The pre-image and image of what transformation are not congruent?
O A. dilation
O B. reflection
O C. translation .
O D. rotation​

Answers

Answer:

Option A

Step-by-step explanation:

Options B, C, and D are examples of ridged transformations. Ridged transformations are transformations that  keep the pre-image and image congruent.

A dilation would change the actual size of the pre-image to make the image, so they would be not congruent in a dilation.

Hope this helps.

The correct options are Reflection, Translation and Rotation​.

What is transformation?

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure.

Reflection, Translation and Rotation​ are examples of rigid transformations, and we know that a rigid transformation is a transformation that doesn't change the size or shape of a geometric figure, a special kind of transformation that doesn't change the size or shape of a figure.

There are three different types of transformations: translation, reflection, and rotation.

Whereas,

A dilation would change the actual size of the pre-image to make the image, so they would be not congruent in a dilation, it can enlarge or shrink the image.

Hence, Reflection, Translation and Rotation​ are the transformation which preserve the preimage.

) The price of a watch is marked Rs 11,250. When it is sold allowing 20% discount,
20% profit is made. By what percent is the discount to be reduced to increase the
profit by 3%?​

Answers

Step-by-step explanation:

the first step is to find the cost price

when 20% discount=

11250*80/100= 9000

the 20% discounted price is 9000

there is still a 20% profit in this 20% discount

so Cost.Price *120/100=9000

Cost price= 7500

now its asking for discount percentage at 3% profit so first calculate price after 3% profit

7500*103/100= 7725

so discount on rs11250 required to produce 3% profit=

11250*x/100=7725

x= 68.7% discount

Step-by-step explanation:

If x + y = z, then z - y = x and z - x = y. Since 260 + x = -27, then -27 - 260 = x.

You can change the signs for a moment but you need to change them back at the end. 27 + 260 = 287, flip the signs, -27 - 260 = -287.

Step-by-step explanation:

The independent variable is x

The dependent variable is y

The domain is the range of values of x

That will be 1-4

Now let’s get the range, the range just represent the y-values of the terms in the domain

at x = 1

y = 0.75(1) + 2 = 2.75

at x = 4

y = 0.75(4) + 2 = 3 + 2 = 5

Answers

*see attachment

Answer:

D. Output = 6 - Input

Step-by-step explanation:

The output is the y-value, while the input is the x-value. The coordinates are represented as (x, y), and are graphed in the figure attached below.

Let's consider the function and see which rule best describes the function.

Considering the point (1, 5), the rule, output = 6 - input, applies.

Let's check it out:

Output is 5, input is 1. Substitute 1 as input into the rule, Output = 6 - input, and see if it would give you 5 as output:

Output = 6 - 1

Output = 5

If you try another coordinate pair of the function, the same rule will apply.

Therefore, the best answer is D. Output = 6 - Input

1

The required greatest common factor(GCF) of 35 and 26 is 1.

What is the Greatest Common Factor (GCF)?

The greatest Common Factor is defined as the greatest number that is a factor of both numbers when two numbers are involved.

A number that divides into another number completely is said to be a factor.

The numbers are given in the question, as follows:

35 and 26

We have to determine the greatest common factor of 35 and 26

Prime factorization of the numbers:

35 = 5 × 7

26 = 2 × 13

GCF(35, 26)

= 1

Hence, the required greatest common factor of 35 and 26 is 1.

Hi :)

A) 4x = 48: x= 12
B) 2x -6 = 18 x=12


4x - 12 = 36

Add 36 and 12 to get 48
4x=48

Divide both sides by 4
