Given below is an equation of a parabola. What are the coordinates of the vertex? y = (x + 2)^2

a (–2, 0)
b (2, –2)
c (–2, 2)
d (2, 0)

Find the length of the following tangent segments to the circles centered at o and o' whose radii are 5 and 3 respectively and the distance between o and o' is 12. what is the tangent segment of cd?

The general form of the quetion of a circle is ax^2+by^2+cx+dy+e=0 where a=b=0 if the circle has a radius of three units and the center lies on the y axis which set of values of a, b, c, d, and e might correspond to the circle

Select a graph that have an equation with a < 0
