1. Write a rule that will take the triangle to a congruent triangle. Write your rule as (x,y)

olga nikolaevna [1]

Transforming a shape involves changing the size and/or the location of the shape.

The rule that will take the triangle to a congruent triangle is $(x,y) \to (x,-y)$
The rule that will take the triangle to a figure that is similar is $(x,y) \to (0.5x,0.5y)$ .
The rule that will take the triangle to a figure that is not similar or congruent is $(x,y) \to (0.5x,2y)$ .

<h3>Rigid transformation</h3>

When a shape is transformed by a rigid transformation, then the image of the shape will be congruent to the original shape.

An example of a rigid transformation is a reflection over the x-axis; and the rule is:

$(x,y) \to (x,-y)$

So, a rule that will take the triangle to a congruent triangle is $(x,y) \to (x,-y)$

<h3>Nonrigid transformation</h3>

When a shape is transformed by a nonrigid transformation, then the image of the shape will not be congruent to the original shape, however the original shape and the transformed shape would be similar

An example of a nonrigid transformation is a dilation by a scale factor od 0.5; and the rule is:

$(x,y) \to (0.5x,0.5y)$

So, a rule that will take the triangle to a figure that is similar is $(x,y) \to (0.5x,0.5y)$

However, if the x and y coordinates of the shape are dilated by different scale factors, then the resulting shape would neither be similar nor be congruent to the original shape.

A rule that will take the triangle to a figure that is not similar or congruent is $(x,y) \to (0.5x,2y)$ .

What is the value of x in the equation 7(4x+1)−3x=5x−13?

Citrus2011 [14]

Answer:

x = -1

Step-by-step explanation:

7(4x+1)−3x=5x−13

Distribute

28x +7 -3x = 5x -13

Combine like terms

25x+7 = 5x-13

Subtract 5x from each side

25x-5x +7 = -13

20x +7 = -13

Subtract 7 from each side

20x+7-7 = -13-7

20x = -20

Divide by 20

20x/20 = -20/20

x = -1

You are on a game show and you are given the choice of three doors. Behind one door is a car (the main prize). Behind each of th

makvit [3.9K]

Answer:

You need to switch doors.

Switching the door has higher probability of winning.

Step-by-step explanation:

Consider the provided information.

Suppose there are 3 doors, A, B and C

Behind one door is a car that means the probability of getting a car is 1/3

Suppose you select door A

The probability that the it has a goat is 2/3. That means it is very likely to be a goat behind door A.

The other two door(B and C) are more likely to contain a goat and car.

The host opens another door which has a goat behind it. Let say he open the door B.

Now there is more chance to be a car behind it as compare to the previous choice.

Thus, you need to switch doors.

Switching the doors will gives you 2 in 3 chance of winning while staying with same door will gives you 1 in 3 chance of winning.

Switching the door has higher probability of winning.
