real number can be a complex number but a complex number can not be a real number, verified.
the lengths of the complex number and its conjugate are equal but the converse is not necessarily true., verified.
Not all complex numbers are real numbers, despite the fact that every complex number is a real number.
In fact, determining whether the complex number z = a + bi is real is one of the complex conjugate's most useful applications. If and only if z = a + 0i, a complex number is real. In other words, a complex number is real if it contains an imaginary part.
Mathematical proof:
Let z = a+bi, where a and b = real numbers.
Let z* =complex conjugate of z.
Then the magnitude (absolute value) of z is:
|z| = √(a²+b²).
And the value of z* is:
|z*| = √[a²+(-b)²] = √(a²+b²).
So |z| = |z*|.
This Completes the Proof.

using ordinary interest, calculate the missing information for the following simple discount
Face Value $50,000. Discount Rate (%) 13. Date of Note Apr. 5. Term (days) — Maturity Date, Aug. 14. Bank Discount — Proceeds —
The Bank discount and proceeds of the given information is:
$2365.27 and $47634.73 respectively.
Given the face value is $50,000
Discount rate = 13%
No.of term days = April 5 to August 14
= 131 days.
Bank discount = ?
Proceeds = ?
First calculate the bank discount using the formula:
Bank discount = face value × discount rate × time
Bank discount = $50,000 × 0.13 × 131/360
= 50,000×0.13×0.36388
= $2365.27
now calculate the proceeds using the formula :
Proceeds = face value - bank discount
= 50,000 - 2365.27
= $47634.73
Hence the bank discount and proceeds are $2365.27 and $47634.73 respectively.

Here is a linear equation: y = 2/3x + 1 Are (6, 5) and (9, 8) solutions to the equation? Explain or show your reasoning.
A linear equation is a mathematical form of a line segment the point (6,5) satisfies the equation y = 2/3x + 1 so it is the solution of the equation but (9,8) is not the solution.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
As per the given linear equation, y = 2/3x + 1
To be a point of its solution the point must satisfy the given equation.
Substitute (6,5)
5 = (2/3)6 + 1
5 = 2(2) + 1 = 5
Therefore, the (6,5) is the solution of the equation.
Substitute,(9,8)
(2/3)9 + 1 = 7
8 ≠ 7
So,(9,8) is not the solution of the equation.
Hence "A linear equation is a mathematical form of a line segment the point (6,5) satisfies the equation y = 2/3x + 1 so it is the solution of the equation but (9,8) is not the solution".

You want two integers that have a sum of 2 and a product of -15.
Factor pairsSolving a problem like this can often be done fairly quickly by listing the factor pairs that make up the product. Only the pairs need be listed that have a sum with the same sign as the sum you're looking for.
Divisors of 15 are 1, 3, 5, and 15. You want a negative product with the largest factor being positive:
-15 = 15(-1) = 5(-3)
The sums of these factor pairs are 14 and 2. The latter pair is the one of interest.
The two integers are 5 and -3.

Additional comment
The desired relations can be expressed as a quadratic equation. It generally works well to solve it by completing the square.
If one of the numbers is x, the other is 2-x. Their product is -15:
x(2 -x) = -15
2x -x^2 = -15 . . . . . eliminate parentheses
x^2 -2x = 15 . . . . . . make the leading coefficient positive

The equation that could model the given situation is y = -x + 30.25. The correct option is B. y = -x + 30.25
Perimeter of a rectangle and equationsFrom the question, we are to determine the equation that could model the given situation
The perimeter, P, of a rectangle is given by the formula,
P = 2(l + w)
Where P is the perimeter
l is the length
and w is the width
From the given information,
The perimeter of a rectangular room is 60.5 feet.
∴ P = 60.5 feet
Also,
x is the width of the room and y is the length of the room
That is,
l = y
and
w = x
Thus,
The equation becomes
60.5 = 2(y + x)
2(y + x) = 60.5
Divide through by 2
y + x = 30.25
y = -x + 30.25
