Any complex number can be divided into four categories based on the characteristics of the real component and imaginary part:

Complex numbers are those that are expressed as a+ib, where a and b are actual numbers and I is a fictitious number called a "iota." I has the value (-1). As an illustration, the complex number 2+3i is made up of the real number 2 (Re) and the imaginary number 3i (Im).

The real and imaginary halves of a complex number are represented by the first and second values, respectively, of the complex data type in Python.

Answer:

x = 2

y = 5

Step-by-step explanation:

Brainly doesn't provide online graphing tools, so I will try to walk you through what to do.

First put both equations in slope-intercept form:

y + x = 7  →  y = -x + 7

3y - 6x = 3   →   3y = 6x + 3  →  y = 2x + 1

These are easy to graph now.  

For equation (1), place a point on the y-intercept (0,7), then draw a line with a slope of -1  (down one, over one, down one, over one, etc.).  The x-intercept is (7,0).

For equation (2), the y-intercept is point (0,1).  Draw a line with a slope of 2 (up 2, over 1, up 2, over 1, etc.)  The x-intercept is (-1/2, 0).

Where the 2 lines intersect is the solution.  They should intersect at point (2,5).

Answer: The smallest critical value is -5

Step-by-step explanation:

Critical values occur at critical points(they give you important information).

In all rational functions, x-intercepts(zeros) and discontinuities need to be considered. So the critical values here are -5, -3, and -2.

A polynomial equation is an equation that consists two or more algebraic terms including at least one variable and constants through the algebraic operation ( addition, substraction, and multiplication).

A polynomial is defined as an equation that has at least one algebraic term with at least one variable and all exponents are integers greater than or equal to 0. The polynomial equation is expressed in the form of aₙ(x), here a is the coefficient, x is the variable and n is the exponent and expanded form is ; F(x) = aₙxₙ + aₙ₋₁ xₙ₋₁ + …….. + a₁x +a₀ = 0

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the distance between Manchester and Newton be = 10.94 miles

Let the distance between Newton and Fairfax be = 13.57 miles

Let the distance between Fairfax and Hillsboro be = 8.57 miles

Now , the distance between Manchester and Fairfax = distance between Manchester and Newton + distance between Newton and Fairfax

Substituting the values in the equation , we get

The distance between Manchester and Fairfax = 10.94 + 13.57

The distance between Manchester and Fairfax = 24.51 miles

So , the difference between the distances A = distance between Manchester and Fairfax - distance between Fairfax and Hillsboro

Substituting the values in the equation , we get

The principal of interest 3415 naira, rate = 5% and time 4 yrs and 3 months​ is 4017.64 naira.

In the context of borrowing, principal refers to the initial sum of a loan; it can also refer to the balance still owed on a loan. For instance, the principal of a $50,000 mortgage is $50,000. If you pay off $30,000, the remaining $20,000 constitutes the principal balance.

The principal of a loan determines how much interest you will pay. When you pay a loan off each month, the amount first goes to pay off the interest that has accumulated; only then is the remaining amount applied to the principal. The only way to lower the monthly interest payment is to reduce the loan's principal.

Answer:no

Step-by-step explanation:

Let's start with the first method: converting the fractions to the same denominator. First, we'll set up 5/8 and 1/2 side by side so they are easier to see:

Converting Denominator

5

8

&

1

2

Our denominators are 8 and 2. What we need to do is find the lowest common denominator of the two numbers. This is the smallest number that can be divided by both 8 and 2. In this case, the lowest common denominator is 8.

If we multiply the first denominator (8) by 1 we will get 8. If we multiply the second denominator (2) by 4 we will also get 8. We also need to multiply the numerators above the line by the same amounts so that the fraction values are correct:

5 x 1

8 x 1

1 x 4

2 x 4

This is what 5/8 and 1/2 look like with the same denominator:

5

8

&

8

Now that these fractions have been converted to have the same denominator, we can clearly see by looking at the numerators that 5 is NOT less than 4 which also means that 5/8 is NOT less than 1/2.

An equilateral triangle can be defined as a type of  triangle having all three sides of equal length.

It is also known as a regular triangle.

Unlike other triangles, an equilateral triangle is one having not only two sides equal like an isosceles triangle but all of its sides equal in length.

The formula for perimeter of an equilateral triangle is expressed as;

P = 3x

Where;

Substitute the values

12x + 33 = 3x

collect like terms

12x - 3x = 33

The factors or multiples of the algebraic expression, x² - 36 are (x-6) and (x+6) .

Factorization of algebraic expressions is defined as the process of finding the factors of an expression which refers to finding two or more expressions whose product is equals to that expression. Some Identities which are used to Factorize Algebraic Expressions,

(a+b)² = a² + b² + 2ab

(a - b)² = a² + b² - 2ab

a² - b² = (a+b)(a -b) etc.

We need to factorise, p(x) = x² − 36.

The algebraic expression, p(x) can be factorised by using property, a² - b² = (a+b)(a-b). So, it can be written as x² - 6², comparing it with a² - b² , here a = x,

b = 6. Hence, (x² − 36) = (x+6)(x−6). Therefore, the required factors are (x+6)(x−6).

The main symbol attached to any algebraic expression is  x. Each radical expression consists of three separate components: first the "square root" sign itself serves as the radical sign.

The component of the expression inside the radical is known as the radicand
