Need help with 2c and 2d please show all work

1. Solve the following constrained maximization and minimization problems. illustrating your answer with diagrams in each case: (a) max y = 2.x1 + 3x, subject to 2.1/ + 51} = 10 - Perfect Sug (b) max y = x x #.25 x2 75 subject to 2x; + 5.; = 10 - Coby Dous (c) min y = 2x, + 412 subject to .r9.25 0.75 (d) max y = (x1 + 2)(x2 + 1) subject to x1 + 12 = 21 2. (a) max y = 2x1 + 4x2 - x - 0.5.x; - 2xx, subject to 2x, + . = 10 (b) maxy = xx2 subject to xi + x; = 16 V(c) maxy = x; + .; subject to (x; /25) + (.x4/9) = 1 (d) min y = 2x1 + x2 subject to (0.2r, " + 0.8.r,") -2 = 1
