Answer:

(x+4, y+3)

Step-by-step explanation:

First, choose a point to follow (I chose C). The coordinates of C are (-2, -5). The coordinates of C' are (2, -2). To get to 2 from -2, you have to add 4. Move left or right because it's on the x-axis. Since it's moving you the right, it is positive. So, x+4 is the first part. To get from C to C', you have to move up to follow the y-axis, meaning another positive. Counting the units from (2, -5), because that is the point after x+4, there are 3 units. So, (x+4, y+3).

Answer:

BD = 12 :)

Step-by-step explanation:

Alright, we'll need the Pythagorean theorem for this!

So, the length of AC is 10. That means the lengths of AD and DC are both half of that, which is 5 :)

DC = 5

We already know that BC = 13, so we can plug in these values into the pythagorean theorem for the right triangle BDC:

BD^2 + DC^2 = BC^2

BD^2 + 5^2 = 13^2
