When a pre-image moves the new shape is called a?

The operation that maps(moves)the preimage onto the image is called a **transformation.**

What is transformation?

An operation that manipulates a polygon or other** two-dimensional **object on a plane or coordinate system is known as a** transformation. **Two-dimensional figures can be transformed **mathematically** in order to travel about a plane or **coordinate system.**

The two-dimensional shape without any transformations is known as a **preimage** or **inverse** image. The transformed figure is shown in the** image**.

In mathematics, there are **five** different transformations:

**Dilation** is the process of an image "shrinking" or "enlarging," depending on the size of the preimage.

**Reflection**: The picture is a preimage that has been reversed; "a flip."

**Rotation:** The picture is the preimage turned around a fixed axis; this is referred to as "a turn."

**Shear: **When a preimage is sheared, all the points along one side remain stationary while all the other preimage points move parallel to that side in proportion to the distance from the given side; this is also known as "a skew."

**Translation:** The image is "a slide" away from the preimage by a fixed amount.

The point (2,-4), (x,y), A, and B all lie on the line. Find an equation relating x and y (Hint: The lope formula)

The point (2,-4), (x,y), A, and B all lie on the line. An **equation** relating x and y is m(x-2)=y+4.

The points (2, -4), (x, y) are **lie** on the line.

The slope formula is the vertical change in y divided by the horizontal change in x, sometimes called rise over run. The slope formula uses two points, (x1, y1) and (x2, y2), to calculate the change in y over the change in x. Slope is a ratio that includes how y changes for every unit increase of x.

The **slope** formula,

m[tex](x_{2}-x_{1})= y_{2}-y_{1}[/tex]

Here, [tex]x_{1} = 2, x_{2}= x, y_{1}= -4[/tex] and [tex]y_{2}= y[/tex]

Now, we have to **substitute** the values in the formula,

The Carnegie children are 3, 24, 18, and 9 years old. What is the median of their ages? what is the mean?

To find the median of a set of numbers, we need to first put the numbers in order from least to greatest. In this case, the ages of the Carnegie children are 3, 9, 18, and 24 years old. Since there are 4 numbers in this set, the median is the average of the middle two numbers, which are 9 and 18. The median of the ages of the Carnegie children is (9 + 18) / 2 = 27 / 2 = 13.5 years old.

To find the mean of a set of numbers, we need to add the numbers together and then divide the sum by the number of numbers in the set. In this case, the sum of the ages of the Carnegie children is 3 + 9 + 18 + 24 = 54 years old. Since there are 4 children, the mean age is 54 years / 4 children = 13.5 years old. Therefore, the mean of the ages of the Carnegie children is 13.5 years old.

**Answer:**

Median: 13.5

Mean: 13.5

**Step-by-step explanation:**

To get the median, take the middle value. Since there are two middle values, add them together and divide them by two.

To get the mean, add all the values together and divide the sum by the number of values. In this instance, mean and median are the same.

In ΔQRS, s = 5.2 inches, ∠S=129° and ∠Q=30°. Find the length of r, to the nearest 10th of an inch.

The **length** of r is 2.4 inches.

What is the **law of sines **?

The **law of sines** specifies how many sides there are in a triangle and how their individual sine angles are equal. The sine law, sine rule, and sine formula are additional names for the sine law.

Given, In ΔQRS, s = 5.2 inches, ∠S=129° and ∠Q=30°

We know that, The sum of all angles of a **triangle** is 180°.

So, ∠Q + ∠R + ∠S = 180°

∠R = 180° - 129° - 30°

= 21°

Now, We also know that the **law of sines** specifies how many sides there are in a triangle and how their individual sine angles are equal.

So, q/Sin Q = r/Sin R = s/Sin S

Or, we can say

r/Sin R = s/Sin S

r/Sin 21° = s/Sin129°

r/Sin 21° = 5.2 / Sin 129°

r = 5.2 × Sin 21°/Sin 129°

What property of congruence is used for the statement AB ≅ AB?

