Answer:

x+2y=12-------(1)

x-2y=3---------(2)

Adding equations 1 and 2

we get

2x=18

x=9

Equation 1

9+2y=15

2y=15-9

2y=6

y=3

The solution of the given system is x=9, y=3

The line of reflection will (always, sometimes, never) be the perpendicular bisector between a preimage and it’s reflected image
frez [133]

Answer:

Step-by-step explanation:

line of reflection: <em>a fixed line directly in the middle of the pre-image and the reflected image. </em>

perpendicular: <em>two lines meeting at a 90 degree angle</em>

bisector: <em>line that divides something into two equal parts</em>

pre-image: <em>the original figure before any transformation or translation has been made</em>

reflected image: <em>the original image after being reflected across the line of reflection.</em>

<em />

Is the line of reflection a line running perpendicular, directly in the middle of the pre-image and the reflected image? Yes, always would be my answer.

Hey there!

The answer to your question is 313/495

To solve this, let's use the equation x = .6323232...

We want to get <u>ONLY THE REPEATING PART</u> on one side of the decimal, so we can multiply the equation by 101:

100x = 6.323232...

Now, we can take the original equation and subtract it from the new equation:

100x = 63.232...

     x =     .632...

 99x = 62.6

Now, divide both sides by 99.

x = 62.6/99

Simplify the fraction:

x = 313/495

Good luck! Hope it helps, and have a great day!
