Answer:

x=3

y=1

Step-by-step explanation:

-2x - 7y = -13

3x + 6y = 15

3(-2x - 7y = -13) = -6x - 21y = -39

2(3x + 6y = 15) = 6x + 12y = 30

-6x - 21y = -39

----------------------  The -6x and 6x cancel out, 12 - 21 is equal to 9, 30 - 39 = -9

6x + 12y = 30

Therefore, you can say that -9y = -9 so y = 1

FInally, plug that back into either one of the original equations:

3x + 6(1) =15

3x = 9

x = 3

[tex]9x^2-81=9(x^2-9)[/tex]

Answer:

9(x - 3)(x + 3)

Step-by-step explanation:

Given

9x² - 81 ← factor out 9 from each term

= 9(x² - 9) ← x² - 9 is a difference of squares

= 9(x - 3)(x + 3) ← in factored form

Answer:

Answer:

Costo total= $1.120.000

Step-by-step explanation:

Dada la siguiente información:

Se necesita instalar el piso de una habitacion de forma rectangular cuyas dimensiones son 7 m por 8 m.

Costo por m2=  $20.000

Primero debemos calcular el total de metros cuadrados de la habitación:

Totalm2= 7*8= 56m2

Ahora el costo total:

Costo total= 56*20.000

Costo total= $1.120.000

Answer:

AC=18

Step-by-step explanation:

To find AC, use the Pythagorean Theorem.  Since the longest side (hypotenuse) is known, instead of a²+b²=c², the equation will be c²-a²=b².  12²-8²=b²

144-64=b²

80=b²

√80=√b²

8.94427191=b

That is for one of the two right triangles that make up the tent.  Since there are 2 triangles, 8.94427191 only equals BC or AB.  So, multiply 8.94427191×2=17.88854382 to find the length of AC.

AC= 18

Answer:

look below

Step-by-step explanation:

thing to note:

sin = opposite/hypotenuse

cos = adjacent/hypotenuse

tan = opposite/adjacent

opposite= side across angle you are using

hypotenuse= side across 90 degree angle

adjacent= remaining side

angle B

sin = 6/10

cos = 8/10

tan = 6/8

angle C

sin = 8/10

cos = 6/10

tan = 8/6

hope that helped. let me know if you have any questions:)

Answer:

200r

Step-by-step explanation:

All you have to do is multiply the 10 and 20 to get 200 and then put the r after the 20, so it would look like this 200r

Answer:

x = 16

Step-by-step explanation:

hypotenuse=  a /sin(α)

= 22.62742

= 16√2

So using this to calculate x:

x = √c2 - a2

= √22.627416997972 - 162

= √256

= 16

Hope this helps you :)

Answer: 2,986 m³

Step-by-step explanation: to find the volume, you multiply the length, width , and height. since we're told this is a cube, we know that all sides are congruent, so you do 14.4 x 14.4 x 14.4 which equals about 2985.98. when rounding the solution to the nearest tenths, the answer becomes 2986 m³

If the edge length of the cube is 14.4 meters. Then the volume of the cube will be 2986 m³

Suppose that: The side length of the considered cube is L units. Then, we get:

Volume of that cube = L³ cubic units.

The edge length of the cube is 14.4 meters. Then the volume of the cube will be

Volume = 14.4³

Volume = 2985.98

Volume ≅ 2986 m³

More about the volume of the cube link is given below.

Answer:

[tex]B = (x - 3, y + 4)[/tex]

Step-by-step explanation:

Given

Represent the coordinates of circle A with (x,y)

Translation

Left = 3 units

Up = 4 units

Required

Determine the coordinates of B

When a point (x,y) is translated by h units left, the new point is: (x - h, y)

When a point (x,y) is translated by b units up, the new point is: (x, y + b)

So, when circle A is completely translated to B, the new points of B is:

[tex]B = (x - h, y + b)[/tex]

In this case:

[tex]h = 3\ and\ b = 4[/tex]

So:

[tex]B = (x - 3, y + 4)[/tex]

Answer:

480 People.

Step-by-step explanation:

120,000(0.004) = 480

Answer:

1236 sq. m

explanation:

Side of square field = 100m

Area of the square field = side * side

= 100 * 100

= 10,000 sq. m

A path of 3m wide is built outside and along the boundary.

Side of path = 100(from the side of field) + 3(from the upper side) + 3(from below)

= 100 + 6

= 106 metres.

Area of the along with whole square path with side 106m = side * side

= 106 * 106

= 11,236sq.m

Now, Area of whole square = Areas of square field + area of path

therefore, Area of the path only = 11,236 - 10,000

= 1,236sq.m
