Given:

The graph of an inequality.

To find:

The inequality for the given graph.

Solution:

From the given graph it is clear that the boundary line passes through the points (6,0) and (0,-4). So, the equation of the line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-0=\dfrac{-4-0}{0-6}(x-6)[/tex]

[tex]y=\dfrac{-4}{-6}(x-6)[/tex]

[tex]y=\dfrac{2}{3}(x-6)[/tex]

[tex]y=\dfrac{2}{3}x-4[/tex]

The area under the boundary line is shaded and boundary line is a dotted line it means the points on the line are not included in the solution set. So, the inequality sing must be <.

[tex]y<\dfrac{2}{3}x-4[/tex]

Therefore, the required inequality for the given graph is [tex]y<\dfrac{2}{3}x-4[/tex].

Answer:on all of them?

Step-by-step explanation:

Answer:

a.

Let x be the number of square yards of carpeting for which the total cost charged by the two companies will be the same.

We have an expression for the total cost of Country Carpets:

($22/ 1 yd^2)* (x yd^2) + $100

= $22*x+ $100

or 22x+ 100

We also have another expression for the total cost of City Carpets:

($25/ 1 yd^2)* (x yd^2)+ $70

= $25*x+ $70

or 25x+ 70

Now set the two expressions to be equal:

22x+ 100= 25x+ 70

⇒ 100- 70= 25x -22x

⇒ 30= 3x

⇒ 30/3= x

⇒ 10= x

The final answer for a is 10 square yards of carpeting~

b.

Let's assume that Mr. Shu wants to install carpeting for 1 square yard.

Country Carpets: $22*1+ $100= $122

City Carpets: $25*1+ $70= $95

Therefore, Mr. Shu will be likely to choose City Carpets if he wants to install carpeting for 1 square yard.

Now let's try x=11 (square yard):

Country Carpets= $22*11+ $100= $342

City Carpets= $25*11+ $70= $345

Therefore, Mr. Shu will be likely to choose Country Carpets if he wants to install carpeting for 11 square yard.

If you paid really close attention, you would notice that the price of City Carpets will be cheaper than the other when x is >0 and <10. At x=10, the price is equal. When x is >10, the price of Country Carpets will be cheaper than the other one.

So it depends:

If x were >0 and <10, Mr. Shu would be likely to choose City Carpets.

If x were 10, Mr. Shu could choose either Country Carpets or City Carpets.

If x were > 10, Mr. Shu would be likely to choose Country Carpets.

Hope this helps~

Answer:

x < 4

Step-by-step explanation:

Given the inequality :

- 20 > - 4(2x - 3)

Open the bracket

-20 > - 8x + 12

Collect like terms

-20 - 12 > - 8x

-32 > - 8x

Divide both sides by - 8

4 > x

x < 4

The advantage of purchasing and owning a home are:

- Building equity,

- Stability

- Pride of ownership

- Tax benefits

A home is a place where a person or a family lives, typically a house or an apartment.

It is a place of residence and refuge, where individuals or families can feel secure and comfortable.

There are several advantages of purchasing and owning a home, including:

Building equity: When you make mortgage payments, you are building equity in your home. This means that over time, you own more and more of your home and may be able to use the equity to your advantage.

Stability: Owning a home provides a stable living situation since you are not subject to rent increases or the possibility of eviction.

Investment: A home can be a good long-term investment as it generally appreciates in value over time. This means that if you sell your home in the future, you may be able to sell it for more than you paid for it.

Pride of ownership: Owning a home can give you a sense of pride and accomplishment, and you have the freedom to make changes and improvements to the property as you see fit.

Tax benefits: Homeowners may be able to deduct mortgage interest and property taxes on their income tax returns, which can result in significant savings.

Thus,

Several advantages of purchasing and owning a home are given above.

