What is 3(2x-4) + 2x + 5

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 :)

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:

x=4

Step-by-step explanation:

1. Add like terms: 5x+7=27

2. Use the subtraction property on both sides to get rid of 7: 5x=20

3. Divide 5 on both sides to get x by itself: x=4

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

Explanation:

The mean is found by adding up all of the values and dividing by n, where n is the number of values in the set.

In this case, we have n = 7 values here. We count (x+1) as well since x is a placeholder for a number, which makes (x+1) also a placeholder in a sense.

As for what replaces x, we're not sure yet but we can use algebra to solve.

Lets add up all of the values given except for the "5" at the end. That 5 is the mean which is not part of the data set.

Adding up those values mentioned gives:

4+6+4+7+(x+1)+8+2 = x+32

Then divide this over n = 7 to get the mean 5

(x+32)/n = mean

(x+32)/7 = 5

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

Let's isolate x

(x+32)/7 = 5

x+32 = 7*5

x+32 = 35

x = 35-32

x = 3

If x = 3, then x+1 = 3+1 = 4

So the (x+1) is being a placeholder for the number 4.

In other words, we'll replace the (x+1) with 4.

The data set of

4,6,4,7,(x+1),8,2

updates to

4,6,4,7,4,8,2

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

We'll get to the median in a moment, but first we need to check if we have the correct replacement for (x+1)

Add up the values in the set {4,6,4,7,4,8,2}

Doing so leads to: 4+6+4+7+4+8+2 = 35

Then divide by n = 7 to compute the mean: 35/n = 35/7 = 5

We get the mean is 5 which matches with the instructions. So we have the correct replacement for the (x+1). We can now find the median.

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

To find the median of any data set, we need to make sure the numbers are in order from smallest to largest.

Right now {4,6,4,7,4,8,2} is not sorted, but we can sort the items to get {2,4,4,4,6,7,8}

The median is at the exact middle. In this set, the median is that third copy of '4'. Note how "2,4,4" is to the left of the median while "6,7,8" is to the right of the median. There is the same number of values on either side of the median to show things are balanced and we are at the center point.

As an alternative, you can cross off each pair of outer values one at a time until you steadily arrive at the midpoint, which again is that third copy of '4'.

So that's why the median is 4.

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

Answer:

two ways in which the relationship negatively

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)

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!

You won't get everything perfect the first time you try but the more you practice the more comfortable you are with these problems, Hope my explanation helped!

You don't have to pay rent every month

Step-by-step explanation:

The advantage of purchasing and owning a home are:

- Building equity,

- Stability

- Investment

- 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.

We have,

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:

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:

one plane can be drawn so it contains all three points for this question.

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.
