The correct answer from the choices given will be -13 - 4i. The numerical part is the real number while the term containing i is the imaginary part.

<h3>What is the complex number?</h3>

A complex number is one that both a real and an imaginary component, both of which are preceded by the letter I which stands for the square root of -1.

The given complex number as;

\rm 13 + 4 i + n =0

By transfeering the left-hand side term to the right-hand side the sign will change. We will get the value of n as;

\rm n=-13 - 4i

Hence the correct answer from the choices given will be -13 - 4i.

Answer:

Step-by-step explanation:

Standard form of a circle is given by,

(x - a)² + (y - b)² = r²

Here, (a, b) is the center and 'r' is the radius of the circle.

For a circle having center (8, -4) and radius r = 1

Equation of the circle will be,

(x - 8)² + (y + 4)² = 1²

(x - 8)² + (y + 4)² = 1

Option (1) is the answer.

Question (2)

Circle with the center (-1, 0) and a point (2, -4) on it,

Radius of the circle = Distance between the center and the given point on                                         circumference

                                = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}

                                = \sqrt{(-1-2)^2+(0+4)^2}

                                = \sqrt{9+16}

                                = 5

Therefore, equation of the circle will be,

(x + 1)² + (y - 0)² = 5²

(x + 1)² + y² = 25

X - - 3 = 10 <br><br> What is the value of x?
Pepsi [2]

Answer:

x = 7

Step-by-step explanation:

Rule: an even number of - signs written one after another produces a plus number.

So - - 3 = 3

The rule also lets you do something strange like

- - - - 4 = 4 but you hardly ever see this.

Rule: an odd number of minus signs produces a minus number.

x + 3 = 10                 Subtract 3 from both sides.

x + 3 - 3 = 10 - 3      

x = 7
