Find all solutions of the equation ax = b with. 4 and express them in parametric vector form. Find the inverse of the matrix b = . Problem 3. (3+2=5 points) (a) find the point on the plane w spanned by . , that is closest to the point y = . 1 (b) find the distance of y from w . Find the least-squares solution to the inconsistent system of equations ax = b, where. Imagine you want to choose a three course meal in a restaurant and you want to spend exactly 60$ in total. You plan to dedicate 25% of the total meal price (appetizer, main course and dessert) to the tax and gratuity. In addition, you want to choose a dessert and an appetizer which in total cost twice as much as your main course. Assume that the menu can provide you with options at any price for each course.
