The hip fusion is better tolerated by male than by female patients. The results depend on the position in which the hip has been fused. Too much of a bent position in the thigh and the adducted thigh (thigh drawn to the midline) can result in pain in the spine.
The three types of solution sets: A system of linear equations can have no solution, a unique solution or infinitely many solutions. A system has no solution if the equations are inconsistent, they are contradictory. for example 2x+3y=10, 2x+3y=12 has no solution. is the rref form of the matrix for this system.
If the graphs of the equations are parallel, then the system of equations will have no solution. Because parallel lines never intersect each other. If the system has at least one solution (one solution or infinitely many solutions), then it is said to be consistent system.