Answer:

3000.24

Step-by-step explanation:

We know that every 18 min, the colony grows 1000, so to make it easy, the way i do it is that i find out how much  it grows per min

1000 / 18 = 55.56

Then, to find out how big it will be in 54 min, we just multiply

55.56 x 54 = 3000.24

So that will be the size of the colony in 54 min. I hope this helps :)

is the answer

The image of the point (9,7) after a rotation of 180 counterclockwise about the origin is at (-9, -7)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.

Rotation of a point A(x, y) 180 counterclockwise about the origin produces an image at A'(-x, -y).

Hence, the image of the point (9,7) after a rotation of 180 counterclockwise about the origin is at (-9, -7)

Answer:

the Torah plays a big part in the lives of Jews today as it is believed to be the word of God. All Jews use the Torah to help guide them in their lives, but some Jews use the Torah more strictly than others. For example, some Orthodox Jews believe that it is important to follow every single rule in the Torah. However, Reform Jews tend to follow the rules they feel are most important and disregard some rules they see as outdated.

The significance of the Torah is seen in many ways:

It is read aloud weekly at the synagogue. It takes a year to recite the whole Torah.

The festival of Shavout celebrates God’s revelation of the Torah to Moses.

The commandments in the Torah shape the way that Jews live their lives today.

Answer:

Step-by-step explanation:

The area of a triangle is

A=bh/2 where b=base and h=height. So we first have to solve for h

8^2+h^2=12^2

h^2=12^2-8^2

h^2=144-64

h^2=80

h=(80)^(1/2), now we can find the area

A=8(80^(1/2))/2

A=4(80^(1/2)

A=35.78cm

Answer:

Para dividir un número decimal como 0.1 en 10 se debe adicionar un 0 del lado derecho del punto, es decir, del lado de los decimales.

Step-by-step explanation:

Dado que, si para dividir un número por 10 le debo suprimir a ese número la última cifra, como por ejemplo 120/10 es igual a 12, o 122/10 es igual 12 y me sobran 2, para dividir un número decimal como 0.1 en 10 se debe adicionar un 0 del lado derecho del punto, es decir, del lado de los decimales. Esto se comprueba al realizar dicha división:

0.1 / 10 = 0.01

0.01 / 10 = 0.001

This is a relatively complex problem and it took me a good 20 minutes to solve, I included a sketch I made myself while im solving this problem hope it helps with the explanation. (the dotted lines are my drawings, also I labeled the points just look at my graph)

Now to find <x, we can use the exterior angles theorem a couple of times.

<x=<p+<AGE

<x=30 degrees + <AGE

Now use the theorem again to find <AGE

<AGE=<q+<BIG

Now use substitution for <q and for <AGE

<x=30 degrees+60 degrees+ <BIG

We put this to the side for now and try solve for <CHD which is not very difficult

<CHD=180-45-20=115

We can also clearly figure out <HFI using vertical angles theorem.

<HFI=<Y

Because they all form a triangle we can conclude that <y+<BIG=180 degrees-<FHI= 180-115=65 degrees

substitution again

<x+<y=30+60+<BIG+<HFI (remember <HFI = <y vertical angles theorem)

<x+<y=30+60+65 (remember how we did before these 2 angles adds up to 65?)

<x+<y=155 degrees

Now please don't hate me on this, I'm sure there is more efficient ways to explain this problem, this is just my way from trial and error.

Tip for next time you are stuck on a geometry problem, don't be afraid to draw the graph again on paper and add lines to it!

Answer:

275$

Step-by-step explanation:

Answer: There were 40 euros in the drawer at the beginning.

Step-by-step explanation:

When we subtract 6 from 16, we get 10 more ice-creams were sold.

Similarly, we subtract 70 from 120, we get 50 euros was the total selling price of 10 ice-creams.

i.e. Selling price of 1 ice-cream = (50)÷10 =5 euros

Selling price of 6 ice-creams = 6 x 5 = 30 euros

Money in the drawer at the beginning = 70-30 = 40 euros

Hence, there were 40 euros in the drawer at the beginning.
