Equation:  y = 12x + 0

Explaination: A proportional relationship is one in which two quantities vary directly with each other. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other.

Answer:

2(x-2) + 3 (4x-1) = 0​

x = 1/2

Answer:

For one adult it costs $15

For one child it costs $10

Step-by-step explanation:

So..

One adult = $15

Two children = $20 10×10

= $35

Then..

Two adult = $30 15×15

Three children = $30 10×10×10

= $60

Answer:

Step-by-step explanation:

Given function:

The complete video games can be expressed as positive integers or whole numbers, so the domain is whole numbers.

Correct choice is (4)

Answer:

Whole Number

Explanation:

Domain : The set of all the input values (i.e. the value of x ) in the function is called domain

The daily cost of production in a video game factory is calculated using c(x) = 400 + 25x

Cost expression : C(x) = 400 + 25x

Cost expression : C(x) = 400 + 25x

As x defines the number of complete video, since number of video cannot be negative.

1) Integers : integers are the numbers which can be positive, negative or zero, but cannot be a fraction

As, number of videos cannot be negative

so, x cannot be any integers

So, Integers is not the domain

2) Positive real numbers : Real numbers are the numbers which include both rational and irrational numbers.

As the x represent the complete number of video games, thus, x cannot be irrational

Hence, Positive real numbers is not the domain

3) Positive Rational Number : a number is expressed in the form of p/q then it is a rational number

The number of videos are in the complete number, so a fraction cannot be a complete number, thus, rational number cannot be a domain.

4) Whole Number : Whole numbers include natural numbers that begin from 1 onwards

As Numbers of videos are the complete number, and they are always positive, which is the defination of whole number, Domain is whole number

Answer:Number of students eating lunches other than salads or sandwiches= 10

Step-by-step explanation:

Number of students in the cafeteria=20

Number of students eating salads=1/10 X 20= 2

Number of students eating sandwiches= 2/5 x 20 = 8

Number of students eating lunches other than salads or sandwiches=

Number of students in the cafeteria -(

Number of students eating salads +Number of students eating sandwiches)

=20-(2+8)

=20-10

=10 students.

Answer:

The answer is D. 33-42

Step-by-step explanation:

Because it says that Alia got 42 fewer jelly beans than Kelly did so you would do 33-42.

the answer is less than 1/8 of a pizza. 1/4 divided by 6 = 1/4 x 1/6 = 1/24

and it is less than 1/8, pretty obvious.

Answer:

We would use the Law of Cosines to solve the question.

m∠ W = 121.8°

Step-by-step explanation:

In triangle UVW, u = 20, v = 47. and w = 60. To find m∠ W,

which law would you use?

The Law we would use to find find m∠W is the Law of cosines, this is because in the question above we are given 3 known sides of a triangle and we are asked to find an unknown angle.

Law of cosines when we are to find an unknown angle =

m∠ W = arc cos [u² + v² - w²/ 2uv]

m∠ W = arccos [ 20² + 47² - 60²/ 2 × 20 × 47]

m∠ W = 121.81159°

Approximately = 121.8°

Answer:

  Vertex: (-1, 4)

  Maximum: f(-1) = 4

  Increasing: (-∞, -1)

  Decreasing: (-1, ∞)

Step-by-step explanation:

The equation can be written in vertex form by "completing the square."

First factor out the leading coefficient from the x-terms.

  f(x) = -(x² +2x) +3

Then add the square of half the x-coefficient inside parentheses. Add the opposite of that amount outside parentheses.

  f(x) = -(x² +2x +1) +3 +1

Write in vertex form.

  f(x) = -(x +1)² +4 . . . . . . . compare to a(x -h)² +k

You can see that the vertex is (h, k) = (-1, 4), and that the vertical scale factor 'a' is negative. This means the vertex is the maximum and the parabola opens downward.

The function will be increasing to the left of the maximum, decreasing to its right.

Vertex: (-1, 4)

Maximum: f(-1) = 4

Increasing: (-∞, -1)

Decreasing: (-1, ∞)

Answer:

Step-by-step explanation:

Area of the circle = πr² = π7.3² = 53.29π

Area of major sector = 53.29π(285/360) ≈ 132.54 cm²

The area of major sector DFE is 132.5 sq.cm , Option C is the right answer.

The region bounded by the two radii and intercepted arc in a circle is called a sector .

The angle made by the radii to the center of the circle is called central angle .

if the measure of the angle is less than 180 degree then it is called minor sector and if the angle is more than 180 degree , it is called Major Sector.

It is given that

The radii of the circle is 7.3 cm

The angle subtended by the major sector at the center is 285 degree.

The area of the sector is given by

= ([tex]\rm \theta[/tex] / 360) * Area of the circle

Area of the circle is πr²

Area of the sector = ( 285 / 360) * (22/7) * (7.3)²

Area of the sector is 132.5 sq.cm

Therefore , The area of major sector DFE is 132.5 sq.cm , Option C is the right answer.
