please help me with the questions highlighted. only help if you know the answer 100% and please show work

Start Typing in MATLAB Use MATLAB: 1.) Determine if the vectors v- (2,-1,2,3), v2 (1,2,5,-1), v3 (7,-1,5, 8) are linearly independent vectors in R4. Type: L1-2 -1 2 3;1 2 5 -1;7 -1 5 8 LR1 rref(L1) If you decide that vi, V2, vs are linearly independent type: ANSL11 Otherwise type: ANSL1 0 2.) Determine if the vectors v (2,-1,0,3), v2 (1,2,5, -1), V3(7,-1,5, 8) are linearly independent vectors in R4 Type: L2- 2 -10 3;1 2 5-1;7 -1 5 8 LR2 rref(L2) If you decide that vi, V2, Vs are linearly independent type: ANSL2 1 Otherwise type: ANSL2 0 3.) If the vectors in problem 2 above are linearly dependent, write v1 as linear combi- nation of two other vectors. Type: L3- 2 -1 0 3;1 2 5-1;7 -1 5 8] LR3 rref(L3) Solve L3 X = 0 to get cluutc2u2+CgU3 = 0 then solve it for UI. (need pen and paper !!!! ) Your answer should look like v1 av2 + bs If you calculated a and b, type: ANSa-[a] Enter the numerical value of a inside the bracket for a type: ANSb- bEnter the numerical value of b inside the bracket for b Start Typing in MATLAB Use MATLAB: 1.)
