Using easy mathematical operations, we know that the value of x in the given rectangle is 6 cm.

An operation, in mathematics, is a mathematical function that transforms zero or more input values into a precisely defined output value.

The arity of the operation is influenced by the number of operands.

PEMDAS, parenthesis, exponents, multiplication, and division.

So, the value of x will be:

The given two rectangles have similar sides.

2cm is similar to 4cm.

3cm is similar to xcm.

Now, we can calculate x as follows:

2/4 = 3/x

2x = 4×3

2x = 12

x = 12/x

x = 6

Therefore, using easy mathematical operations, we know that the value of x in the given rectangle is 6 cm.

The value of n in the line segment is - 9 / 4.

The length of a line segment can be found as follows:

Two point of the line segment are 2n + 9 / 2 and 9 / 2. The distance of the line segment is 9 / 2.

Therefore, let's find n as follows:

9 / 2 - (2n + 9 / 2) = 9 / 2

9 / 2 - 2n - 9 / 2 = 9 / 2

9 / 2 - 9 / 2 - 2n = 9 / 2

- 2n = 9 / 2

cross multiply

-2n × 2 = 9

- 4n = 9

divide both sides by -4

n = 9 / -4

n = - 9 / 4

The equation of the line will be y = 12x -3 and the graph of the line with the given y-intercept and slope is shown below.

First, let us understand the slope intercept form of a line:

The equation of the line is written in the slope-intercept form, which is: y = mx + b, where m represents the slope and b represents the y-intercept.

We are given:

(0, −3), m = 12.

We need to determine the graph of the line with the given y-intercept and slope.

To find the value of b;

substitute the given values in the equation of the line, we will get;

y = mx + b

-3 = 12 *0  + b

b = -3

So, the equation of the line will be:

y = 12x -3

Thus, the equation of the line will be y = 12x -3 and the graph of the line with the given y-intercept and slope is shown below.

Step-by-step explanation:

Since -1 is greater the values given then x is less than -1

The greatest common factor, GCF, of 8y, -12x, and 4xy is 4

From the question, we are to determine the greatest common factor of the given expressions.

The given expressions are 8y, -12x, and 4xy

To determine the greatest common factor, we will express each of the expressions as a product of their factors.

8y = 2 × 2 × 2 × y

-12x = 2 × 2 × 3 × -x

4xy = 2 × 2 × x × y

From above, we can observe that the greatest common factor is

The original price of purchasing is $825 plus 7% sales tax, then the interest will be $9.20. Hence, option D is correct.

The Latin term "per centum," which signifies "by the hundred," is where the word "percentage" originally came from. With 100 as the denominator, percentages are fractions. To put it another way, it's the relationship here between a component and a whole, in which the value of the whole is always assumed to be 100.

As per the given data in the question,

The original purchase price = $825

The sales tax = 7% of $825 = 825 × 7/100 = $57.75

Total credit = $825 + $57.75 = $882.75

The monthly interest rate = 12.5%/12 = 1.0417%

Interest = $882.75 × 1.0417/100

The equation of the line that has a slope of -2 and x-intercept of -1 in point slope form is y = -2(x + 1).

Linear equations can be represented in different form such as point slope form, slope intercept form, general form and standard form.

Therefore, let's represent the equation of the line in point slope form.

Using point slope form,

y - y₁ = m(x - x₁)

where

Therefore, the equation of the line has a slope of -2 and an x-intercept of -1.

The slope of a line is the change in the dependent variable with respect to the change in the independent variable.

The x-intercept is where a line crosses the x-axis. The x-intercept is the value of x when y = 0.

hence,

m = -2 and (-1, 0)

x₁ = -1

y₁ = 0

Therefore,

y - 0 = -2(x + 1)

Answer:

[tex]f(x)=6(x-2)^2+18[/tex]

Step-by-step explanation:

Given quadratic function:

[tex]f(x)=6x^2-24x+42[/tex]

To complete the square, begin by grouping the x terms within parentheses:

[tex]\implies f(x)=(6x^2-24x)+42[/tex]

Factor out the coefficient of x²:

[tex]f(x)=6\left(x^2-4x\right)+42[/tex]

Add the square of half the coefficient of the term in x inside the parentheses, and subtract the distributed value outside the parentheses:

[tex]\implies f(x)=6\left(x^2-4x+\left(\dfrac{-4}{2}\right)^2\right)+42-6\left(\dfrac{-4}{2}\right)^2[/tex]

Simplify:

[tex]\implies f(x)=6\left(x^2-4x+\left(-2\right)^2\right)+42-6\left(-2\right)^2[/tex]

[tex]\implies f(x)=6\left(x^2-4x+4\right)+42-6\left(4)[/tex]

[tex]\implies f(x)=6\left(x^2-4x+4\right)+42-24[/tex]

[tex]\implies f(x)=6\left(x^2-4x+4\right)+18[/tex]

Factor the perfect square trinomial inside the parentheses:

[tex]\implies f(x)=6(x-2)^2+18[/tex]

Comparing the derived equation with the vertex formula, the vertex of the derived equation is (2, 18).  Hence the completion of the square is correct.

A. When x = -1, the value of y is equal to 3.

B. When y = 7, the value of x is equal to 1.

C. The y-intercept of the graph is equal to -2.5.

D. The x-intercept of the graph is equal to 5.

E. The slope of the line is equal to -1.75

F. The equation of the line is equal to y = -1.75x - 2.5

In Mathematics, the y-intercept of any graph such as a linear function, generally occur at the point where the value of "x" is equal to zero (x = 0).

Mathematically, the slope-intercept form of a line can be calculated by using this equation:

y = mx + c

Where:

Making slope (m) the subject of formula, we have the following:

Slope, m = (y - c)/x

Slope, m = (1 - (-2.5))/-2

Slope, m = (1 + 2.5)/-2

Slope, m = -3.5/2

Slope, m = -1.75.

For the equation of this line, we have:

y = mx + c

y = -1.75x - 2.5

a) The missing section is 24 units.

b) The missing section is 18 units.

c) The missing section is 10 units.

The missing sections can be computed using the mathematical operations of division and multiplication.

The percentage of lightbulb replacement requests numbering between 32 and 36 is 34

According to the question,

The distribution of the number of daily request is bell-shapes means Number of daily request follows Normal distribution

Mean of normal distribution : μ = 36

Standard deviation : σ = 4

Let the lightbulb replacement requests number be "x"

So, the probability of lightbulb replacement requests numbering between 32 and 36 = P(32 < x <36)

below 36 i.e. mean of normal

32 = 36 - 4 is probability between one standard deviation and below mean

Percentage between mean ± standard deviation is always 68%

so , percentage of lightbulb replacement requests numbering between 32 and 36 will be half of 68% as mean + standard deviation is excluded

= 68/2
