A pair of equations is shown below: y = 8x − 9 y = 4x − 1 Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution. (5 points) Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer. (5 points) Part A, so to start off this problem i used substitution... after, this is some of the math used to solve this promblem y = 8x - 9 y = 4x - 1 8x - 9 = 4x - 1 ... so after that u can see i was just using substitution so now lets move on to the next step..

see below

Step-by-step explanation:

y = 8x − 9

y = 4x − 1

Since the two equations are both equal to y set them equal to each other

8x -9 = 4x-1

Subtract 4x from each side

8x - 9 -4x = 4x-1-4x

4x -9 = -1

Add 9 to each side

4x-9+9 = -1+9

4x = 8

Divide by 4

4x/4 = 8/4

x=2

Now find y

y =4x-1

y = 4(2) -1

y = 8-1

y = 7

(2,7)

The solution to the system of equations is where the two lines intersect.  When  the two lines are graphed, they will intersect at (2,7)

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes.
