-6x -6y = 66 2x + 4y = -32​

Answer:

(23/2, 1/2)

Step-by-step explanation:

Let's solve this system through elimination by addition/subtraction:

Divide all three terms of the first equation by 3.  This results in the equivalent system

-2x - 2y = 33

2x + 4y = -32

Combining like terms results in:

2y = 1, and so y = 1/2.

Let's use the first equation and y = 1/2 to find x:

-6x - 6(1/2) = 66

This becomes -6x - 3 = 66, or -6x = 69, or x = -69/6 , or x = 23/2

The solution is thus (23/2, 1/2)

How can you tell the difference between a reflection across the y=x line, and a 180 degree rotation?
hammer [34]
Here are reflection and rotation rules for coordinates. If you look at y=x and the one for 180 degrees you'll see the difference. It's hard to remember it but just study it and you'll be fine. :)
