The vertex form of the equation of a parabola is y = 2(x + 3)2 - 5. what is the standard form of the equation?

a) y=2x^2+12x+13

b) y=2x^2+5x+9

c) y=4x^2+4x+4

d) y=2y^2+5y+9

Solve the system by the elimination method. 3x - 2y - 7 = 0 5x + y - 3 = 0 to eliminate y, the lcm is 2. which of the following is the resulting equations? 1.3x - 2y - 7 = 0 5x + y - 3 = 0 2.3x - 2y - 7 = 0 -10x - 2y + 6 = 0 3.3x - 2y - 7 = 0 10x + 2y - 6 = 0

Aperpendicular bisector, cd is drawn through point con ab if the coordinates of point a are (-3, 2) and the coordinates of point b are (7,6), the x-intercept of cd is point lies on cd.
