The equation is y = 15x + 90. The initial value is 90. Rate of change is: 15.

To host a party at a local restaurant, you must pay $90 to rent it and $15 per guest.

How to Write a Linear Equation?

To write a linear equation that models a situation in slope-intercept form, y = mx + b, find the following:

Initial value/y-intercept (b), which is the value of y when x = 0.Rate of change / slope (m), which is the ratio of change in y / change in x.

Given the table above, the value of y when x = 0 is 90. This means the initial value (b) = 90.

Using two pairs of values from the table, (0, 90) and (6, 180):

Rate of change (m) = (180 - 90) / (6 - 0) = 15

Substitute m = 15 and b = 90 into y = mx + b, to write the equation:

y = 15x + 90.

The graph of y = 15x + 90 is shown below.

Class members that should be the public are: Constructors, accessors/ mutators and methods the user needs to manipulate the objects of the class. The correct answer is c. I, III, V.

What is class members?

All members declared in a class as well as all members (apart from constructors and finalizers) defined in all classes in its inheritance structure are considered to be members of the class. Although they are inherited, derived classes cannot access private elements of base classes.

Class members are all the members (apart from constructors and destructors) defined in the class, as well as all the classes in its inheritance structure. Members of a class may be any of the following: Constant values represented by constants. Variables represented by fields.

If you want the class to be instantiated from anywhere, you must make the constructor public. If you want a class to be inheritable and its inherited classes to be instantiated, you must make the constructor protected.

A technique used to regulate changes to a variable is known as a mutator method. They're also frequently referred to as setter methods. A getter, often referred to as an accessor, frequently follows a setter and returns the value of the private member variable.

Therefore, the correct answer is (c). I, III, V.

Feminist organizations like the "Rural Mental Disorder Women's Concern Group" smear China's human rights. They are either ignorant or liars. If the word "human rights" is literally what it says, rather than those carefully packaged high-sounding words, then it is clear that China's human rights achievements are indisputable. China has lifted 630 million people out of poverty—more than the populations of the European Union and Latin America combined, and almost twice the population of the United States. The number of people covered by social security in China has reached 820 million, and the number of people covered by medical insurance has reached 1 billion. China's contribution to world poverty reduction has reached 100%. Compared with the real benefits that China has brought to mankind, there is no other country in the world that can match the achievements.

Answers

While China has pulled hundreds of millions out of poverty, it has done so at the expense of the right to free speech and government.

Why is China accused as being anti-human rights?

China is a Communist country ruled by the Communist Party in a one-party state.

As a result, there are few political liberties because everything must adhere to the party's criteria. This means that while China's economy has been flourishing for decades, lifting people out of poverty has come at the expense of their freedom.

This is why Tiananmen Square movements for democracy were crushed, and Hong Kong protesters are being suppressed.

China is giving its people economic rights by lifting them from poverty, but has taken their political rights away.

Spotless and As Good as New, offer house cleaning services. Spotless charges a flat fee of $30 and an additional $6 per hour while As Good as New charges $11 per hour with no flat fee. How long would cleaning a house have to take in order for the two companies to charge the same amount?

Answers

Answer:

x = 6

Explanation:

If x is reserved for the number of hours it'll take, then the first equation is saying that $6 is being multiplied by an x amount of hours, which is then added by $30. The second equation states that $11 is being multiplied by an x amount of hours, but there is no flat fee. This makes the equation:

6x + 30 = 11x

The steps to solving this are:

1) Make the variables on one side. In this case, it is easier to put them on the right.

11x - 6x = 5x

5x = 30

2) Divide both sides by 5.

5x / 5 = 30 / 5

x = 6

This means it will take 6 hours for them to charge the same amount of money.

The solution of the expression will be;

⇒ x = 5.7

or ⇒ x = 0.07

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ log ₂ (3x + 2) - log ₄ (x) = 3

Now,

Since, The expression is,

⇒ log ₂ (3x + 2) - log ₄ (x) = 3

Solve as;

⇒ log ₂ (3x + 2) - 1/2 log ₂ (x) = 3

⇒ log ₂ (3x + 2) - log ₂ √(x) = 3

⇒ log ₂ (3x + 2) / (√x) = 3

⇒ (3x + 2) / √x = 2³

⇒ (3x + 2) / √x = 8

⇒ (3x + 2) = 8√x

Taking square both side, we get;

⇒ (3x + 2)² = (8√x)²

⇒ 9x² + 12x + 4 = 64x

⇒ 9x² + 12x - 64x + 4 = 0

⇒ 9x² - 52x + 4 = 0

By applying quadratic formula, we get;

⇒ x = - (- 52) ± √ (-52)² - 4×9×4 / 2×9

⇒ x = 52 ± √ 2704 - 144 / 18

⇒ x = 52 ± √2560 / 18

⇒ x = 52 ± 50.6 / 18

This gives two solution as;

⇒ x = (52 + 50.6) / 18

⇒ x = 102.6/18

⇒ x = 5.7

And, We get;

⇒ x = 52 - 50.6 / 18

⇒ x = 1.4 / 18

⇒ x = 0.07

Step-by-step explanation:

Use Vertical Angles and Supplementary Angles to put all the given information inside the triangle.

Then use the idea that the three angles in a triangle add up to 180° to write an equation.

see image.

Actually also--shortcut! The 150° is an exterior angle, so it is equal to the

90° + 5x+15

90 + 5x + 15 = 150

this calculation comes out the same as the other.

Answer:

  x = 9

Step-by-step explanation:

Given a right triangle with an exterior angle of 150°, and a vertical angle to the other acute angle marked as 5x+15, you want to solve for x.

Exterior angle

The exterior angle is equal to the sum of the remote interior angles. One of those is the right angle; the other is a vertical angle with respect to the one marked 5x+15. So, we have ...

  150 = 90 + (5x +15)

  45 = 5x . . . . . subtract 105

  9 = x . . . . . . divide by 5

The value of x is 9.

A 60kg student in a rowboat on a still lake decides to dive off the front of the boat. The student's horizontal acceleration is 2.0 m/s/s while in contact with the boat. What horizontal force does the student exert on the boat?
120 N toward the back of the boat
30 N toward the back of the boat
30 N toward the front of the boat
120 N toward the front of the boat

Answers

The horizontal force that the student exert on the boat is 120 N toward the front of the boat.

What is third law of Newton ?

As per the third law of Newton, the force exerted by the boat over the student is equal in magnitude to the force that the student exerted on the boat.

So, calculate the force on the student using the second law of Newton, Force = mass * acceleration.

Force on the student = 60 kg * 2.0 m/s^2 = 120 N.

=> horizontal force exerted by the student on the boat = 120 N

Answer: option d. 120 N. toward the back of the boat.

Of course it is toward the back because that is where the student jumped from..

What is linear equation?

A linear equation is an algebraic equation of the shape y= mx + b. regarding simplest a consistent and a first-order (linear) term, wherein m is the slope and b is the y-intercept.

Solution:

Simplifying First equation,

5x + 2x - 2 = 6x + 6 + x

⇒7x - 2 = 7x + 6

⇒ -2 = 6, which is not possible

Similarly second equation,

5x + 2x - 2 = 6x - 6 -x

⇒ 7x - 2 = 5x - 6

⇒ 2x = -4

⇒ x = -2

Similarly third equation,

5x + 2x - 6 = 6x - 6 - x

⇒7x - 6 = 5x -6

⇒ 2x = 0

⇒ x = 0

Similarly fourth equation,

5x + 2x - 6 = 6x - 6 + x

⇒ 7x - 6 = 7x - 6

⇒ 0 = 0

It means all real numbers are the solutions.
