7. Use Gauss-Jordan elimination to solve the following linear system. X- 2z = 9 6x - 2y-5z 29 -5x + 5y + 3z = -14 O A. (-5,-3,0) О В. (3,2,-3) O C. (5,3,-5) O D. (3,6,-4) O Mark for review (Will be highlighted on the review page) « Prevlous Question Next Question >>

[Linear programming] I've already finished part (a), which is using Dijkstra algorithm. However in part (b), the cost of path has negative number. Could u please use label correcting algorithm to deal with it? and please tell me the difference between Dijkstra and label correcting, thanks :)

A vertical photograph taken from a camera has calibrated focal length f153.206 mm contains an image point "a" of object point A at coordinates x=64.969 mm. y =-78.526 mm relative to the fiducial axes, Calibration sheet shoWS x = 0.247 mm and y= 0.238 mm as calibrated coordinates of principal point. Also, lists the radial lens distortion coefficients K1 2.99778547 x10-08 mm-2 K2-3.15091119 x10A-12 mm-4: K3 H 6.05776623 x10-17 mm-6. Compute the corrected coordinates for the image point "a"
