hello I need help with graphing my functions it's y = 2x + 3 but I need to graph it

Answers

The variable x is a placeholder for a number

Let's say we replace x with 0

y = 2x+3

y = 2(0)+3

y = 0+3

y = 3

This means x = 0 and y = 3 pair up together. In short, the point (0,3) is on the line.

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

Let's repeat for x = 1

y = 2x+3

y = 2(1)+3 ... replace x with 1

y = 2+3

y = 5

So (1,5) is another point on the line

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

We can keep this process going to generate as many points as we want. But to graph a linear equation like this, we only need two points at minimum.

Graph both (0,3) and (1,5). Then draw a straight line through them both. The graph is shown below.

You are going on a field trip and need to choose where to go, The zoo charges a $100 fee plus $10 per student. The museum charges $200 plus $5 per student. How many students have to go on the trip to make the museum a better deal

Answers

Answer:

21 kids have to go on the trip to make the museum a better deal

Step-by-step explanation:

Zoo: y=10x+100

Museum: y=5x+200

10x+100=5x+200

5x=100

x=20

When 20 kids go on trip the costs will be the same. Therefore, once 21 kids go the museum will be cheaper then the zoo as it is increasing at a rate of 5 dollars

The figures below show sketches of Earl's and Dylan's flower gardens. If the perimeter of each of their gardens is the same, what is the length and width of Earl's garden?

Answers

Answer:

[tex] length = 12 ft [/tex]

[tex] width = 8 ft [/tex]

Step-by-step explanation:

Earl's garden:

[tex] length = (x + 6) ft [/tex]

[tex] width = (x + 2) ft [/tex]

[tex] perimeter = 2(length) + 2(width) [/tex]

[tex] perimeter = 2(x + 6) + 2(x + 2) [/tex]

[tex] perimeter = 2x + 12 + 2x + 4 = (4x + 16) ft [/tex]

Dylan's garden:

[tex] length = (2x - 2) ft [/tex]

[tex] width = (x + 4) ft [/tex]

[tex] perimeter = 2(length) + 2(width) [/tex]

[tex] perimeter = 2(2x - 2) + 2(x + 4) [/tex]

[tex] perimeter = 4x - 4 + 2x + 8 = (6x + 4) ft [/tex]

Generate an equation to solve for the value of x.

Since the perimeters of both gardens are the same, therefore:

[tex] 6x + 4 = 4x + 16 [/tex]

Collect like terms

[tex] 6x - 4x = - 4 + 16 [/tex]

[tex] 2x = 12 [/tex]

Divide both sides by 2

[tex] x = 6 [/tex]

Earl's garden:

[tex] length = (x + 6) ft [/tex]

Plug in the value of x

[tex] length = 6 + 6 = 12 ft [/tex]

[tex] width = (x + 2) ft = 6 + 2 = 8 ft [/tex]

Answer:

l: 12ft

w: 8ft

GEOMETRY A container company wants to make a
cylindrical cardboard container with a volume of 4752 cubic inches. The formula V = roh represents the volume of a cylinder. In this formula, V represents the volume, represents the radius of the cylinder's base, and h represents the height of the cylinder. Solve for h. What height should the company make the container if the radius of the base must be 9 inches?

Answers

You have the formula... V = pi * R^2 * h

4752 in^3 = 3.14 * 9"^2 * h (with the numbers plugged in)

4752 in^3 = 3.14 * 81"^2 * h (with the squaring math completed)

4752 in^3 = 254.14"^2 * h (with the multiplication math completed)

4752 in^3 / 254.14"^2 * h / 254.14"^2 (showing the division from both sides to get "h" alone)

18.68" = h (the answer)

I need to show my work

Thank you!!!!!!

Answers

Answer: x = 36

===============================

Work Shown:

2x+108 = 180

2x+108-108 = 180-108

2x = 72

2x/2 = 72/2

x = 36

-------

Notes:

The reason 2x and 108 add to 180 is because they form a straight angleIn step 2 above, I subtracted 108 from both sidesIn the second to last step above, I divided both sides by 2.The general steps to solving any equation is to follow PEMDAS in reverse to isolate the variable.

Given : There is a line . It is divided into two parts by another line such that it forms two angles on two sides of the angle which are 2x° and 108° .

To Find : The value of x .

Solution : Given that the two angles are 2x and 108° . So , we know that the measure of a straight line is 180° . So the sum of the two angles will be also equal to 180°. That is ;

[tex]\large\boxed{\red{\bf \angle 1 + \angle 2= 180^{\circ}}}[/tex]

Where [tex]\angle[/tex]1 and [tex]\angle[/tex]2 are two angles .

⇒ 2x° + 108° = 180° .

⇒ 2x° = 180° - 108° .

⇒2x° = 72°.

⇒ x =[tex]\sf \dfrac{72}{2}[/tex]

⇒ x = 36° .

Hence the value of x is 36° .

hey guys can you answer this one question real quick

Answers

Answer:

a. 1/5

b. (3, 3/5)

c. 1/5x = y

Step-by-step explanation:

Remember: (x, y)

0.5 = 1/2

(1/2, 1/10) = 1/10 ÷ 1/2 = 1/10 • 2 = 1/5, you can divide y/x = constant of proportionality. 1/10 ÷ 1/2.

1 2/5 = 7/5

(7, 7/5) = 7/5 ÷ 7 = 7/5 • 1/7 = 1/5, y/x = constant of proportionality. 7/5 ÷ 7.

a. 1/5 is the constant of proportionalityb. (3, 3/5) because 3/5 ÷ 3 or 3/5 • 1/3 = 1/5.c. 1/5x = y
