Triangle XYZ is translated by the rule (x + 1, y â 1) and then dilated by a scale factor of 4 centered at the origin. Which stat
marysya [2.9K]

Answer:  Y and Y'' are congruent after the translation, but not after the dilation.

Step-by-step explanation:

We know that we generally prefer rigid transformations if want to create congruent images.

There are three basic kinds of rigid transformations:  

1) rotation 2) reflection 3) translation

So, they all create congruent images.

But a dilation does not create congruent images because it creates an image of similar same shape as the original but not the same size.

Given : Triangle XYZ is translated and then dilated by a scale factor of 4 centered at the origin.

Then, the correct option is "Y and Y'' are congruent after the translation, but not after the dilation."

The value of 1.7y+37 is 14 less than the value of 9.3y–25
Alinara [238K]

Answer: Yes, it is less than, as the value of the first equation is 14, while the second equation is 100.8

Step-by-step explanation:

1.7y + 37 = 14...........equation 1

9.3y - 25 = ?............equation 2

Find the value of y by subtracting 37 from both sides of equation 1

1.7y +37 -37 = 14 - 37

1.7y = -23

Divide both sides by 1.7

y = 13.53

Insert the value of y into equation 2

9.3 (13.53) - 25

125.83 -25

=100.8
