The graphing of linear functions can be done in three basic ways. Plotting points and then drawing a line through them is the first method. The second method makes use of the slope and y-intercept.

Transformations of the identity function f(x)=x f (x) = x are the third option.

There is a single solution, an infinite number of solutions, and there is no solution in an equational system. The number of solutions to a system can be determined algebraically and graphically.

Linear equations can take one of three main forms: the standard form, the point-slope form, and the slope-intercept form.

The term "linear" refers to the graph of a linear equation with two variables. Plotting these two points and drawing the line that connects them are (x1,y1) and (x2,y2).

The equation is an identity because it is true for all values of the variables within the equation.

The equation is an identity because it is true for all values of the variables within the equation. This means that when the equation is evaluated for any given values of the variables, the left-hand side and the right-hand side of the equation will be equal. This is different from an equation that is not an identity, which will only be true for certain values of the variables. An identity equation is also different from an equation that is not an identity, which may be true for some values of the variables but not for all values.

In addition to utilising handspan, foot span, and other methods, one can measure length in many units, such as centimetres, inches, metres, and so on. The several types of units used to measure length can be divided into two categories: standard units and non-standard units.

The number of digits in the base-numerical for, as determined by the formula, determines a number's base length.

HF = 10x + 6

VH = 8 x – 14 and

FV = 4x+10

Substitute

8x - 14 + 4x + 10 = 10x +6

12x - 4 = 10x + 6

12x - 10x = 6 + 4

(i) The required frequency is 12 for the class interval 50-60.

(ii) The mean height of students in a class is 155.3.

(iii) The median of the given data is 33.

(i)

Class Interval    Frequency f   Mid-value x         fx

0-10                          22                  5                    110

10-20                        24                  15                  360

20-30                       35                  25                  875

30-40                       30                  35                  1050

40-50                       27                  45                  1215

50-60                        m                  55                  55m

60-70                        6                   65                  390

70-80                        4                   75                  300

                            ∑f = 148+m                  ∑fx = 4300+55m

The mean of the data set shown in the table above is 31.

mean = ∑fx/∑f

Substitute the known values in the above formula, and we get

31 = (4300+55m)/(148+m)

31(148+m) = 4300+55m

4588 +31m = 4300+55m

55m - 31m = 4588 - 4300

24m = 288

m = 288/24

m = 12

Thus, the required frequency is 12 for the class interval 50-60.

(ii)The table below summarizes the data about the heights of students in a class.

Height (in cm)   (x)    d = (x -A)/10  Number of students (f)       fd

130-140            135       -2                   8                                     -16  

140-150            145       -1                    6                                      -6

150-160            155        0                   14                                      0

160-170             165        1                   20                                    20

170-180             175        2                   12                                     24

                                                           ∑f = 60                        ∑fd = 22

Mean = A + ∑fd/∑f

Mean = 155 + 22/60

Mean = 155 + 0.3

Mean = 155.3

So, the mean height of students in a class is 155.3.

(iii) Given that the mean of data is 27 and the mode is 45

Mode = 3Median - 2Mean

45 = 3Median - 2(27)

45 = 3Median - 54

3Median = 54 + 45

Median = 99/3

Median = 33

Thus, the median of the given data is 33.

The measure of an angle if it is five times its complement: 75 degrees

Let us assume that the complement of the angle measures m degrees.

we have been given the measure of the angle is five times its complement.

So we get the measure of the angle = 5 × m

We know that two angles are complementary when their measures add to 90 degrees.

So we get an equation, m + 5m = 90

We solve above equation to find the value of m.

m + 5m = 90

6m = 90

m = 90/6

m = 15 degrees

This means, the measure of complement of the angle is 15 degrees.

Given that,

a store has 25% off sale on coats.

Discounted price of one coat = $34.50

We have to find the original price of the coat. Let it be x.

The midsegment linking the midpoints of two sides of a triangle is parallel to the third side of the triangle, and its length is half that of the third side, according to the midsegment theorem.

The midpoints of the sides AB, BC, and AC are points M, N, and K. The Triangle Midline Theorem states that

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality.

In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. Therefore, inequality emerges from a lack of balance.

The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in place of the equals sign. It is an illustration of inequity. This shows that the left half, 5x 4, is bigger than the right part, 2x + 3. Finding the x numbers for which the inequality holds true is what we are most interested in.

Polynomial inequality, rational inequality, and absolute value inequality are the various types of inequalities that can exist in mathematics.

The numbered choice 7 represents a value for x which will make B a function.

A relation between a collection of inputs and outputs is known as a function. A function is a connection between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.

Given:

A relation B =  {(4,2), (5,-3), (12,4), (-3,6), (x, 7)}.

To prove that the relation is a function:

Each input value gives only one output value.

Input →  output

4 →  2

5 →  -3

12 →  4

-3 →  6

x  → 7.

Simplifying radicals is the process of reducing a radical expression to its simplest form. There are several ways to simplify radicals, but the most common method is to factor .

The number or expression inside the radical sign and extract any perfect nth root factors.For example: √36 = √(36) = √(6*6) = √(6^2) = 6

Here, 36 can be factorized into 6*6, and since 6 is a perfect square, we can simplify the radical as 6.

Another example: √100 = √(100) = √(10*10) = √(10^2) = 10

Here, 100 can be factorized into 10*10, and since 10 is a perfect square, we can simplify the radical as 10.

Another way to simplify radicals is to use the product property of radicals which states that: √(a*b) = √(a) * √(b)

For example: √(1215) = √(12) * √(15) = √(4355) = √(43) * √(55) = 2√(3) * 5 = 6√(3)

Here, 1215 can be factorized into 4355. And since 43 is a perfect square, we can simplify the radical by taking the square root of 43 and 5*5.

You can simplify radicals as much as possible by applying these methods.

It's important to note that not all radicals can be simplified completely, in some cases we can simplify the radical as much as possible but still have an irrational number inside the radical.

Simplifying radicals is a useful process in algebra and trigonometry, it helps to simplify the expressions and make calculations easier.
