I need of questions 6->10 urgent

Given k = 5; m = 3; p = 5 for the following LTI system; k, m, and p will be needed for the following questions Q1 and 22: y(n ) + y(n - k) = x(n ) x(n - m) + 2x(n - p) - 3x(n - 6) Determine the transfer function of the system in the Z domain. Is the system stable? Why? 1. 2. 3. Determine the direct form Il realization of the system. 4. Determine the impulse response of the system. 5. Determine the output yan ) from the system for an input x(n ) = {1, k, 1, m, 1, 1, 1, k, m, p}; assumex and y equal to zero for n