The congruence's **reflexive** characteristic is applied to the statement AB ≅ AB.

In algebra, a number is always equal to itself according to the reflexive **property** of equality. The equality's reflexive quality. Assuming that an is a number, a = a. a=a. We discovered that anything is equal to itself thanks to the reflexive characteristic of equality. This characteristic's formula is a = a. All numbers are equal to one another, according to this property. For instance, three is three.

In mathematics, a set X's elements are considered to be reflexive if there is a **relationship** between each one of them. This can be expressed in terms of relations as (a, a) R a X or as I R, where I is the identity relation on A. As a result, it is said to hold reflexivity and to have a reflexive feature. Every angle, every line, and every figure or shape in geometry are congruent to one another according to the reflexive characteristic of congruence. This **characteristic** is typically employed in proofs of parallel lines and the congruence of two triangles.

The **graph** that represents the **function** f(x) = 4[x] is option C.

Option C is the correct answer.

What is a function?A **function** is a relationship between **inputs** where each input is related to exactly one **output**.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The **outputs** of the **functions** are 3 and 5

The **inputs** of the **function** are 1 and 2.

We have,

f(x) = 4 [x]

[x] is the **greatest** **integer** **function**.

We see that,

f(0) = 4 [0] = 0

f(0.5) = 4 [0.5] = 4 x 0 = 0

f(x) = 0 for **0 ≤ x < 1**

f(1) = 4 [1] = 4

f(1.5) = 4 [1.5] = 4 x 1 = 4

f(x) = 4 for **1 ≤ x < 2**

f(2)** **= 4 [2] = 4 x 2 = 8

f(2.5) = 4 [2.5] = 4 x 2 = 8

f(x) = 8 for **2 ≤ x < 2**

Thus,

The **graph** on option C has the required **coordinates**.

What is median if mean is 48 and mode is 15?

The **median **when the mean is 48 and the mode is 15 is 37.

The median is the value that divides a data sample, a population, or a **probability distribution**'s upper and lower halves in statistics and probability theory.

It could be referred to as "the middle" value for a data set.

For instance, what is the median of our data set if we know that we have a mean of 10 and a mode of 4?

Since the Mean - Mode is 3, we may state that 10 - 4 equals 3. (10 – Median).

According to some algebra, the median of our data is 8 because 2 = (10 - Median).

So, the values are:

Mean = 48

Mode = 15

Formula: Mean – Mode = 3(Mean – Median)

Now, calculate the median using the formula as follows:

48 – 15 = 3(48– Median)

33 = 144 - 3Median

3Median = 144 - 33

3Median = 111

Reason 3:

here are the answer choices for the 3 reasons

(A)associative property of multiplication

(B)commutative property of multiplication

(C)istributive property

(D) simplify

**Answer:**

1. (C) Distributive property | 2. (A) Associative property | 3. (D) Simplify

**Step-by-step explanation:**

Here's my attempt:

**Reason 1:**

The first reason is (C) distributive property of multiplication because you're taking the previous step and spreading it out (distributing it). Here's an example of the distributive property of multiplication:

3(4+7) = 3*4+3*7=12+21=33

This will be the same as solving 3(4+7) using PEMDAS

In this step, you're spreading out the problem the same way as the example shown is doing.

**Reason 2:**

The second reason is (A) the associative property of multiplication. The associative property of multiplication says that changing the grouping of the numbers in a multiplication problem doesn't change the product.

Here's an example:

(6*7)*8 = 6*(7*8)

This way, the step groups together two pairs of factors to solve the last step without changing the product.

**Reason 3:**

The final reason is (D) Simplify because the step doesn't use the commutative property of multiplication. Why not? Because the commutative property of multiplication states that changing the order of factors in a multiplication problem doesn't change the product (note that this is different than the associative property of multiplication). Instead, the last step just simplifies the problem.

Hopefully, you read through my explanation, and it helped. Have a good day :D
