The will be A'(0, 20), B'(20, 10) and '(-10, 0). Transformation is the of a point from its to a. Types of transformation are reflection, translation, rotation and dilation.
What is transformation?
When a function is transformed, the graph's curve either "moves to the left/right/up/down," "expands or compresses," or "reflects." For instance, by simply moving the graph of the function g(x) = x2 up by 3 units, the graph of the function f(x) = x2 + 3 is obtained. Function transformations are very useful for graphing functions without having to start from scratch because they allow you to move, expand, compress, or reflect the curve. In this article, we will examine the guidelines for function transformations as well as examples of how to transform various function types.
Let ABC be a with coordinates A(0, 2), B(2, 1), C(-1, 0).
The coordinate of points A, B, C will change by below rule
(x, y)↔(10x, 10y)
where 10 is the scale factor.
∴A(0, 2) ↔A'(0, 20)
B(2, 1) ↔B'(20, 10)
C(-1,0) ↔C'(-10, 0)
Hence, will be A'(0, 20) ,B'(20, 10) and C'(-10, 0)

In thi triangle, angle W equal (3x-24) degree, and angle C equal (4x-11) degree, and angle T equal 2x degree, what doe angle W equal?
The angle W equal to 24.3
In a triangle sum of three angles is equal to 180
W = (3x-24) degree
C = (4x-11) degree
T = 2x degree
3x-24+4x-11+2x=180
9x-35=180
9x=180-35
9x= 145
x=16.1
substitute the value of x in W equation
W = 3(16.1)-24 = 24.3

the quadratic equation x2 mx n has roots twice those of x2 px m, and none of m, n, and p is zero. what is the value of n/p?
The value of n/p is 8.
What is quadratic equation?
A quadratic equation in algebra is any equation that can be written in standard form as where x is an unknown and where a, b, and c denote known numbers, where a ≠ 0.
Let, for x^2 + mx + n = 0
⇒ x = 2α or 2β
From the given condition,
for x^2 + mx + n = 0 ⇒ x = α or x = β
Then,
2(α + β) = -m ..(1)
4αβ = n ..(2)
and α + β = -p ..(3)
αβ = m ..(4)
From equation (1) and (3),
-m/2 = -p
⇒ p = m/2
and from equation (2) and (4),
n/4 = m
⇒ n = 4m
Therefore,
n/p = 4m / (m/2) = 4 x 2 = 8
Hence, n/p = 8.

find x, y and z HELPPP
Answer:
x = 30 degrees
y = 15 degrees
z = 150 degrees
Step-by-step explanation:
Finding x:
2x + 90 + x = 180
3x + 90 = 180
3x = 90
x = 30
x and 2y are alternate interior angles, which means that they are congruent:
x = 2y
30 = 2y
15 = y
x and z are same side interior angles, which means that they are supplementary:
x + z = 180
30 + z = 180
z = 180 - 30
z = 150

The per capita consumption (in pounds) of all poultry in a country is approximated by the function C(x) = 2.97x +92.19, where x is the number of years since 2014. Find and interpret C(1)
By evaluating the function in x = 1 we get:
C(1) = 95.16
This means that the per capita consumption of all poultry in 2015 was 95.16 pounds.
How to find C(1)?Here we have the linear function:
C(x) = 2.97*x+ 92.19
We know that it models the consumption of all poultry in a country as a function of x, the number of years since 2014.
Then C(1) will be the consumption of all poultry in that country one year after 2014 (this would be on 2015).
To evaluate we just need to replace the variable x in the equation by 1, we will get:
C(1) = 2.97*1+ 92.19 = 95.16

Ruby purchased 3 dozen eggs. She paid $10.00 fo 6 eggs. Ruby decided to resell the 3 dozen eggs for $2.00 per egg. Unfortunately 0.25 of tue egss were broken. She proceeded to sell the remaining unbroken eggs. Did she make a profit or loss?
Answer: A loss of 6 dollars
Step-by-step explanation:
Step 1 is to determine how many eggs she purchased:
3 dozen eggs * 12 eggs per dozen = 36 eggs purchased
Step 2 is to find the cost of the eggs purchased using the information you gave:
(36 eggs / 6) * 10 dollars = $60 purchase price
Step 3 is to find out how many eggs broke which is calculated like this:
36 total eggs * .25 = 9 broken eggs
Step 4 is to find how much money she made from selling the remaining eggs:
(36 total eggs - 9 broken eggs) * $2 per egg = $54 resale
Step 5 is finding the profit or loss:
$54 resale price - $60 purchase price = $ -6 (aka a 6 dollar loss)
in triangle abc, AB=6.2, AC=9.5, and BC=5.1. Which is the smallest angle of the triangle?
The smallest angles of the triangle is angle A
In triangle ABC
The length of the side AB = 6.2 units
The length of the side AC = 9.5 units
The length of the side BC = 5.1 units
The opposite angle of AB is angle C, the opposite angle of AC is angle B and the opposite angle of BC is angle A
We know length of the line is BC which is 5.1 units which is the smallest side of the triangle. Then the opposite angle of BC will be the smallest angle in the triangle ABC
The opposite angle of the side BC is angle A, which is the smallest angle in the triangle
Hence, the smallest angles of the triangle is angle A

Jane solved an equation, but when she checked her answer she saw her solution was incorrect. She knows she made a mistake, but she can’t find it. Where is Jane’s mistake and what is the solution to the equation?
-3(4x - 5) = 6(x + 3) + 10
-12x + 15 = 6x + 18 + 10
-12x + 15 = 6x + 18
15 = -6x + 18
-3 = -6x
1/2 = x
Jane made a mistake in her third step. The solution of the equation is x = - 13 / 18
How to solve equations correctly?An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.
The solve the equation to detect where Jane made the mistake in her solution.
-3(4x - 5) = 6(x + 3) + 10
open the brackets on both sides of the equation
-3(4x - 5) = 6(x + 3) + 10
- 12x + 15 = 6x + 18 + 10
- 12x + 15 = 6x + 28
subtract 6x from both sides of the equation
- 12x + 15 = 6x + 28
- 12x - 6x + 15 = 6x - 6x + 28
-18x + 15 = 28
subtract 15 from both sides of the equation
-18x + 15 = 28
-18x + 15 - 15 = 28 - 15
-18x = 13
divide both sides by - 18
x = 13 / -18
x = - 13 / 18

The input of a function that can be controlled is the independent variable while the output is the dependent variable thus "Number of hours" and "D" are independent while the amount of muscle mass is the dependent variable.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
An input variable that we can control and manage is said to be an independent variable.
For example in function y = f(x) here we can control variable x so it will be an independent variable.
As per the given,
The number of hours we can spend so will be an independent variable.
The input D will be the independent variable.
The amount of mass muscles depends on age so it will be the dependent variable.
Hence "Number of hours" and "D" are independent while the amount of muscle mass is the dependent variable".
