Write C++ expressions for the following algebraic expressions:
y=6x
a=2b+4c
y=x3
g=x+2/z2
y=x2/z2
In C++
(Algebra: solve 2 × 2 linear equations)
You can use Cramer’s rule to solve the following 2 × 2 system of linear equation:
ax + by = ecx + dy = fx = (ed - bf) / (ad - bc)y = (af - ec) / (ad - bc)
Write a program that prompts the user to enter a, b, c, d, e and f and displays the result.
If ad - bc is 0, report that “The equation has no solution”.
Sample Run 1
Enter a, b, c, d, e, f: 9.0 4.0 3.0 -5.0 -6.0 -21.0
x is -2 and y is 3
Sample Run 2
Enter a, b, c, d, e, f: 1.0 2.0 2.0 4.0 4.0 5.0
The equation has no solution
C++ CODE ONLY:
Write a program that takes as input five numbers and outputs the mean (average) and
standard deviation of the numbers. If the numbers are X₁, X2, X3, X4, and x5, then the mean is
X = (X1 + X2 + X3 + x4 + x5 ) / 5 and the standard deviation is:
(x₁−x)²+ (x₂-x)²+ (x¸¯x)²+(x¸−x)²+(x¸¯x)²
S =
5
Your program must contain at least the following functions:
1. a function that calculates and returns the mean; and,
2. a function that calculates the print standard deviation.
Input
1.5 integers
Output
Enter five numbers: 2 3 9 10 11
The mean is 7.00.
The standard deviation is 3.742.
Enter five numbers: 7 7 8 9 11
The mean is 8.40.
The standard deviation is 1.497.

At the end of 10 years you would like to have $10,000 in the account. How much do you need to deposit today to make that happen? You can use the following formula: P =F/(1 + r)n The terms in the formula are as follows:• P is the present value, or the amount that you need to deposit today.• F is the future value that you want in the account. (In this case, F is $10,000.)• r is the annual interest rate.• n is the number of years that you plan to let the money sit in the account. Write a method named PresentValue that performs this calculation. The method should accept the future value, annual interest rate, and number of years as arguments. It should return the present value, which is the amount that you need to deposit today. Demonstrate the method in an application that lets the user experiment with different values for…arrow_forward
