(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

CPU Usage
We have the hourly average CPU usage for a worker's computer over the course of a week. Each row of data represents a day of the week starting with Monday. Each column of data is an hour in the day starting with 0 being midnight.
Create a chart that shows the CPU usage over the week. You should be able to answer the following questions using the chart:
When does the worker typically take lunch?
Did the worker do work on the weekend?
On which weekday did the worker start working on their computer at the latest hour?

A programmer can help you find your car in the parking by only giving him the brand of your car. The program will give you the number of the parking lots that have cars with the same brand as yours. The program works as follows: Input from the user car_brand Loop over the cars in parking_cars list (hint: use enumerate) Save the indices in a list parking_lots of the cars with the same brand as the user's (car_brand) If parking_lots has values, print "Your car might be in any of these parking lots <parking_lots>".

Use this function in a program that determines and prints all the perfect numbers between 1 and 1000. Print the factors of each perfect number to confirm that the number is indeed perfect.

If the guessed number is not correct, the program outputs a message indicating whether the guess is low or high. Modify the program as follows: Suppose that the variables num and guess are as declared in Example 5-6 and diff is an int variable. Let diff = the absolute value of (num - guess). If diff is 0, then guess is correct and the program outputs a message indicating that the user guessed the correct number. Suppose diff is not 0. Then the program outputs the message as follows: If diff is greater than or equal to 50, the program outputs the message indicating that the guess is very high (if guess is greater than num) or very low (if guess is less than num). If diff is greater than or equal to 30 and less than 50, the program outputs the message indicating that the guess is high (if guess is greater than num) or low (if guess is less than num).
