N is at least -2, but less than 3
|-x + 2| = 12
|-x + 2| = 12 or |-x + 2| = -12
-x + 2 = 12 or -x + 2 = -12
- 2 - 2 - 2 -2
-x = 10 or -x = -14
-1 -1 -1 -1
x = -10 or x = 14
Solution Set: {-10, 14}
Hint:
Ax+By+C= D
is parallel to
Ax+By+C= E
So in this case,
2x−9y+4z=5
is parallel to
2x−9y+4z=k
for any real number k
Answer:B
Step-by-step explanation: dy/dx = (1--4)/(-10-0)
= 5/-10
=-1/2
