What is the solution to the system of equations? (–2, –8) (–1, –5) (0, –2) (2, 4)

Which of the following equations is of the parabola whose vertex is at (2, 3), axis of symmetry parallel to the y-axis and p = 4? a.)y-3 = 1/16 (x-2)^2 b.)y+3 = -1/16 (x+2)^2 c.)x-2 = 1/16 (y-3)^2

Explain why the factor 1.5 is broke. into two numbers in the model.
