The given expression is
(m^2*n^-3)/(m^6*n^-1)
Tyrone's approach.
Raising the expression to the 3rd power will not help. It will make the expression more complicated.
Alisha's approach.
(m^2*n^-2)/(m^6*n^-1)
= m^(2-6)*n^(-3+1)
= m^-4*n^-2
= 1/(m^4*n^2)
Alisha's approach wll simplify the expression to 1/(m^4*n^2)
X+y = 6
-y+2+y = 6 ... replace x with -y+2
(-y+y) + 2 = 6
(-1y+1y) + 2 = 6
(-1+1)y + 2 = 6
0y + 2 = 6
0+2 = 6
2 = 6 ... this equation is false
Since the last equation is false, this means that no matter what we pick for x and y, there is no solution. This system is inconsistent. The two lines are parallel (they never intersect to form a solution)

Your answer will be 7A - 42.
I hope this helps!
Answer:
The correct answer is true. A plane formation conditions are: 1) At least three non-collinear points. 2) At least one point and a straight line such that the point should not lie on the straight line. This is the criteria for plane formation
Hope this helps :)
