Answer: 
Step-by-step explanation:
I assume that you need the new coordinates of the point after the rotation centered at the origin.
For this exercise it is important to remember the definition of "Rotation".
A Rotation is defined as a transformation which a figure is rotated about a fixed point known as "Center of rotation".
The figure before the transformation is called Pre-Image and the figure obtained after the transformation is called "Image".
The 180 degree rotation about the origin Rule states that:
→ 
Therefore, knowing that the given point (5,4) is rotated 180 degrees clockwise about the origin, you can conclude that its Image is:

Answer: 21
Step-by-step explanation:
1/3 = 7
7 * 3 = 21
1/3 = 7/21
Answer:
$455.5
Step-by-step explanation:
200+(0.7x365)
1: perpendicular
2:parallel
3:parallel
4:neither

Let's solve for x and z ~

[ they form co - exterior angle pair ]


now, it's time for x :
First angle z is equal to its vertical opposite angle, and then that angle forms co - interior angle pair with (3x - 28)






That's all... let me know if you have questions ~
