Why is graphing not always the best option for solving systems?

Best Answer:  When graphing and locating the point of intersection & hence the solution, you might find that this point does not have integer co ordinates. You would have to estimate the approximate coordinates. Hence, the algebraic methods are preferred, as you could then state the exact co ordinates like (5/3, 4/9).

1, Might not be precise 
2, Can be hard to plot the graphs
3, If there are many solutions that will be really hard to plot sometimes. 

This is just from the top of my head.

Use the elimination method to solve this system.
leva [86]

Answer:

The solution for this system is: x = -1, y = 1

Step-by-step explanation:

The problem states that we have to solve this system by the elimination method

In the elimination method, we transform the system in such a way that one variable can cancel each other. With this, we find the result of the other variable. Then, we can replace the variable we found in any of the equations, and we have the value of the variable that we had initially canceled.

In this problem, we have the following system:

1) -6x + 5y = 1

2) 6x + 4y = -10

If we add equations 1) and 2), the variable x is going to be eliminated

1) + 2)

-6x + 6x + 5y + 4y = 1 - 10

9y = -9

y = \frac{-9}{9}

y = -1

Now, we can replace the value of y in any of the equations, to find x:

I will replace in equation 2)

6x + 4y = -10

6x + 4(-1) = -10

6x = -6

x = \frac{-6}{6}

x = -1

The solution for this system is: x = -1, y = 1

<em>Your income determines your credit score</em>

False.

Your income can sometimes affect your credit score, but it's not based on it. Your credit score is based on your Payment history, Credit history, and debt.
