Figure AAA is a scale image of Figure BBB. What is the value of xxx?

Arada [10]

Answer:

The scale factor from Figure A to Figure B is 1/2

Step-by-step explanation:

The correct question is

Figure B is a scaled copy of Figure A.

What is the scale factor from Figure A to Figure B?

The picture in the attached figure

we know that

A dilation is a non rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional

In this problem Figure A and Figure B are similar

To find out the scale factor, determine the ratio of its vertical corresponding sides

The vertical side of figure A is 4 units

The corresponding side in figure B is 2 units

$\frac{2}{4}=\frac{1}{2}$

The scale factor is less than 1

The dilation is a reduction

therefore

The scale factor from Figure A to Figure B is 1/2

Give the linear system: 3x + 7y = 20 x ? 4y = 9 Identify the values for the elements in the coefficient matrix: A = a11 a12 a21

laiz [17]

Answer: a11 = 3, a12 = 7, a21 = 1, a22 = -4

Explanation:

3x + 7y = 20

x - 4y = 9

A = $\left[\begin{array}{ccc}3&7&20\\1&-4&9\end{array}\right]$

column 1 column 2

row 1: (a11) 3 (a12) 7

row 2: (a21) 1 (a22) -4

N is the in center of △ABC. Use the given information to find NS. NQ=2x NR=3x−2

kramer

Given that N is the incenter of △ABC, NS = 4.

<h3>What is the Incenter of a Triangle?</h3>

The incenter of a triangle is the point of concurrency of the three angle bisectors of a triangle.
The perpendicular distances from each sides of the triangle to the incenter are equal.

Given the image where:

NQ = 2x

NR = 3x − 2

NQ = NR = NS (equidistant from the incenter)

Thus:

2x = 3x - 2

Add like terms

2x - 3x = -2

-x = -2

x = 2

NQ = NS = 2x

Plug in the value of x

NS = 2(2)

NS = 4

Therefore, given that N is the incenter of △ABC, NS = 4.

Idk how to do this plz help me with it

kakasveta [241]

Answer:

I hope this explains it

Step-by-step explanation:

The first box is for the fractions smaller then a whole number for example 2/5

2 is smaller then 5 so you put it in the first box Answers14/17 and 29/30

The second box is for fractions that equal 1 so itself like 9/9 or 2/2 Answers 16/16 22/22

The last box is for fractions bigger then 1 so for example 10/5 ten is bigger then five Answers 18/11 and 25/19
