The correct answer is option B.
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
A dilation with a scale factor less than 1 and then a reflection
To this point, we've encountered four kinds of symmetry:
Reflection, rotation, translation, and glide-reflection.
These symmetries are rigid motions as a result of they move a figure whereas conserving its size and shape.
All transformations are isometric. Dilation may be a non-isometric transformation. A stretch isn't a similarity transformation.
Dilations, rotations, reflections, and translations are all similar transformations. Since rotation, reflection, and translation are rigid motions, they preserve each size and shape, whereas dilation solely ensures that the form is preserved.
the multiplier is outlined as the magnitude relation of the dimensions of the new image to the size of the previous image.
the middle of dilation may be a mounted purpose within the plane.
supported the dimensions issue and therefore the centre of dilation, the dilation transformation is defined.

Answer:
Hey there!
Unless the smaller object was rotated 360° (in which case the rotation wouldn't have to be mentioned), you can see that all of the lines are still in the same place and that it wasn't rotated at all. This eliminated any answer option that mentions a rotation, which is A and C.
Also, if you count the units of one of the straight lines – for example, line AB and A'B' – you can see that the smaller object is four times smaller than the larger object. In the case of line AB and A'B', line AB is 8 units long and A'B' is 2 units long. This means that the scale factor is .
Lastly, the smaller object was moved from its initial location, which would be in the center of the larger object if it wasn't moved after being scaled down.
The answer will be B, "a dilation with a scale factor of and then a translation."

Answer:
w(16) = 27
Step-by-step explanation:
w(16) = I 16-24 I + 19
w(16) = I -8 I + 19
The straight brackets (forgot their proper names lol) turns any number into a positive version
w(16) = 8 + 19
w(16) = 27
Hope this helps

Then you divide the answer by 100, or move decimal two places to the left. (513/100= 5.13)
Then round to the nearest whole number (5.13 is approximately 5)
Therefore 19%of 27 = 5

Final answer:
To solve this problem, set up an equation using the given weights and solve for 'x' to find the weights of each friend's bag.
Explanation:
To solve this problem, we need to set up an equation based on the given information.
First, let's express the weights of Randall's, Seth's, and Joanna's bags in terms of 'x':
- Randall's bag: 3x - 7 pounds
- Seth's bag: 2x - 10 pounds
- Joanna's bag: 2x + 2 pounds
According to the problem, Randall's and Joanna's bags together weigh 3 times as much as Seth's bag. Mathematically, this can be written as:
(3x - 7) + (2x + 2) = 3(2x - 10)
Solving this equation will give us the value of 'x', which we can then use to find the weights of each friend's bag.

Answer:
Randall=68 pounds, Seth's=40, Joanna's=52
Step-by-step explanation:
Randall's = 3x-7
Seth's = 2x-10
Joanna's = 2x+2
Randall's + Joanna's = 3 (Seth's)
Find X:
- Form into an equation (add parentheses)
- (3x-7) + (2x+2) = 3 (2x-10)
- REmove parentheses on left side
- 3x-7+2x+2 = 3 (2x-10)
- Distribute right side
- = 6x-30
- 3x-7+2x+2 = 6x-30
- Combine like terms
- 5x-5=6x-30
- subtract 5x from BOTH sides (always subtract, add, multiply, and divide both sides at the same time)
- -5=x-30
- Add 30 to BOTH sides
- 25=x
Find how many pounds of trash each friend picked up:
Randall's:
- 3x-7
- plug in x
- 3(25)-7
- Distribute
- 75-7
- = 68
Seth's:
- 2x-10
- 2(25)-10
- 50-10
- = 40
Joanna's:
- 2x+2
- 2(25)+2
- 50+2
- =52
Double check your answers:
Randall's+Joanna's= Seth's(3)
68+52=40(3)
120=120
You're good to go!
