For no solution, the two lines have to never intersect, which means they have to be parallel lines. In other words, no solution will satisfy both equation. For infinitely many solutions, the two lines have to overlap each other, which means one equation has to be a multiple of the other equations.
[joint] the site of the junction or union of two or more bones of the body; its primary function is to provide motion and flexibility to the frame of the body. Some are immovable, such as the sutures where segments of bone are fused together in the skull.
The skull is the part of the skeleton that covers and protects the brain and other sense organs. The human skull is composed of 22 types of bones. These bones are separated into two categories, the bones the form the cranium and facial bones.The section of the brain that holds the brain is known as the cranium.The cranium is made up of eight flat bones that are connected. The cranium bones form the forehead and eye socket and the back of the skull.The facial bones include fourteen bones, the majority of them symmetrical to give the face symmetry. The facial bones include bones such as the maxilla, which is the upper jaw and the nasal bone.he cranium bones form the forehead and eye socket and the back of the skull.
