The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

A mathematical statement that has a "equal to" symbol between two expressions with equal values is called an equation. as in 3x + 5 Equals 15, for instance. Equations come in a variety of forms, including linear, quadratic, cubic, and others. In this tutorial, let's study more about math equations.

Answer: The solution of the equation is x = 48. The equation is 20 = x - 28.

Step-by-step explanation:

-20 is like having -20 dollars, and you want to know how much you have to add to it to get to 28 dollars. So we add 20 to -28 and we get the number x = 48, so 48 dollars is what we need to add to -20 dollars to get to 28 dollars.

Answer:

y = 2x + 2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, 6 ) and (x₂, y₂ ) = (9, 20 )

m = [tex]\frac{20-6}{9-2}[/tex] = [tex]\frac{14}{7}[/tex] = 2 , then

y = 2x + c ← is the partial equation of the line

to find c substitute either of the 2 points into the partial equation

using (2, 6 ), then

6 = 2(2) + c = 4 + c ( subtract 4 from both sides )

2 = c

y = 2x + 2 ← equation of line

Answer:

[tex]\boxed{y = 4x + 7}[/tex]

Step-by-step explanation:

The equation of a line in slope-intercept form is

y = mx + b

where m is the slope and b the y-intercept

To find the slope, take the two points, find the difference in y values and divide by the corresponding difference in x values

Two points are [tex](- 1, 3)[/tex] and [tex](- 2, -1)[/tex]

Difference in y values [tex]= -1 -3 = -4[/tex]

Difference in corresponding x values [tex]= -2 - (-1) = -2 + 1 = -1[/tex]

Slope

 [tex]m = \dfrac{-4}{-1} = 4[/tex]

So the equation of the line is of the form
[tex]y = 4x + b[/tex]

To find b, take the coordinates of any of the two points and plug the x and y values into the above equation and solve for b

Let's take point (-1, 3)

Plug in values:

[tex]3 = -4 + b\\\\3+4 = b\\ \\b = 7[/tex]

Therefore the equation of the line is

The multiplicative inverse of 6 + 2i is 3/20 - 1/20i.

When a number is multiplied by its original number, the multiplicative inverse of that number, or x-1, produces a value equal to 1. The multiplicative inverse of 2, for instance, is 2-1 since it fulfills the formula: 2 x 2-1 = 2 x 12 = 1. It is also known as a number's reciprocal.

Use the following method to determine a complex number's multiplicative inverse:

The original complex number is reciprocated to find the inverse. The complex number (6+2i) has a reciprocal of 1/6+2i. Simplify by multiplying the reciprocal's numerator and denominator by the conjugate of the denominator:

1/6+2i × 6 - 2i/6 - 2i

Answer:

Step-by-step explanation:

The general formula for finding the antiderivative of a polynomial function is to add one to the exponent of each term and divide by that new exponent.

To find the antiderivative of y = 5x -6x² +9x³, we need to integrate each term individually, using the general formula:

∫ (5x) dx = (5/1)x^(1+1) = 5x^2 + C

∫ (-6x²) dx = (-6/2)x^(2+1) = -3x^3 + C

∫ (9x³) dx = (9/4)x^(3+1) = (9/4)x^4 + C

So the antiderivative of y = 5x -6x² +9x³ is:

∫ y dx = 5x^2 - 3x^3 + (9/4)x^4 + C

Where C is the constant of integration, which can take any real value.

Answer: Two times a number y would be represented mathematically as 2*y. It means that a number y will be multiplied by 2 to get the result.

Using cosine law and sine law, the value of angle E and D are 14° and 35° and the length of side d is 19 units

The law of cosines is a mathematical formula used to calculate the measure of a third side of a triangle when two sides and the angle between them are known. It is also used to calculate the angles of a triangle when all three sides are known. The formula is: c² = a² + b² - 2ab cos(C).

In this given problem, triangle DEF can be;

f² = e² + d² - 2(e)(d) cos(F)

But we don't know the length of side d

Using sine law

f / sin F = e / sin E

25 / sin 131 = 8 / sin E

sin E = 8 * sin 131 / 25

E = 13.97°

E = 14°

Using sum of angles in a triangle

D + E + F = 180°

D = 180 - (14 + 131)

D = 180 - 145

D = 35°

Using cosine law;

d² = e² + f² - 2(e)(f)cos(D)

Substituting the values into the formula;

d² = 8² + 25² - 2(8)(25)cos(35)

d = 19

Arithmetic mean: The sum of the data divided by the number of data points. (For the first set of data: (30+25+23+41+39)/5 = 31.4)

Median: The middle value when the data is arranged in order. (For the first set of data: 30, 23, 25, 39, 41 => 25)

Mode: The value that appears most frequently in the data. (For the first set of data: No value appears more than once, so there is no mode.)

Range: The difference between the highest and lowest values in the data. (For the first set of data: 41-23 = 18)

B.

To find the upper and lower quartile, you need to first arrange the data in order and then divide it into four equal parts.

Lower quartile (Q1) is the median of the lower half of the data.

Upper quartile (Q3) is the median of the upper half of the data.

For the first set of data: Q1 = (23+25)/2 = 24, Q3 = (39+41)/2 = 40

7th and 50th Percentile:

To find 7th percentile, pick 7th item from ordered data set and if not possible then take the average of 6th and 8th items.

To find 50th percentile, pick the median of the data set.

For the first set of data: 7th percentile = 25, 50th percentile = 25

C.

Variance: A measure of the spread of the data. It is calculated by taking the average of the squared differences from the mean.

Coefficient of variation (CV) : A normalized measure of the spread of the data. It is the ratio of the standard deviation to the mean.

D.

Pearson coefficient of skewness: A measure of the asymmetry of the data about the mean. A positive skewness indicates that the tail on the right side of the probability density function is longer or fatter than the left side. Conversely, a negative skewness indicates that the tail on the left side is longer or fatter than the right side.

Kurtosis: A measure of the "peakedness" of the data. A high kurtosis means that the data has heavy tails (outliers) or a distinct peak near the mean, whereas a low kurtosis means that the data has light tails (no outliers) or a flat peak near the mean.

The slope-intercept form of the equation of the given line which passes through the point (2, 7) and has a slope of 8 is:

     y = 8x - 9

What is meant by slope-intercept form of the line equation?

The slope (m) and the y-intercept (b) of a line are highlighted in the slope-intercept form of linear equations (y=mx+b). One of the most popular ways to represent a line's equation is in the slope-intercept form of a straight line. When the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis) are known, the slope-intercept formula can be used to determine the equation of a line. The equation of a line is the equation that each point on the line fulfils.

Given the line passes through a point  (2,7) and the slope is 8.

When a point on the line and slope are given, the equation of the line is:

y - y₁ = m ( x - x₁)

m = slope  = 8

Substituting,

y - 7 = 8 ( x - 2)

y - 7 = 8x -16

y = 8x - 9

Therefore the slope-intercept form of the equation of the given line is:
