Using Pythagoras theorem
|AB|*2=|d/2|=(5*2)+12*2
AB*2=25+144
AB=13
D/2= r=6.5cm
tan¥=6.5/5
tan¥=1.3
¥=tan inverse of (1.3)
¥=52.43 degrees
1) -13 = -4a - 2b + c
-13 = -2(2a + b) + c
2) 3 = 4a + 2b +c
3 = 2(2a + b) + c
3) 5 = 16a + 4b + c
5 = 4(4a + b) + c

Answer: -10
Step-by-step explanation: For this problem we will solve the numbers in order.
-4 - 5 + 4 + (-5)
First subtract -4 - 5, which will give you -9. Then add -9 to 4, which will give you -5. Lastly add -5 plus -5, which will give you an answer of -10.
The blue yard is 8 Each below
Okay so you need to write down all of your original points, for example:
<A (1,1)
<B (3,4)
<C (5,1)
so now for each of those coordinates you would subtract four from each X and add 3 to each Y. For example:
Original Cord.: Translated Cord.:
<A (1,1) <A' (-3,4)
<B (3,4) <B' (-1,6)
<C (5,1) <C' (2, 4)
------------------------------------------------------------------------
So just follow my steps but with your points, then graph both the original coordinates and the translated coordinates. AND DON'T FORGET TO LABEL THE POINTS LIKE I DID WHEN GRAPHING!!!!!!!!
