1. Problem Description

The problem asks us to find the intersection points of two parabolas, given by the equations y=5xx2y = 5x - x^2 and y=x2x+4y = x^2 - x + 4. We need to solve for xx and yy where the two equations are equal.

2. Solution Steps

First, we set the two equations equal to each other:
5xx2=x2x+45x - x^2 = x^2 - x + 4
Next, we rearrange the equation to get a quadratic equation equal to zero:
0=x2x+45x+x20 = x^2 - x + 4 - 5x + x^2
0=2x26x+40 = 2x^2 - 6x + 4
We can simplify the equation by dividing by 2:
x23x+2=0x^2 - 3x + 2 = 0
Now we factor the quadratic equation:
(x1)(x2)=0(x - 1)(x - 2) = 0
This gives us two possible values for xx:
x=1x = 1 or x=2x = 2
Now we substitute these values of xx into either of the original equations to find the corresponding yy values. Let's use y=5xx2y = 5x - x^2:
If x=1x = 1, then y=5(1)(1)2=51=4y = 5(1) - (1)^2 = 5 - 1 = 4.
If x=2x = 2, then y=5(2)(2)2=104=6y = 5(2) - (2)^2 = 10 - 4 = 6.
So the intersection points are (1,4)(1, 4) and (2,6)(2, 6).

3. Final Answer

The intersection points are (1,4)(1, 4) and (2,6)(2, 6).
