(Algebra: solve 2 X 2 linear equations) You can use Cramer's rule to solve thefollowing 2 x 2 system of linear equations:ed – bfaf – ecybcax + by = eX =cx + dy = fadad – bcWrite a function with the following header:void solveEquation(double a, double b, double c, double d,double e, double f, double& x, double& y, bool& isSolvable)If ad – bc is 0, the equation has no solution and isSolvable should be false.Write a program that prompts the user to enter a, b, c, d, e, and f and displays theresult. If ad – bc is 0, report that "The equation has no solution." See Program-ming Exercise 3.3 for sample runs.

Also test the function.
Objective: Practice writing recursive functions in python3 Make the five recursive functions described below in python3 by using the starter code recursive_functions.py. For each function, figure out how to solve it conceptually : write down the base case (when recursion stops) and how each recursive function-call moves towards the base case. The functions should not print anything (except you may add temporary print statements to help debug them). You can test your program by using the provided program test_recursive_functions.py. Don't edit the test program. Put it into the same directory (folder) with your recursive_functions.py and run it. It will import your functions as a module, test your functions, and tell you when each function is returning correct results. 1. Factorial In math, if you have a number n, the factorial function (written n!) computes n x (n-1) x (n-2) x (n-3) x ... x 1. For example: 0! is defined to be 1 1! = 1 2! = 2 x 1=2 3! = 3 x 2 x 1=6 4! = 4 x 3…
Q11/ Write a program in c++ that converts .kilometers per hour to miles per hour Hint: miles (kilometers-0.6213712) .By using functions
(Perfect Numbers) An integer number is said to be a perfect number if its factors, including1 (but not the number itself), sum to the number. For example, 6 is a perfect number because 6 =1 + 2 + 3. Write a function isPerfect that determines whether parameter number is a perfect number. Use this function in a program that determines and prints all the perfect numbers between 1and 1000. Print the factors of each perfect number to confirm that the number is indeed perfect.Challenge the power of your computer by testing numbers much larger than 1000.
One mile is 1.6 kilometers (for purposes of this question). Define a function miles_to_kilometers that consumes a distance in miles (a number) and returns the distance in kilometers (a float). No docstring required.(use Python) For example: Test Result print(miles_to_kilometers(1.0)) 1.6 Use these statements to test your miles_to_kilometers function: assert_equal(miles_to_kilometers(10),16.0) assert_equal(miles_to_kilometers(15),24.0) assert_equal(miles_to_kilometers(35),56.0)
Q11 Write a C++ program to estimate the student's grade of 7 Courses, by following the conditions below: (Using functions under conditions 2, 3 and 4) 1. You must find the grade for at least one student. 2. Check if the student's success in all courses and any degree over 100 is not acceptable. 3. Calculate the cumulative Grade Point A verage. 4. Estimate the grade according to: AA: 100-90, BA: 89-80, BB: 79-70, CB: 69-60, CC: 59-50.
Q9/Write a program in c++ that inputs a three-digit integer, separates the integer into its individual digits and prints the digits separated from one another by three spaces each by using functions. For example, if the user types in 429, the program should print: 4 2 9
Need some help writing functions for this problem. Write a pair of functions cube which return the cube of their arguments.
Create a function that returns the simplified version of a fraction. Examples simplify ("4/6") simplify("10/11") "10/11" simplify("100/400") "1/4" simplify("8/4") → "2" → "2/3" Notes • A fraction is simplified if there are no common factors (except 1) between the numerator and the denominator. For example, 4/6 is not simplified, since 4 and 6 both share 2 as a factor. • If improper fractions can be transformed into integers, do so in your code (see example #4).
