Answer:

x=-3

y=2

Step-by-step explanation:

To solve this problem you can use the elimination method:

- Multiply the second equation by -6:

(-6)5x+y=-13\\-30x-6y=78

- Add both equations:

6x+6y=-6\\-30x-6y=78\\-------\\-24x=72\\x=-3

- Substitute the value of x into one of the original equations and solve for y:

6(-3)+6y=-6\\-18+6y=-6\\6y=12\\y=2

Answer:

x = -3 and y = 2 is the solution.

Step-by-step explanation:

we have given system of equations:

6x+6y=-6           equation I

5x+y = - 13          equation II

we solve this system of equation  by using elimination method.

multiplying the equation II by - 6.

(-6)5x + ( -6 )y = ( - 6 ) (- 13 )

-30 x - 6 y = 78      equation  III

adding equation   I and III we have

6x + 6y = - 6

-30x -6y =78

_____________

- 24 x = 72

x =  - 3

substituting value of x in any of original equations and solve it for y.

we are putting the value of x in equation I and solve it for y

6( -3 )+ 6y = -6

-18 + 6y = -6

6y = 12

y = 2

so, x = -3 and y = 2 is the solution of given system of equations.

Jakub wants to build a new shed.
Effectus [21]

Answer:

<h2><u><em>74 m</em></u></h2>

Step-by-step explanation:

<em>Jakub wants to build a new shed.</em>

<em>The area of the shed is 37 m².</em>

<em>The width of the shed is 5 m.</em>

<em>What is the length of the shed?</em>

to find the side, having the area, you need to use the inverse formula Area = W * L

so

L = A: W

L = 37 : 5 =<u><em> 7.4 m</em></u>

Use the two given functions to write y as a function of x<br><br> y=3m-5, m=x+5/3
Romashka [77]

y=3x

Step-by-step explanation:

y=3x-5

but

m=x+5/3

replace m in 3m to 3(x +5/3)

i.e

y=3(x+5/3)-5

y=3x +5-5

y=3x

Consider the following dot plots.
motikmotik
The <u>correct answer</u> is:

A) The medians are both between 10 and 14 emails.

Explanation:

The <u>mode </u>is the easiest measure to find of a data set.
The <u>mode </u>of a data set is the data value that appears the most often.  In plot A, there are 3 dots at 10 and 3 dots at 15; this means the modes are 10 and 15.

In plot B, there are 3 dots at 5 and 3 dots at 15; this means the modes are 5 and 15.

They <u>do not have the same modes</u>.

The <u>median </u>of a data set is the middle value.  There are 10 dots in each dot plot; this means the medians will each be between two data points.

For plot A, we can see that the middle value is between 10 and 15.  
For plot B, we can see that the middle value is between 10 and 15.

This means that choice A is correct, the medians of both are between 10 and 14.

If you can help with any of these I would really appreciate it. Even if you could just explain what to do. Thank you :)
densk [106]

Answer:

number 3, if s equals 5mm, then all of the sides on the square would be 5mm, because it is a square. thus making the area 25mm, and the perimeter 20 mm.
