Answer:
D. (x, y) → (x, −y)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.
The orientation shows how an object is arranged. Rotation, translation and dilation preserves orientation while reflection does not preserve orientation.
The transformation (x, y) → (4x, 4y) shows the dilation by a scale factor of 4. Dilation preserve orientation.
The transformation (x, y) → (−y, x) shows the rotation of a point 90 degrees counterclockwise. Rotation preserve orientation.
The transformation (x, y) → (14x, 14y) shows the dilation by a scale factor of 14. Dilation preserve orientation.
The transformation (x, y) → (x, −y) shows a reflection over the x axis. Reflection does not preserve orientation.

Answer:
Step-by-step explanation:
The sum of a triangle's interior angles is 180
. From the figure, we can see that one of the angles is a right angle. The remaining two are x and y. By adding these together, we can equate their sum with 180.
x+y+90=180b
Using the equation found in part A and the given equation, we can form a system of equations.
The Solution:
Given:
Each withdrawal by Brandon = $x
ATM charge per transaction = $2
Required:
To find an expression for Brandon's total withdrawal if he withdraws the same amount once a week for 7 weeks.
Step 1:
We shall find the total amount of each withdrawal, that is, the sum of the amount withdrawn and the ATM charge for the transaction.
Step 2:
Finding the required total amount, we have:
Therefore, the correct answers are: [options 2, 3, and 4]
