For the given quadratic equation convert into vertex form, find the vertex and find the value for x=6 y=-2x^2+2x+2

If sr is 4.5cm and tr is 3cm, what is the measure in degrees of angle s?

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y > 2x + 3y is less than negative 3 over 2 times x minus 4part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points)part b: is the point (â’4, 6) included in the solution area for the system? justify your answer mathematically. (4 points)
