the answer is A

x=3/2y+3

Step-by-step explanation:

2x=6+3y

x=3+3/2y

x=3/2y+3 is the solution of the equation  2x-3y=6.

The given equation is 2x-3y=6

We need to solve for variable x in the equation.

Isolate the term with variable x.

Add 3y on both sides of the equation.

2x=6+3y

Now divide both sides by 2

x=3+3/2y

x is the solution of the equation.

x=3/2y+3

Answer:

A = 26.6°

Step-by-step explanation:

To obtain the measure of angle A :

We use the trigonometric relation :

Tan A = opposite / Adjacent

Tan A = 6 / 12

Tan A = 1/2

A = tan^-1(1/2)

A = 26.565°

A = 26.6°

[tex]x=60^{\circ}[/tex]

Step-by-step explanation:

The are 180 degrees in a triangle and 180 degrees on a line. Therefore, call the third angle of the triangle [tex]y[/tex].

The following equation solves for [tex]y[/tex]:

[tex]y+119=180,\\y=61^{\circ}[/tex]

Solving for [tex]x[/tex]:

Answer:

39

Step-by-step explanation:

Find the value of f(x) at both points

f(3) = 3(3)³ + 1 = 82

f(1) = 3(1)³ + 1 =  4

---------------------------

Average Rate of Change is just like slope

Divide the change in f(x) by the change in x

r = (82 - 4) / (3 - 1)

r = 78/2

r = 39

probably linear graph 'cause it's in a straight line

Answer:

Step-by-step explanation:

First graph is correct which satisfies the given informations.

The graph is attached below.

Given:

Becky made a graph to show how far she was from her house.

She started jogging from zero distance from the house when she left and sprinted to the park, so the second and fourth graphs are incorrect.

She then spent some time at the park with some friends before returning home on the same path. The first one is accurate since we can see that for a brief while, the graph is parallel to the time axis, but the third one demonstrates that she hasn't taken a break.

The surface area of the prism is equal to 72 sq inches.

Step-by-step explanation:

Given that,

A rectangular prism with a length of 7 inches, a width of 3 inches, and a height of 1 1/2  inches.

The surface area of a rectangular prism is given by :

[tex]A=2(lb+bh+hl)[/tex]

Put all the values,

[tex]A=2(7\times 3+3\times \dfrac{3}{2}+\dfrac{3}{2}\times 7)\\\\A=2\times 36\\\\A=72\ in^2[/tex]

So, the surface area of the prism is equal to 72 sq inches.

Answer:

Step-by-step explanation:

1. The finance charge is found from the simple interest formula;

  I = Prt

where P is the principal amount, r is the annual rate, and t is the number of years.

24 months is 2 years, so the interest charged is ...

  I = $1900×0.08×2 = $304

The finance charge is $304.

__

2. The monthly payment will be the total amount due, divided by the number of months.

  payment = ($1900 +304)/24 = $2204/24 ≈ $91.83

The monthly payment is $91.83.

Answer:

62704

Step-by-step explanation:

Given 6.2704 x 10^4

To convert to standard form:

6.2704 * 10^4

10^4 = 10*10*10*10 = 10000

6.2704 * 10000 = 62704

Hence, 6.2704 x 10^4 = 62704 in standard form

Answer:

n = 106

Step-by-step explanation:

Given  

p = 0.5 and 1-p = q = 0.5

Margin of error = 0.08  

Confidence level = 90%  

Z score for 90% confidence level =     1.65

As we know -  

Margin of error = z * Sqrt (pq/n)

Substituting the given value, we get –  

0.08 = 1.65 * Sqrt (0.5*0.5/n)

Squaring both the sides and solving, we get  

n = 1.65^2*0.5^2/0.08^2

n = 106.34 = 106

Answer:

Circumference

Step-by-step explanation:

The Circumference is the the distance around a circular region, it could be imagined as the distance covered by running or walking around the track of a circular athletic stadium. The Area in the other hand is used to describe the entire region enclosed within the circle. For instance the area may be described as the entire pitch region of an athletic stadium, if the circular distance is the Circumference, the enclosed region within the circle is the measure of the Area.

Answer:

Sine (30°) = cosine(90-30) = cos(60°) = 1/2

Step-by-step explanation:

The value of the [tex]cos 60^0[/tex] is [tex]\dfrac{1}{2}[/tex].

[tex]cos^2\theta= 1-sin^2\theta\\cos 2\theta = cos^2\theta - sin^2\theta[/tex]

Given the value of [tex]sin30^0[/tex] is [tex]\dfrac{1}{2}[/tex].

Use the relation between the sine and cosine as-

[tex]\cos^230^0=1-\sin^230^0\\=1-\dfrac{1}{4}\\=\dfrac{3}{4}\\[/tex]

Use another relation [tex]\cos 2\theta = \cos^2\theta -\sin^2\theta[/tex] as-

[tex]\cos(2\times 30^0)=\cos^2{30^0}-\sin^2{30^0}\\=\dfrac{3}{4}-\dfrac{1}{4}\\=\dfrac{1}{2}[/tex]

Hence, [tex]\cos 60^0[/tex]  is value is [tex]\dfrac{1}{2}[/tex].
