Answer: 4
Step-by-step explanation: a is three units away from o and a’ is 9 units away from o. you add 9+3 to get the total distance and divide that number by 3 to get the scale factor. 12/3=4
The scale factor for the given dilation is 3
What is Dilation?Dilation is a transformation of an object which changes its size. if the dilated image is larger then it is called enlargement. If the dilated image is smaller it is called reduction.
If the dilation has the origin as the center of dilation, we can find points on the image formed by dilation by multiplying the coordinates of the original geometric object like triangle multiplying by the scale factor. For scale factor k, the transformation of the dilation is written as : (x, y) → (k x, k y).
The scale factor ,k = coordinate of image / coordinate of original
Given that Triangle ABC is dilated to create triangle A’B’C’ using point O as the center of dilation as shown in the figure
Scale Factor = coordinate of image / coordinate of original
= OA' / OA = 9/3 = 3
Therefore, the scale factor for the given dilation is 3.

Jessi sold half her comic books. Then, she bought 9 more. She now has 11 total. How many did she begin with?
Answer:X+9=11
9-9|11-9
X=2
Step-by-step explanation:When the beginning number is unknown we use “x” to be a place holder. If she got 9 more books we would add 9 to the equation. Finally if 11 is the total, the end of the equation would equal 11.

Please refer to attached for labeling of the diagram:
We have 2 triangles here in the figure:
[tex]\triangle ABC \text{ and }\triangle BDE[/tex].
1. [tex]\angle B[/tex] is common to both the triangles.
Sides AC || DE (parallel sides):
So, Corresponding angles will be equal
2. [tex]\angle A = \angle D[/tex]
3. [tex]\angle E = \angle C[/tex]
So, [tex]\triangle ABC \text{ and }\triangle BDE[/tex] are similar to each other.
Similar triangles have ratio of their sides as equal.
So, [tex]AB : BD = BC : BE[/tex]
[tex]\Rightarrow \dfrac{6+7}{6} = \dfrac{21}{21-x}\\\Rightarrow \dfrac{13}{6} = \dfrac{21}{21-x}\\\Rightarrow 13 \times (21-x) = 21 \times 6\\\Rightarrow 13x = 7 \times 21\\\Rightarrow x = \dfrac{147}{13}[/tex]
Hence, [tex]x = \dfrac{147}{13}[/tex]

C = 0.5n + 5
C=cost (£)
n=number of miles travelled
Calculate the cost of a journey that is 25 miles.
Show your working out and write the answer in the box below.
Answer:
cost of journey of 25 miles = £ 17.5
Step-by-step explanation:
Base on the equation the cost of the journey can be represented as
C = 0.5n + 5
where
C = cost in £
n = number miles covered
To calculate the cost of a journey that is 25 miles we have to insert the value of n as 25 in the equation. Therefore,
C = 0.5n + 5
n = 25
C = 0.5(25) + 5
C = 12.5 + 5
C = £ 17.5
cost of journey of 25 miles = £ 17.5
Find the equation of the line in slope-intercept form containing the points (6, -1) and (-3, 2). y = - 1/3x + 1 y = -3 x -1 y = 9 x -1 y = 1/3x -1
Answer:
y = - 1/3 x + 1
Step-by-step explanation:
(6, -1) and (-3, 2)
Slope = (y2 - y1)/(x2 - x1) = (2 - (-1))/(-3-6) = 3/(-9) = - (1/3)
y-int form is y = ma +b
y = - 1/3 x +b
(-3, 2)
2 = (- 1/3)*(- 3)+ b
2 = 1 + b
b = 1
y = - 1/3 x + 1

The area of a square is (16x2 − 8x + 1) square units. Determine the length of each side of the square by factoring the area expression completely. Show your work.
Answer:
4x - 1
Step-by-step explanation:
Given the area
16x² - 8x + 1
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 16 × 1 = 16 and sum = - 8
The factors are - 4 and - 4
Use these factors to split the x- term
16x² - 4x - 4x + 1 ( factor the first/second and third/fourth terms )
= 4x(4x - 1) - 1(4x - 1) ← factor out (4x - 1) from each term
= (4x - 1)(4x - 1)
= (4x - 1)²
The area of a square = s² ( where s is the length of the side )
s² = (4x - 1)², thus
s = 4x - 1 ← length of side of square
AC=A, C, equals
Round your answer to the nearest hundredth.
Answer:
We have the equation A*C = A
Now, as both sides of the equality are the same thing, we can do the same operation to both sides and the equality will remain true.
We can divide both sides by A and get:
(A*C)/A = A/A
C = 1
So here we finded the value of A.
If A and C are matrices, then C is the identity matrix.
Tamara bought a sweater that was 30 percent off the original price.the original price of the sweater was $80.How much did Tamara pay
Answer:
24
Step-by-step explanation:
Multiply the Price Percentage by the Original Price
Multiply the original price and the percentage that represents the sale price; the result is the sale price of the blazer in dollars: $90 × 0.7 = $63. So if the blazer is on sale for 30 percent off, you'll pay the remaining 70 percent of the price, which is $63.

If triangle ABC was rotated 90 degrees counterclockwise about the origin, what would the ordered pairs be for B'''?
Answer:
Point B is [tex](-1,2)[/tex]
Step-by-step explanation:
Given: A triangle ABC was rotated 90 degrees counterclockwise
To find: coordinates of the point B
Solution:
A triangle is three - dimensional figure that has three sides, three vertices and three angles.
Counterclockwise refers to the direction opposite to the direction of movement of hands of the clock.
As triangle ABC was rotated 90 degrees counterclockwise about the origin, point B is [tex](-1,2)[/tex]
