The coordinate of point c is such that point c is 7/8 of m to j is [ 7/8(x₂ - x₁),  7/8(y₂ - y₁) ].

A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).

Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.

For example (5,3) here 5 will be for the x and 3 will be for the y.

Another example is (9,0) here 9 is for x and 0 is for y.

Let's say the coordinate of m → (x₁,y₁)

j → (x₂ ,y₂)

Now since point c is proportion with 7/8

So,

It will be 7/8 times of difference between of x and y coordinate of points m and j

So,

x = 7/8(x₂ - x₁) and y = 7/8(y₂ - y₁)

Hence "The coordinate of point c is such that point c is 7/8 of m to j is [ 7/8(x₂ - x₁),  7/8(y₂ - y₁) ]".

Solving a system of equations we can see that we need to use 120 ml of the 80% solution, and the other 80ml are of the 50% solution.

Let's define the variables:

We know that we want to make 200ml, then:

x  + y = 200

And the concentration of these 200ml must be of 68%, then the concentrations in the left side and in the rigth side must give the same value, so we can write:

x*0.5 + y*0.8 = 200*0.68

(the concentrations are written in decimal form)

Then we have the system of equations:

x  + y = 200

x*0.5 + y*0.8 = 200*0.68

To solve it we start by isolating x in the first equation:

x = 200 - y

Replacing that in the other equation we get:

(200 - y)*0.5 + y*0.8 = 200*0.68

Now we can solve this for y, we will get:

100 - y*0.5 + y*0.8 = 136

y*0.3 = 136 - 100 = 36

y = 36/0.3 = 120

So we need to use 120 ml of the 80% solution, and the other 80ml are of the 50% solution.

The correct pair matching each type of letter to its correct description would be as follows:

send it to favorably influence employers’ decision on hiring you - thank you letter

state how you meet the job requirements - cover letter

send 3-5 days after submitting your application or résumé - follow-up letter

express your desire to work for a particular company - letter of interest

A 'thank you' letter is a letter written to admit gratefulness for a favor that has been done.  It can also be written in anticipation of a favor to be done. Hence, writing it to a potential employer after an interview is a way of trying to influence the employer's decision on hiring you.

A cover letter, as it relates to job application, is a letter written to express how one meets the requirement for a job. In it, a job seeker would state their qualifications, skills, and experience as it relates to the job they are applying for.

A follow-up letter is usually written to follow up with a situation that one expects that a response should have been given or written just to further emphasize one's interest in something. Writing a follow-up letter after submitting an application for  a job is a way of reminding potential employers of one's desire to take up a job in their firm.

A letter of interest is written to show a desire to work in a particular organization or company irrespective of whether they have got a vacancy.

The values of the composite functions are (f.g)(x) = 2x^3 - 19x^2 + 40x + 25 and (f/g)(x) = 2x + 1

The functions are given as:

f(x) = 2x^2 - 9x - 5

g(x) = x - 5

The composite function (f.g)(x) is calculated as

(f.g)(x) = f(x) * g(x)

This gives

(f.g)(x) = (2x^2 - 9x - 5) * (x - 5)

Evaluate the product

(f.g)(x) = 2x^3 - 9x^2 - 5x - 10x^2 + 45x + 25

Evaluate the like terms

(f.g)(x) = 2x^3 - 19x^2 + 40x + 25

The composite function (f/g)(x) is calculated as

(f/g)(x) = f(x)/g(x)

This gives

(f/g)(x) = (2x^2 - 9x - 5)/(x - 5)

Factorize the numerator

(f/g)(x) = (2x + 1)(x - 5)/(x - 5)

Evaluate the quotient

(f/g)(x) = 2x + 1

If Yasmin is the youngest of three siblings who ages are consecutive integers then Yasmin's age is 18, option B is correct.

Let's assume Yasmin's age is represented by the variable "Y".

Yasmin is the youngest, so her age is the smallest integer among the three siblings' ages.

Since their ages are consecutive integers, we can represent the ages of the three siblings as Y, Y+1, and Y+2.

According to the given information, the sum of their ages is 57.

So we can write the equation:

Y + (Y+1) + (Y+2) = 57

Now, let's solve for Y:

3Y + 3 = 57

Subtract 3 from both sides:

3Y = 54

Divide both sides by 3:

Y = 18

So, Yasmin's age (Y) is 18 years old. Option B is correct.

Important note:

After computing the composition function we must define the domain of the new function.

Example 1:

f(x) = x² and g(x) = x + 4, here the domain of f and g is the set of all real numbers.

⇒ f(g(x)) = f(x + 4) = (x + 4)²

Systems of equation that have the same solution are called equivalent systems.

Given a system of two equations, we can produce an equivalent system by replacing one equation by the sum of the two equations, or by replacing an equation by a multiple of itself.

In contrast, we can be sure that two systems of equations are not equivalent if we know that a solution of the one is not a solution of the other.

Note: This idea of equivalent systems of equations pops up again in linear algebra. However, the examples and explanations in this article are geared to a high school algebra 1 class.

Example 1

We're given two systems of equations and asked if they're equivalent.

System A

−12x+9y=7

9x−12y=6

​

system B

−12x+9y=7

3x−4y=2

​

If we multiply the second equation in System B by 3, we get:

3x−4y=2

3(3x−4y)= 3(2)

9x−12y=6

​

Replacing the second equation of System B with this new equation, we get an equivalent system:

−12x+9y=7

9x−12y=6

The length of the rectangle is 8 feet, width 1 is 7 feet and width 2 is 3.

A rectangle of area 80 square feet is broken and forms two square rectangles of area 56 square feet and 24 square feet, which has a common length.

Area of the rectangle = length × width

Now suppose the length is x feet, and let width 1 be a and width 2 be b.

Therefore we get that

            rectangle first is of area = x a

            rectangle second is of area = x b

Therefore original rectangle area = area of first rectangle + area of the second rectangle

80= x a + x b

80  = x( a + b)

As it is given that the length is common and is greater than both the width of the rectangle

56 = 8 × 7

24 = 8 × 3

So we will take x = 8 and a =7, b= 3

Now put these numbers in the equation to see if they fulfill the criteria

80 = 8( 7 + 3)

80 = 80

Therefore we get a length is 8, a width of 1 is 7, and a width of 2 is 3.

We are given the vertices:

A(-4,4), B(2,-2), and C(-4,-2).

We need to find the perimeter of ABC.

AB = √ ( 2 + 4)² + (-2 - 4)²

AB = √ 6² + 6²

AB = √72

AB = 6 √2 units

BC = √ (-4 - 2)² + ( -2 + 2)²

BC = √ 6²

BC = 6 units

AC = √ ( -4 + 4)² + (-2 - 4)²

AC = √ 6²

AC = 6 units.

Perimeter = AB + BC + AC

Perimeter = 6 √2 + 6 + 6 units

Perimeter = 12 + 6 √2 units.

Perimeter = 12 + 6(1.414) units

Perimeter = 12 + 8.848 units
