The relation that represents a function is the mapping in: B.

A relation is defined as a function if each of the x-value (domain element of input) in the relation corresponds to exactly one y-value (range element of output).

The relation in option A is not a function because it has two different y-values, 7 and 5 that corresponds to an x-value, 6. The relations in option C and D do not represent a function also.

The mapping in option B shows a relation where each x-value (domain element) is related or corresponds to only one y-value (range element). Therefore, it is a function.

The rate of change in enrollment from 2010 to 2020 is -53 students per year.

Interpretation:

A negative rate of change (-53 students per year) means that the enrollment in the school decreased over the 10-year period from 2010 to 2020. On average, the school lost 53 students per year during this time frame. This decline in enrollment may have implications for the school's resources, budget, and programs, as it indicates a reduction in the student population over the given period.

Here, we have,

To find the rate of change in enrollment from 2010 to 2020, we can use the formula for calculating the rate of change:

Rate of change = (Change in enrollment) / (Time interval)

Where:

Change in enrollment = Enrollment in 2020 - Enrollment in 2010

Time interval = Year in 2020 - Year in 2010

Let's calculate the rate of change:

Change in enrollment = 715 - 1245 = -530

Time interval = 2020 - 2010 = 10 years

Rate of change = (-530) / 10 = -53

The rate of change in enrollment from 2010 to 2020 is -53 students per year.

The missing co-ordinate r = 8

(6,9) and (r,-1) are two points on a line whose slope is given as -5.

Slope of a line is the change of y co-ordinates divided by the change in x co-ordinates between two points on a line.

Take (x₁, y₁) = (6,9) and (x₂, y₂) = (r, -1).

The slope of a line is given by,

Slope, m = (y₂-y₁)/ (x₂-x₁)

⇒  -5 = (-1-9)/(r-6)

⇒ -5 = -10/(r-6)

⇒ 1 = 2/(r-6)

⇒ r-6 = 2

⇒ r = 2+6

⇒ r = 8

So the points are (6,9) and (8,-1).

Answer:

x = 10

Step-by-step explanation:

The internal angles of a triangle sum 180°

74° + 45°+ (8x-19)° = 180°

119 + 8x - 19 = 180

119 - 19 + 8x = 180

100 + 8x = 180

8x = 180 - 100

8x = 80

x = 80/8

x = 10

Check:

74 + 45 + (8x-19) = 180

1100 + 8*10 = 180

100 + 80 = 180

What is coordinate geometry?

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that M is the midpoint of CF for the points c(4,10) and f(10,10). To calculate the segment MF first let us calculate the midpoint M.

M = [ ( x₁ + x₂ ) / 2, ( y₁ + y₂ ) / 2 ]

M = [( 4 + 10 ) /2 , ( 10+10 ) / 2]

M = ( 7, 10)

The length of the segment MF will be:-

D = √ [ ( y₂ - y₁ )² + ( x₂ - x₁ )² ]

D = √ [ ( 10-10 )² + ( 10 - 4 )² ]

D = √36

D = 6

Therefore, the length of the segment MF will be 6 units.

The amount of interest would be $8.4 Charis received at the end of two years.

Simple interest is defined as interest paid on the original principal and calculated with the following formula:

S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100

We have been given data as:

Principal (P) = $140

Rate of Interest (R) = 3% = 3/100 = 0.03

Time (T) = 2 years

⇒ Simple interest  = P × R × T

Substitute the value of P, R, and T in the above formula,

⇒ Simple interest = 140 × 0.03 × 2

⇒ Simple interest = $8.4

Therefore, the amount of interest would be $8.4 Charis received at the end of two years.

The measure of ∠M and ∠L is 45 degrees. then the measure of ∠N  is 90 degrees.

An angle requires two straight line/ line segments/rays, such that they're connected on one of their endpoints. The point of their joint is called vertex of that angle. Those two line segments forming it are called arms of that angle. The angle is the degree of rotation that it will take for the moving side to go from initial side to the position it is currently on.

Given that the angle L M N the measure of angle L is equal to the measure of angle M.

∠L = ∠M

Also, the measure of angle N is twice the measure of angle M.

∠N = 2∠M

The measure of each angle in angle L M N would be;

∠L + ∠M + ∠N = 180

∠M + ∠M + 2∠M = 180

4∠M = 180

∠M = 180/4

∠M = 45

∠M = ∠L = 45 degrees

∠N = 2 x 45 = 90

Therefore, the measure of ∠M and ∠L is 45 degrees. then the measure of ∠N  is 90 degrees.

If the company earned a total of $37,500 in interest last year, how much cash did they keep in the bank is; $937,500.

This is about the concept of compound interest which is defined as the interest on savings that is calculated on both the initial principal and the accumulated interest from previous periods.

From the question, let us make x to represent the amount of cash.

Now, we are told that one portion of it pays 0.5%and as such this will be 0.005x.

Now, the other portion pays 3.5% and as such this is 0.035x.

Combining both knowing that the total the company earned in the last year was $37,500 and we have;

0.005x + 0.035x = 37500

0.040x = 37500

Solve for x to get;

x = (37500)/(0.04)

x = 937500

Therefore, the company started with $937,500.

Kelvin should fasten each piece of wood approximately 7.1 from the corner.

The right-angled triangle's relationship between its three sides is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The square of a triangle's hypotenuse is equal to the sum of its other two sides' squares, according to the Pythagoras theorem. The hypotenuse's square is equal to the sum of the squares of the other two sides if a triangle has a straight angle (90 degrees), according to the Pythagoras theorem. Keep in mind that BC² = AB² + AC² in the triangle ABC signifies this. Base AB, height AC, and hypotenuse BC are all used in this equation. The longest side of a right-angled triangle is its hypotenuse, it should be emphasized.

a² + b² = c²

The standard equation is 7x + y = 9

layoff Ax + By = C is the usual form for two-variable direct equations. A standard form direct equation is, for case, 2x + 3y = 5. When an equation is given in this format, chancing both intercepts is rather simple( x and y). When trying to break systems involving two direct equations, this form is also relatively helpful.

Given

7x + 3 = 5 and y - 1 = 6

Add the bottoms from the two given equations to produce a single standard-form equation.

By shifting the constant fromR.H.S. toL.H.S., the equations are reset to zero.

7x + 3 - 5 = 0

7x - 2 = 0----( 1)

y - 1 = 6

y - 1 - 6 = 0

y - 7 = 0-----( 2)

Equation 1 and equation 2 must be combined.

7x - 2 + y - 7 = 0

7x + y - 9 = 0

layoff Ax + By = C is the equation's conventional form.

A, B, and C are integers and x and y are variables in this type of equation.

Accordingly, the common equation is

7x + y - 9 = 0

7x + y = 9

therefore the standard equation is 7x + y = 9
