For the following linear system, find the values of x1 and x2 that satisfy this system using the LU factorization technique. Please show all your work in details. Failing to show your work in details might lead you to zero. 4x1 - 8x2 = 40 , -x1 + 6x2 = 50
1. Consider the utility function: u(x1,x2) = x1 +x2. Find the corresponding Hicksian demand function 2. For each of the three utility functions below, find the substitution effect, the income effect, and the total effect that result when prices change from p = (2,1) to p' = (2,4). Assume the consumer has income I = 20. (a) Before doing any calculation, make an educated guess about the relative magnitude of the three substitution effects and the three income effects to be found below. (b)...
