3x -(-2-4x)=
What does this equals??

Answers

Answer 1

Answer:

7x + 2

Step-by-step explanation:

Original Equation: 3x − ( −2 − 4x)

First, we distribute the negative sign:

= 3x + (−1) (−2−4x)

=3x + (−1)(−2) + (−1)(−4x)

= 3x + 2 + 4x

Using the communitive property of addition, we can write:

= 3x + 4x + 2  (Instead of 3x + 2 + 4x)

Combining like terms, we get:

= (3x + 4x) + 2

= 7x + 2

Find the total amount given the original price and tax rate. Round to the nearest cent if necessary.
$15.25,7%

Answers

Given:

Original price = $15.25

Tax rate = 7%

To find:

The total amount.

Solution:

We know that,

Total amount = Original price + Tax

According to the question,

Total amount = 15.25 + 7% of 15.25

[tex]\text{Total amount}=15.25+\dfrac{7}{100}\times 15.25[/tex]

[tex]\text{Total amount}=15.25+1.0675[/tex]

[tex]\text{Total amount}=16.3175[/tex]

Round to the nearest cent (two decimal places).

[tex]\text{Total amount}\approx 16.32[/tex]

Therefore, the total value is $16.32.

Can someone tell just the answer

Answers

Answer:

Option D is correct .

Step by step explanation:

A function is given to us and we need to find its inverse . The function is g(x) = -2x⁵ - 2.

So for finding its inverse , exachange x with y .

⇒ g(x) = -2x⁵ - 2 .

Let g(x) = y ,

⇒ y = -2x⁵ - 2 .

Replace x with y ,

⇒ x = -2y⁵ - 2

⇒ x + 2 = -2y⁵

⇒ y⁵ = x+2 / -2

⇒ y⁵ = (-1) ( x + 2) / (-1)(-2)

⇒ y⁵ = -x - 2/ 2

y = [ ( -x -2)/2 ]

Hence the inverse of the function is ,

[tex]\boxed{\red{\bf f^{-1}(x)=\sqrt[5]{\dfrac{-x-2}{2}}}}[/tex]

Hence the correct option is (D) .

What are ratio and proportion?

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

In the grids, there are 12 square box.

Let R be the red and B be the blue.

R + B = 12   ...1

R / B = 1/2  ...2

By solving equation 1 and 2, we have

R + 2R = 12

      3R = 12

        R = 4

Then  

4 + B = 12

     B = 8

Then the correct option is C.

d. (2,4), (3,4), (5,4), (6,4)​

Answers

Answer: B

Number on the left: x-value
Number on the right: y-value

If there are 2 y-values for one x-value it is NOT considered a function.

For instance in the answer:

(2,3), (2,4), (3,3), (3,4)

You can clearly see that the x-values (2 & 3) repeat more than once; therefore, it is NOT a function.

On the other hand if you have 2 DIFFERENT x-values for the same y-value it IS A FUNCTION.

For ex D: (2,4), (3,4), (5,4), (6,4)

As you can see there are 4 DIFFERENT x-values with same y-value; therefore it is A FUNCTION

To make it easier:

If x-values appear more than once = NOT A FUNCTION

If x-values appear only ONCE = FUNCTION

Remember: y-values are ALLOWED to repeat

Jiangs instrument was simple and plain, crafted from the wood of a native bamboo tree. Despite its modest appearance, the lute brought Jiang much joy. He created appealing music that lured the other villagers out to listen to him. Having an audience made Jiang feel accepted, and he quickly formed an important bond with the poor villagers.2Chao, however, didnt like Jiang. He hated Jiangs lute playing and the way the villagers admired Jiang. Although Jiang was an excellent person and a hard worker, Chao fired Jiang from his job and smashed the lute into pieces.3Miserable and brokenhearted, Jiang hung his head as he walked through the forest. Good fortune soon came to him, however, when he bumped into a compassionate old man who felt sorry for Jiangs loss.4The elderly man carved a new lute for Jiang and taught him to refine his playing technique. Soon, Jiang played better than ever before. Villagers and woodland creatures from all over came to hear him perform.Chao heard gossip of the woodland animals and decided that he wanted to capture a flaxen white rabbit with a spotted head. He promised his farm and his fortune to the son who could capture the specific rabbit for him.The sons had never laid eyes on such a rabbit before, and they didnt know where to find one, but because they knew the rabbit would bring them riches, they decided to search for it.Into the forest went the first son. He approached Jiang and described the mystical rabbit. Jiang said that if the son paid him, he would help him find the rabbit. At first, the son didnt want to pay. Then he realized that locating the rabbit would earn him his fathers fortune, so he paid Jiang the money.8Jiang began performing a song on his lute and, upon hearing him, the forest creatures gathered, including the flaxen rabbit! The farmers son seized the rabbit, but the creature struggled. Eventually, the rabbit darted back to the woods to hear Jiang play the lute, and the son couldnt recapture it. The unsuccessful son returned home, upset that he had lost his money.The other sons remained determined to catch the rabbit, so they too ventured into the woods and paid Jiang to help them attract the creature. As before, however, when Jiang played his lute, the rabbit scampered away.Chao boiled with anger and scolded his sons for losing their money and failing to catch the rabbit. He finally set out with intentions of unearthing the rabbit by himself.11As Chao entered the forest, flocks of birds and packs of creatures approached him. He trembled like a leaf in the wind.Farmer, beware! called Jiang. If I strum my lute, the creatures will attack!Chao begged Jiang to save him from this misfortune and promised to do anything.You must promise to treat people better and donate half of your possessions to the less fortunate villagers, Jiang directed.Chao quickly agreed because he was so terrified, and he followed through on his promise. Satisfied, Jiang continued to work as a shepherd and play his lute.Which statement is the best description of a theme of this story The Shepherds Lute: A Chinese Folktale?
