Answer:
B
Step-by-step explanation:
When solving multiple choice problems, a reasonable strategy is to look for ways to identify one answer as good, or other answers as bad.
Here, all of the constant vectors in the equations are different, so we can decide the answer based on that.
The only equation with the correct constant vector is choice B.
_____
The constants in the equations are -4, 1, 9 — the values to the right of the equal sign.
Answer:
n > 3
Step-by-step explanation:
Given
3n + 6 > 15 ( subtract 6 from both sides )
3n > 9 ( divide both sides by 3 )
n > 3
