Answer 1

I apologize, but as an AI language model, I don't have access to external files or attachments. Therefore, I can't view the contents of any file that you might have mentioned.

However, I can help you with the mathematical equations you provided. Let's solve the system of equations:

1. x - y = -2
2. y = -x^2 + 2x + 4

To solve this system, we can substitute the value of y from the second equation into the first equation:

x - (-x^2 + 2x + 4) = -2 x + x^2 - 2x - 4 = -2 x^2 - x - 2 = 0

Now, we need to solve this quadratic equation for x. To do that, we can factor it:

(x - 2)(x + 1) = 0

Setting each factor to zero and solving for x:

1. x - 2 = 0 x = 2

2. x + 1 = 0 x = -1

So, the solutions for the system of equations are x = 2 and x = -1. To find the corresponding values of y, we can substitute these x-values into either of the original equations. Let's use the second equation:

For x = 2: y = -(2)^2 + 2(2) + 4 y = -4 + 4 + 4 y = 4

For x = -1: y = -(-1)^2 + 2(-1) + 4 y = -1 - 2 + 4 y = 1

Therefore, the solutions to the system of equations are (x, y) = (2, 4) and (x, y) = (-1, 1).
