Flipping a coin should be it
First, the mark down 15% would make the value 85% of the original, so doing 15.99*0.85 gives you 13.59. Then take that and multiply that by 0.5, because of the half price, to get a final price of $6.79
4n3 2m 6m 5n 2n should be written as {<span>4n^3, 2m, 6m, 5n, 2n}
4n^3 stands alone. No other term has this format.
2m and 6m are like terms and can be combined into 8m.
5n and 2n are like terms and can be combined into 7n.

Answer:

Step-by-step explanation:
Given the polynomials:

On Inspection

By the Spanning Theorem
If one vector in S is a linear combination of the others, we can delete it and get a subset (one vector smaller)
that has the same span.
Therefore, since 

are linearly independent because
cannot be written in terms of
.
Therefore, 
Answer is ''there are infinitely many intersection points'' .
Let equation of the line 1 be

As given they are the same line so Russ should interpret that

So, they are coincident and its a consistent-dependent system .Both of them will have same values of y for same value of x .
Therefore they will have infinitely many solutions and hence intersections.
For example Equation of line 1 be 2x +3y = 5 and equation of line 2 be 4x+6y=10 then
therefore, these lines are coincident and have infinitely many solutions .
