Answer:
15
Step-by-step explanation:
|-7|=7
|8|=8
7+8=15
Answer:
Part 1: [ -4 = -8 ]
Part 2: Inconsistent
Step-by-step explanation:
<u>Part 1</u>
1. Move all terms that don't contain x to the right side:
3x - 6y+6y = -12+6y
= 3x = -12 + 6y
2. Isolate x:

x = -4 + 2y
3. Substitute the new expression into the original:
-4 + 2y - 2y = -8
4. Simplify:
-4 + 0 = -8
[ -4 = -8 ]
<u>Part 2</u>
The two solutions are not equal in value, so, we can conclude that the system of equations has no solution, or is inconsistent.
hope this helps!
Answer:
Parallel
Step-by-step explanation:
It is so easy being parallel is two lines.
Y=mx+b
b is the y intercept, and the y intercept is 1.5, (I graphed it), and the slope of the line is (-6/-7), and since they are both negative, 6/7.
so: y=6/7x+1.5
