Using the given transformations, namely translation and dilation, the correct statement is given as follows:

Segments YZ and Y''Z'' are proportional after the dilation and congruent after the translation.

<h3>Translation</h3>

The translation rule in this problem is given as follows:

(x, y) -> (x + 1, y - 1).

Meaning that the triangle was shifted:

  • One unit right, due to x -> x + 1.
  • One unit down, due to y -> y - 1.

The only change with the dilation was in the position of the triangle, hence the translated triangle is congruent to the original triangle.

<h3>Dilation</h3>

The triangle was dilated by a scale factor of 4, meaning that the coordinates of each vertex of the triangle is multiplied by 4, changing the side lengths of the triangle, thus the dilated triangle is not congruent to the original triangle.

The angles keep the same measure for both cases, translation and dilation, hence the first two statements are incorrect.

The change in the side lengths is proportional, due to the scale factor of 4, hence the correct statement is:

Segments YZ and Y''Z'' are proportional after the dilation and congruent after the translation.

<h3>What is the missing information?</h3>

The correct options are missing and are given by the image at the end of the answer.

Tashia ate 1/3 of a pizza, and Jay ate 3/8 of the same pizza. What fraction of the pizza was eaten?
Sauron [17]
This is basically saying how much of the pizza did Tashia and Jay both ate, thus combining their portions together.

1/3 + 3/8 = fraction of pizza eaten

To add fractions, you must have a common denominator. Which is 24 in this case because 3*8 = 24.

So you multiply 1/3 with 8 and multiply 3/8 with 3.

1/3*8= 8/24
3/8*3= 9/24

Now you add the fractions.
8/24+9/24= 17/24. You add the numerator, the denominator stays the same.

17/24 of the pizza was eaten.

What is the volume of a cylinder with a diameter equal to 6 and height equal to 8? Let pi = 3.14.
Sindrei [870]
Volume of a cylinder is pi*(radius)^2* height. pi is 3.14 and radius is half of diameter which would be 3. height is 8. Thus volume of a cylinder in your case is pi*9*8 or 72*pi which is approximately 226.19

If f(x)= 3x + 10x and g(x)=5x - 3 find (f+g)(x)
Illusion [34]

Answer:

18x-3

Step-by-step explanation:

f(x)= 3x + 10x

g(x)=5x - 3

f(x)+g(x) = 3x + 10x + 5x - 3

Combine like terms

             = 18x -3
