Answer:

(x, y ) → (x - 6, y - 2 )

Step-by-step explanation:

Given

P(- 10, 1 ) → P'(- 16, - 1 )

Note that the x- coordinate of the image is 6 less than the original and

The y- coordinate of the image is 2 less than the original, thus

(x, y ) → (x - 6, y - 2 )

I used the Interior Angles of a Triangle Rule --The sum of all 3 interior angles in a triangle is always 180°.

(3x + 28) + (5x - 18) + 90° = 180°

Now i can get rid of the parentheses and combine like terms.

3x + 5x + 28 - 18 + 90 = 180

8x + 10 + 90 = 180

8x + 100 = 180

Then i subtract 100 from both sides to isolate x.

8x + 100 - 100 = 180 - 100

8x = 80

Then, i divide both sides by 8 to find x.

8x ÷ 8 = 80 ÷ 8

x = 10

Probability - I am struggling to find which sections/numbers to use in order to solve this section of the question. I will give

Cloud [144]

Answer:

Step-by-step explanation:

Looking for P(B|A)

conditional probability formula: A|B= (A∩B)/B

so B|A= (B∩A)/A

B∩A= 19+27= 46

A= 50+19+27+45= 141

46/141= .3262

Question:

aivan3 [116]

Answer:

part A) The scale factor of the sides (small to large) is 1/2

part B) Te ratio of the areas (small to large) is 1/4

part C) see the explanation

Step-by-step explanation:

Part A) Determine the scale factor of the sides (small to large).

we know that

The dilation is a non rigid transformation that produce similar figures

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

Let

z ----> the scale factor

$\frac{CB}{C'B'}=\frac{CD}{C'D'}=\frac{BD}{B'D'}$

The scale factor is equal to

$z=\frac{CB}{C'B'}$

substitute

$z=\frac{4}{8}$

simplify

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

Part B) What is the ratio of the areas (small to large)?

<em>Area of the small triangle</em>

$A=\frac{1}{2}(2)(4)=4\ units^2$

<em>Area of the large triangle</em>

$A=\frac{1}{2}(4)(8)=16\ units^2$

ratio of the areas (small to large)

$ratio=\frac{4}{16}=\frac{1}{4}$

Part C) Write a generalization about the ratio of the sides and the ratio of the areas of similar figures

In similar figures the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In similar figures the ratio of its areas is equal to the scale factor squared
