Find the 3x3 matrix a corresponding to orthogonal projection onto the solution space of the system below. 2x + 3y + z = 0; x-3y-z = 0. your solution should contain the following information: (a) the eigenvector(s) of a that is (are) contained in the solution space; (b) the eigenvector(s) of a that is (are) perpendicular to the solution space; (c) the corresponding eigenvalues for those eigenvectors.

Someone answer asap for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
