Sixth column :

Substitute x=5.

4* 5+4y=28\n4y=28-20\n4y=8\ny=2

Hence solution is (5,2).

Step-by-step explanation:

A jar is filled with red, blue, and green marbles. Half of the marbles are red. One third of the marbles are blue. One sixth of the marbles are green. What fraction of the marbles are either red or blue?plz hurry this is due tomorrow and i asked this cause i dont get what it's asking

Answers

It says that 1/3 marbles are blue and 1/2 is red. The question is asking you what fraction is either red or blue. basically " write the number of red and blue marbles in fraction form" so what you should do is add 1/3 and 1/2 and get 5/6. I hope you understand.
5/6 of the marbles are red or blue. Since half of the marbles are red, you can convert that to sixths which would be 3/6. You can also convert the number of blue marbles into sixths, and 1/3 is equal to 2/6. When you ad the number of blue marbles to the number of red marbles, you get 5/6. I hope this helps you understand the question better.

Answer:

I think we're probably talking about a right triangle. So just find the adjacent side and the hypotenuse.

Step-by-step explanation:

Once we are considering x \in \mathbb{R}, the range of  \text{cos}(x) is [1, -1]. Therefore, $(42)/(41) $ is not true.

In this exercise, we may have

$\text{cos}(x)=(x)/(r) =(x)/(√(x^2 +y^2) ) $

Considering the trigonometric functions beyond the unit circle.

Or considering the definition in the right triangle:

$\text{cos}(x)=\frac{\text{adjacent}}{\text{hypotenuse}} $

Whats the answer for name the value of each 2 in 222 222

Answers

Answer:

222222=2* 100000+2* 10000+2* 1000+2* 100+2* 10+2* 1        

Step-by-step explanation:

Given : Number 222,222.

To find : Name the value of each 2 in the number?

Solution :

The place value system is

Hundred Th.   Ten Th.    Thousand     Hundred   Tens    Ones

     2                  2                    2              2             2           2

The value of each 2 is

222222=2* 100000+2* 10000+2* 1000+2* 100+2* 10+2* 1

222222=200000+20000+2000+200+20+2
