(Algebra: solve 2 X 2 linear equations) You can use Cramer's rule to solve the
following 2 X 2 system of linear equation:
ax + by = e
cx + dy = f
●
x =
ed - bf
bc
ad
y =
af - ec
ad
bc
-
Write a program that prompts the user to enter a, b, c, d, e, and f and display the
result. If ad- bc is 0, report that The equation has no solution.
Enter a, b, c, d, e, f: 9.0, 4.0, 3.0, -5.0, -6.0, -21.0 Enter
x is -2.0 and y is 3.0
Enter a, b, c, d, e, f: 1.0, 2.0, 2.0, 4.0, 4.0, 5.0 Enter
The equation has no solution
(Financial: credit card number validation) Credit card numbers follow certain pat-
terns. A credit card number must have between 13 and 16 digits. It must start with:
4 for Visa cards
5 for Master cards
37 for American Express cards
6 for Discover cards
In 1954, Hans Luhn of IBM proposed an algorithm for validating credit card
numbers. The algorithm is useful to determine whether a card number is entered
correctly or whether a credit card is scanned correctly by a scanner. Credit card
numbers are generated following this validity check, commonly known as the
Luhn check or the Mod 10 check, which can be described as follows (for illustra-
tion, consider the card number 4388576018402626):
1. Double every second digit from right to left. If doubling of a digit results in a
two-digit number, add up the two digits to get a single-digit number.
4388576018402626
→ 2 * 2 = 4
→ 2 * 2 = 4
→ 4 * 2 = 8
→ 1 * 2 = 2
6 * 2 = 12 (1+ 2 = 3)
→ 5 * 2 = 10 (1+ 0 = 1)
→ 8 * 2 = 16 (1 + 6 = 7)
→ 4 * 2 = 8
[Calculate grades’ average for a student] write a program that calculates the student grades’ average for a semester for the number of courses taken in that semester. Your program should do the following:
1.Read from user the number of courses (n)
2. Then, read the courses’ grades for n times (Hint: use a loop)
3.If a grade is grater than 100 or less than 0, ask the user to enter the grade again.
4.Calculate the average of grades using the following formula:
average = (sum of grades) / n
5.Print out the average grade on the screen.
Note: Always use appropriate data types.
