Geometry you will get 10 points and a friend

The answer is: the Y axis. :I
You reflect it, then you shift the shape 1 unit to the right. For example, Point U is at coordinates, -2, 2. Reflected across the Y axis, it's 2, 2. Then to get to the point that U' is at, you shift your reflected U to the right one unit. That gets you to coordinates 3, 2. Same thing goes for the other Points. Cx Hope this helped!!

51 DVDs

Step-by-step explanation:

Let the number of DVDs and CDs sold be x each.

Initial

Number of DVDs= 86

Number of CDs= 52

After selling

Number of DVDs= 86 -x

Number of CDs= 52 -x

Given that there are 3 times as many DVDs than CDs left,

86 -x= 3(52 -x)

Expand:

86 -x= 156 -3x

Bring x terms to 1 side, constant to the other:

3x -x= 156 -86

Simplify:

2x= 70

Divide both sides by 2:

x= 35

Amount of DVDs left

= 86 -x

= 86 -35

= 51
