Answer:B

Step-by-step explanation:

A reflection of the line segment across the line y = - x, will produce an image with endpoints at (- 4, 1) and (- 1, - 4).

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

We know, A reflection across the 180° about the origin transforms

(x, y) to (-x, - y)

Therefore A line segment has endpoints at (-1, 4) and (4,1) will have an image at  (- 4, 1), and (- 1,- 4) is a reflection of the line segment across the line y = - x.

Answer:

8.513

Step-by-step explanation:

The round off to the number at three decimal places will be 8.513.

When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done.

A number can be rounded off to its lower value if the number after the decimal is between 0 and 4. The number will be rounded off to its higher value if the number after it is between 5 and 9.

The round-off to the number 8.51348434552 to the three decimal places will be 8.513.

Answer:

R+239=3501

Step-by-step explanation:

Add the three 1,167 values together and you get 3,501. Then, because we know a portion of the three blocks is equal to 239, add it so when we solve for R, 239 is subtracted from the total.

As for solving it,

Subtract 239 on both sides, and R is 3501-239 = 3262

Answer:

  5) 76°

  7) 34°

Step-by-step explanation:

5) An angle bisector creates two congruent angles, so ...

  ∠WUV = 2(∠1)

  9x +4 = 2(5x -2)

  9x +4 = 10x -4

  8 = x

Then ...

  ∠WUV = 9(8) +4 = 76

The measure of angle WUV is 76°.

__

7) An angle bisector creates two congruent angles, so ...

  ∠1 = ∠2

  2x -3 = x +7

  x = 10 . . . . . . . . add 3-x

Then ...

  ∠XVW = 2(∠2) = 2(10 +7) = 34

The measure of angle XVW is 34°.

The inequality that represents this graph is y < 2x + 2.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

The dotted line represents strictly less than or greater than.

From the graph, we can conclude that when x = 0, y = 2, and when x = 1 y = 4, and values of y are strictly less.

∴ The inequality that represents this graph is y < 2x + 2.

Sum of triangle: 180

So we know that:

7x + 3x + 8 + x + 7 = 180

Combine like terms:

11x + 15 = 180

11x = 165

x = 15

Plug in for x in order to find the angles.

Answer:

  m∠I = 22

  m∠J = 53

  m∠K = 105

Step-by-step explanation:

m∠I = (x + 7)

m∠J = (3x + 8)

m∠K = (7x)

m∠I + m∠J + m∠K = 180°

(x + 7) + (3x + 8) + (7x) = 180

x + 7 + 3x + 8 + 7x = 180

11x + 15 = 180

11x = 165

x = 15

m∠I = 15 + 7 = 22

m∠J = 3(15) + 8 = 53

m∠K = 7(15) = 105

Step-by-step explanation:

Using a geometric sequence, it is found that the number of black squares in the first five figures of the Sierpinski Carpet is of 4681.

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio r.

The nth term of a geometric sequence is given by:

[tex]a_n = a_1r^{n-1}[/tex]

In which [tex]a_1[/tex] is the first term.

The sum of the first n terms of a sequence is given by:

[tex]S_n = \frac{a_1(1 - r^n)}{1 - r}[/tex]

In this problem, the parameters are: [tex]a_1 = 1, r = 8, n = 5[/tex], hence:

[tex]S_n = \frac{1(1 - 8^5)}{1 - 8} = 4681[/tex]

The number of black squares in the first five figures of the Sierpinski Carpet is of 4681.
