Explain how you can represent a proportional relationship using an equation.

Answer:

Step-by-step explanation:

No it does not hold for division nor subtraction. An example would be 8÷(4÷2)≠(8÷4)÷2. You would get two complete different answers. For the first equation you would get 4 where as for the second equation you would get 1.

Using the rule for a dilation, it is found that:

1. The table with the coordinates is given by the first image.

2. The graph of the dilated triangle is given by the second image.

3. The rule is: (x,y) -> (1.5x, 1.5y).

When a figure is dilated by an scale factor of a, each vertex of the figure is multiplied by the scale factor of a, hence the rule is given by the following vector:

(x,y) -> (ax, ay).

The coordinates of the vertices of the pre-image are given as follows:

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

The dilation has a scale factor of 1.5, hence the rule for the calculation of each vertex of the image, considering the pre-image, is given as follows:

(x,y) -> (1.5x, 1.5y).

Then the vertices of the image will be given as follows:

A'(-3, -3), B'(3,3), C'(6, -3).

Each coordinate of A, B and C was simply multiplied by 1/2, and the triangle with these vertices is given by the second image at the end of the answer.

The problem is incomplete, and is given by the first image at the end of the answer.

The exponential function that shows the amount of money paid for membership x months after the beginning of the year is given by y = 32(1.18)ˣ.

There are two possibilities for the exponential function: it can be increasing or decreasing. Being increasing means that as the value of x increases, the value of f(x) also increases; being decreasing means that as the value of x decreases, the value of f(x) also decreases.

Let y represent the amount of money paid for membership x months after the beginning of the year. Abby's gym membership will increase by 18% a month. This is an exponential function.She is currently paying $32 a month, hence:y = 32(1 + 0.18)ˣy = 32(1.18)ˣ

7.5cm distance a spring when a force of 270 newtons stretch the same spring.

A force is an influence that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Given Data

A force of 180 newtons stretches a spring 5 cm

If we consider F to be the force and x to be the extension, then:

F = kx

F = 180

x = 5

Equating

180 = 5k

k = 36

F = 36x

Force of 270:

Step-by-step explanation:

The value of t for the angles of the given triangle will be 30.67.

The straight angle is equal to the total of the angles of a triangle. Three angles, one at each vertex and bounded by two neighbouring sides, make up a triangle. For a very long period, it was unknown if there were any alternative geometries for which the total is different.

The triangle has three sides and is a two-dimensional figure having the sum of the angles of 180 degrees.

In the given image the three angles are 2t, t + 8, and t - 12. The value of t will be calculated as:-

2t + t + 8 + t - 12 = 180

4t - 4 = 180

4t = 184

t = 184 / 4

t = 30.67

Therefore, the value of t for the angles of the given triangle will be 30.67.

Answer:

Step-by-step explanation:

Let's write everything in slope-intercept format of y=mx+b, where m is the slope and b is the y-intercept.

x+3y=15

3y= -x + 15

y = (-1/3)x + 5

Parallel lines will have the sam slope, in this case -(1/3),  So the new line will be:

y = (-1/3)x + b

We need to fijnd a value of b that will force the ine through point (6,1).  Enter (6,1) in the equation and solve for b:

y = (-1/3)x + b

1 = (-1/3)(6) + b

1 = (-2) + b

b = 3

The parallel line is:

   y = (-1/3)x + 3

The maximum number of dresses that Amanda can send to be ironed is 8.

For the given question;

Total budget of Amanda = $100.

Price of washing = $8 per dress.

Price of ironing = $5 per dress.

Total number of dress to be washed = 7.

Let x be the number of dress to be send for ironing.

The inequality becomes.

5x + 7×8 ≤ 100

5x + 56 ≤ 100; is the required inequality.

For finding the x, equate the value.

5x + 56 ≤ 100

5x ≤ 44

x ≤ 8.8

But x must be less, then.

x = 8 dress.

The line graph is created using the close price of the stock each day.

In Trading and securities, a stock is also known to as equity and it can be defined as a financial security which represents a stockholder's ownership of a fraction of a corporation.

An closing price can be defined as the official price at which a financial security first trades at the closing of an exchange on a stock market, during a regular trading session.

This ultimately implies that, a closing price is the price at which the last financial transactions are completed or the last bids and offers are made by eligible customers on a stock market.

In this context, we can reasonably infer and logically deduce that the close price of the stock each day was used to create the line graph.

By using the concept of uniform rectilinear motion, the distance surplus of the average race car is equal to 3 / 4 miles. (Right choice: A)

In accordance with the statement, both the average consumer car and the average race car travel at constant speed (v), in miles per hour. The distance traveled by the vehicle (s), in miles, is equal to the product of the speed and time (t), in hours. The distance surplus (s'), in miles, done by the average race car is determined by the following expression:

s' = (v' - v) · t

Where:

Please notice that a hour equal 3600 seconds. If we know that v' = 210 mi / h, v = 120 mi / h and t = 30 / 3600 h, then the distance surplus of the average race car is:

s' = (210 - 120) · (30 / 3600)

s' = 3 / 4 mi

The distance surplus of the average race car is equal to 3 / 4 miles.

Answer: 14 : 12

Step-by-step explanation:

Answer: 14:12

Step-by-step explanation: To find the ratio, you would either multiply or divide the two numbers by the same number, and you would get a simplified ratio or an equivalent one. Because 7:6 is simplified, we have to find an equivalent ratio, meaning we multiply. If we multiply 7 by two, we get 14. Multiply 6 by two to get 12. So, the answer is 14:12. Divide both 14 and 12 by two to get back to 7:6.

The launching angle of the plane which has reached a height of 35000 ft is 15°

Let the distance travelled by the airplane horizontally be AB

The height reached by the airplane be BC

Thus AB = 130000 ft

        BC = 35000 ft

The launching angle of the airplane can be found using the formula

                                   tanθ = opposite / adjacent

                                                    (or)

                                           tanθ  = BC / AB

Let us substitute the known values in the above equation, we get

                                          tanθ  = 35000/130000

                                          tanθ  = 0.2692

                                               θ  = tan⁻¹ (0.2692)

                                               θ  = 15.067°

                                               θ  ≅ 15°
