- (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 ed – bf af- ec ad - bc cx + dy = f ad – bc y = Write a program that prompts the user to enter a and f and display the result. If ad - bc is 0 b, c, d , e, , report that The equation has no solution.arrow_forward( don't hand writing solution)arrow_forwardSimplify the following expression as much as possible ? *arrow_forward
- Write true if the two statements are equivalent; otherwise write false. (p∨∼q) ∨q and parrow_forward(Apartment problem) A real estate office handles , say, 50 apartment units. When the rent is, say, $600 per month, all the units are occupied. However, for each, say $40 increase in rent, one unit becomes vacant. Moreover, each occupied unit requires an average of $27 per month for maintenance. How many units should be rented to maximize the profit? Write a program that prompts the user to enter: The total number of units. The rent to occupy all the units. The increase in rent that results in a vacant unit. Amount to maintain rented unit. The program then outputs the number of units to be rented to maximize the profit.arrow_forward6.

- (Using Python)Write program to ask user to enter number and assign to variable points. Write an if-else statement that determines whether the points variable is outside the range of 17 to 81. If the variable’s value is outside this range it should display “Invalid points”, otherwise ,It should display “Valid points”arrow_forward(C PROGRAMMING ONLY) 6. Deal or No Deal?by CodeChum Admin When I was a kid, I used to watch this TV game show, Deal or No Deal? In the game, there are different brief cases, each labeled with a number. Inside each brief case is an amount in Pesos and the goal is to guess which briefcase contains the smallest amount. In this program, instead of just finding the smallest amount, your task is to ask the user for an integer input and print the values in the array smaller than the inputted integer. Instructions: In the code editor, you are provided with an array with 100 elements.Your task is to ask the user for an integer input and then print all the elements in the array whose value is lesser than the inputted integer.Input 1. Inputted integer Output Enter value: 6132450351503022244arrow_forward(25-26) Verify that each of the following statements is a false statement by finding a counterexample. For all numbers x: |x| >0 For all numbers x: x > xarrow_forward
