The transformations done are option A. A reflection over the y-axis, then a reflection over the x-axis
Step-by-step explanation:
Step 1:
First, we plot the points of triangle ABC and A''B''C''.
The points of triangle ABC are A (-8, -5), B(-4, -3), and C(-4,-7).
The points of triangle A''B''C'' are A'' (8, 5), B'' (4, 3), and C'' (4,7).
The points of both triangles ABC and A''B''C'' are the same values but different symbols for x and y values.
Step 2:
If a shape is reflected across an axis, the values remain the same but the symbols vary according to the quadrant.
If a shape is translated, all coordinates of all the points vary accordingly.
As triangles ABC and A''B''C'' have exactly the same coordinates it means that two reflections have occurred but no translations have occurred.
So the answer is the option with two reflections. So option A. A reflection over the y-axis, then a reflection over the x-axis is the answer.
Hello!
I am happy to see your question posted here on Brainly. Let me see if I can help.
So I’m assuming you are wanting to know the new price of the car after the 12% is added.
Let’s get to work.
So what we want to do here is use addition.
33,600 + 12% = 37,632
And that is your answer! $37,632 is the new price of the car.
Have a wonderful day and thank you for using Brainly!

Answer:
= 1872x^2 - 1960q^2 - 1386xq
Step-by-step explanation:
First you should distribute.
(24x * 56q), (24x * 78x), (-35q * 56q), (-35q * 78x)
=1344xq + 1872x^2 - 1960q^2 - 2730xq
Now you combine like terms.
= 1872x^2 - 1960q^2 - 1386xq
**NOTE that (^2) means "squared"
Since there are no more like terms that is your final answer. I hope this helps love! :)
Answer:
This is the case ASA, with 2 triangles are congruent (ABD and CBE)
ABD = CBE because
Angle BAD = Angle BCE (as pic)
AD = CE (as pic)
Angle ADB = Angle CEB
Step-by-step explanation:
Angle ADB = Angle CEB because
ADB = 180 - BAD - B
CEB = 180 - BCE - B
BAD = BCE (as pic)
