Identify the focus and directix of graph of the equation y = -2x^2 the vertex is located at the origin

Astudent survey asked: "how tall are you (in inches)? " here's the data: 67, 72, 73, 60, 65, 86, 72, 69, 74 give the five number summary. a. median: 73, mean: 70.89, iqr: 5, min: 60, max: 74 b. 60, 66, 72, 73.5, 86 c. 60, 67, 72, 73, 74 d. 0, 60, 70, 89, 74, 100

Which shows the graph of the solution set of 3y – 2x > –18?

Find the solution(s) to the system of equations. select all that apply y=x^2-1 y=2x-2
