Answer:
3n = 3 - 3n
<=>
6n = 3
<=>
n = 2
=> This equation has one solution.

Find Slope for Line m:
----------------------------------------------------------------------------------------------------
Two points on the graph: (-4. 3) and (0,-4)

----------------------------------------------------------------------------------------------------
Find Slope for Line n:
----------------------------------------------------------------------------------------------------
Two points on the graph: (1, 2) and (3, -2)

----------------------------------------------------------------------------------------------------
Find Slope for Line k:
----------------------------------------------------------------------------------------------------
Two points on the graph: ( -3 , -3) (4 , 1)

----------------------------------------------------------------------------------------------------
Answer: Since M and N do not have the same slope, they are
not parallel.
Answer: The slope of K is the negative reciprocal of M, therefore they are
perpendicular.

The answer would have to be 5
Answer:
C
Step-by-step explanation:
the solution is at the point of intersection of the 2 lines.
the lines intersect at (1, 4 ) , then
solution to the system of equations is (1, 4 )
Answer:
b)
Step-by-step explanation:
n²+n-42=0
Using mid-term break
n²+7n-6n-42=0
n(n+7)-6(n+7)=0
(n-6)(n+7)=0
Either,
n-6=0 OR n+7=0
n=6 OR n= -7
