Provide an appropriate response.Suppose that you are solving a system of three linear equations and have evaluated D, Dx, Dy, and Dz. Under what condition does Cramer's rule not apply?
A. Dx = 0 B. D = 0; and either Dx = 0, Dy = 0, or Dz = 0 C. Dx = 0, Dy = 0, or Dz = 0 D. D = 0
Solve the equation in part (a) graphically, expressing the solution to the nearest hundredth. Then, use the graph to solve the associated inequalities in parts (b) and (c), expressing endpoints to the nearest hundredth.(a) 
= 0; (b) 
> 0; (c) 
< 0
A. (a) {0.34} (b) (0.34, ?) (c) (-?, 0.34) B. (a) {1} (b) (1, ?) (c) (-?, 1) C. (a) {0.84} (b) (0.84, ?) (c) (-?, 0.84) D. (a) {0.20} (b) (0.20, ?) (c) (-?, 0.20)
