Answer:
In naming a ray, we always begin with the letter of the endpoint (where the ray starts) followed by another point on the ray in the direction it travels. Since the vertex of the angle is the endpoint of each ray and our vertex is , each of our rays must begin with . Only fails to do so.
The graph of the given Quadratic equation is attached in the Answer, where we can se that the axis of symmetry is :
Simply the answer is -x^2-x+6 but not sure if you want to factor it but it would be (x-2)(x+3) and not sure how to do the domain
You just multiply 7 x 20 and you will get the answer of 140 then just add two zeroes to get 14000.
