If Bold v 1 comma ... comma Bold v Subscript pv1,...,vp are in a vector space V, then Span StartSet Bold v 1 comma ... comma Bold v Subscript p EndSetSpanv1,...,vp is a subspace of V. B. The column space of an mtimes×n matrix A is a subspace of set of real numbers R Superscript mℝm. C. The null space of an mtimes×n matrix is a subspace of set of real numbers R Superscript nℝn. Equivalently, the set of all solutions to a system Axequals=0 of m homogeneous linear equations in n unknowns is a subspace of set of real numbers R Superscript nℝn. D. An indexed set StartSet Bold v 1 comma ... comma Bold v Subscript p EndSetv1,...,vp of two or more vectors in a vector space V, with Bold v 1v1not equals≠0 is a subspace of V if and only if some Bold v Subscript jvj is in Span StartSet Bold v 1 comma ... comma Bold v Subscript j minus 1 Baseline comma Bold v Subscript j EndSetSpanv1,...,vj−1,vj.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
