I need to find the vertex for 3x^2 + 2x - 1

Atoy company is considering a cube or sphere-shaped container for packaging a new product. the height of the cube would equal the diameter of the sphere . compare the volume to surface area ratios of the containers. which packaging will be more efficient? for a sphere, sa =4πr²

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5

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