Answer:
Slope = -3/2 or -1.5
Step-by-step explanation:
The Formula for slope is (The picture linked)
So,
Which is equal to... when simplified
Which is equal to or -1.5 which is the slope
Solve the equation simultaneously. Y=x² + 2x + 1, Y= x²+2x - 2.. Solve for the values of X and Y.
1 answer:
The two functions should never intersect.
Since y = y, we can equate the other side of both equations together.
x^2 + 2x + 1 = x^2 + 2x - 2
Rearrange the equation to bring all the terms to one side.
0 = x^2 - x^2 + 2x - 2x - 2 - 1
0 = -3
You can see that does not make sense, so we can conclude that there are no points of intersection between the two functions.
I also graphed the functions. In the first pic you can see that the red is between the blue and they don't intersect. In the second pic I zoomed in so you can see the right side of the graph going up to y = 600 and the red is still between the blue.
