Substitution doesn't work for this, but elimination does.
-6x-8y=-20 +6( x+6y=-6)
-6x-8y=-20 + 6x+36y=-36
-6x and 6x cancel each other, add -8 and 36 to get 28, and -20 and -36 to get -56.
28y=-56
divide by 28 on both sides.
Y= -2
Then substitute y into one of the equations.
x+6(-2)=-6
x-12=-6
x=6
The ordered pair is (6,-2).

Step-by-step explanation:
Answer:
1. First choice, 1/2
2. First choice, 1/2
Step-by-step explanation:
3 odd numbers on a dice, so 3/6 = 1/2
12 numbers, 1- 12, the even numbers are 2, 4, 6, 8, 1-, and 12. 6 out of 12 = 6/12 = 1/2
Okay, so basically you are going to use the Pythagorean Theorem which states: If a right triangle has sides a and b and hypotenuse c then a2+b2=c2.
You already have the distance between AC and BC so you want to figure out the distance between AB. All you have to do is plug in the information. If you draw out a picture, it will help you to visualize it.
I believe the answer is 26...
