MAT1503 - ASSIGNMENT 03 SOLUTIONS (SEMESTER 01 -2022) (a) (i) We shall do this by substitution. Thus 2 (t + 2) + 4 (−2t − 1) + 6t = 2t + 4 − 8t − 4 + 6t = 0 Also 4 (t + 2) + 5 (−2t − 1) + 6t = 4t + 8 − 10t − 5 + 6t = 3 and finally 7 (t + 2) + 8 (−2t − 1) + 9t = 7t + 14 − 16t − 8 + 9t = 6 Thus, x = t+2, y = −2−1, z = t satisfy all three equation. This solution is general since it has the parameter t, enabling the generation of any other solution from this...

This solution is general since it has the parameter t, enabling the generation of any other solution from this solution. NB. Only questions 1 and 3 will be marked. ...

QUESTION 1.1

Question 1 (5) Write an overloaded function max that takes either two or three parameters of type double and returns the largest of them. Test your overloaded function in a program with the appropriate function calls and displays on the screen to demonstrate that the overloaded function works. Question 2 (5) Write a C++ program that includes a function to calculate the discount applicable on the price of an item. Your function should have three arguments: the price as a reference paramet...
