Unit 1 Lesson 9 : The Big M Method Learning outcomes • The Big M Method to solve a linear programming problem. In the previous discussions of the Simplex algorithm I have seen that the method must start with a basic feasible solution. In my examples so far‚ I have looked at problems that‚ when put into standard LP form‚ conveniently have an all slack starting solution. An all slack solution is only a possibility when all of the constraints in the problem have or = constraints‚ a starting basic

7a – 6b John says the answer is 2a + 2b and Sarah says the answer is 10a + 14b. What is the correct answer? Sarah 2. Simplify these expressions. a) 4d + 6e – 2d – 3e = 2d-3e b) 12g – 3h – 8g + h = 4g-4h c) k + 2k + 3k – m – 2m – 3m = 6k-3m d) 7c + 4d – 10c + 5d = -3c+9d 3. Multiply out these brackets. a) 3(2a + 7) = 6a+21 b) 5(3x – 2y) = 15x-10 c) 2(4g2 – 3g) = 8g2-6 4. Expand the brackets and then simplify the expression. a) 2(x + 8) + 3(x + 1) = 2x+16+3x+3

Science exhibition Exhibitors are responsible for designing their exhibition stand. The exhibit should be engaging for a non-scientific visitor and include associated interactive activities. Most exhibits are a standard size of 3m x 3m‚ or 4m x 2m. The Society can advise and help with basic equipment hire (poster boards‚ tables and chairs). Representatives of each exhibit should attend the Planning Day at the Society in late January. At this event the Society provides guidance on designing exhibits
