The standard form or the equation of a parabola is y = 7x^2 + 14 +4. What is the vertex form of the equation? Can someone please explain how to get the answer. I am having a difficult time understanding the concept. Answers choices: y = 7(x + 2)^2 - 3 y = 7(x + 2)^2 + 3 y = 7(x + 1)^2 - 3 y = 7(x + 1)^2 + 3

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part 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 (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)
