4(2x−9)=4 solve for x

Answers

Answer 1

Answer: x=5

Step-by-step explanation:

Distribute the 4 to the 2 and 9 and you will get (8x-36)=4.

Then you'd add the 36 to 4 to get 40.

Lastly you'd divide 8 and 40 to get 5. Hope this helps!!!

A train traveled from one city to another city in 4 hours at a speed of 70 mph.
The retum trip was made in 5 hours. Find the speed for the return trip.

Answers

Answer:

56miles/hr

Step-by-step explanation:

Given parameters:

Time taken for the to travel  = 4hrs

Speed of the train  = 70mph

  From this data, let us find the distance of the trip;

Distance  =Speed x time

  Therefore, insert the parameters;

          Distance  = 70mph x 4hr = 280miles

Now;

  Return trip took, 5hrs,

Speed  = ?

  Speed  = [tex]\frac{distance}{time}[/tex]  

Insert the parameters and solve;

     Speed  = [tex]\frac{280}{5}[/tex]   = 56miles/hr

Mr Thompson wants to cut a 5-ft rope into a 1/4-ft sections how many 1/4 sections will he have

Answers

Answer:

20 pieces of rope

Step-by-step explanation:

Mr. Thompson has a 5-ft rope. If he cuts the rope into 1/4-ft pieces, that means for every foot, there are 4 pieces of rope. There are 5-ft of rope, so we multiply 5 and 4 to get the number of pieces of rope.

5 x 4 = 20 pieces of rope.

A farmer with 5000 feet of fencing wants to enclose a rectangular field and then divide it into two plots by adding a fence in the middle parallel to one of the sides. Using the function A(x) , analytically find the WIDTH of the field that would maximize its area. (Round your answer to the nearest whole number)

Answers

Answer:

The required width of the field that would maximize the area is = 1250  feet

Step-by-step explanation:

Given that:

The total fencing length = 5000 ft

Let consider w to be the width and L to be the length.

Then; the perimeter of the rectangular field by assuming a parallel direction is:

P = 3L + 2w

⇒ 3L + 2w = 5000

3L = 5000 - 2w

[tex]L = \dfrac{5000}{3} - \dfrac{2w}{3}[/tex]

Recall that:

The area of the rectangle = L×w

[tex]A(w) = ( \dfrac{5000}{3}-\dfrac{2}{3} ) w[/tex]

[tex]A(w) = \dfrac{5000}{3}w-\dfrac{2}{3} w^2[/tex]

Taking the differentiation of both sides with respect to t; we have:

[tex]A' (w) = \dfrac{5000}{3} - \dfrac{2}{3} ( 2 w)[/tex]

[tex]A' (w) = \dfrac{5000}{3} - \dfrac{4w}{3}[/tex]

Then; we set A'(w) to be equal to zero;

So; [tex]\dfrac{5000}{3} - \dfrac{4w}{3}=0[/tex]

5000  = 4w

w = 5000/4

w = 1250

Thus; the required width of the field that would maximize the area is = 1250  feet

Also, the length [tex]L = \dfrac{5000}{3} - \dfrac{2w}{3}[/tex] can now be :

[tex]L = \dfrac{5000}{3} - \dfrac{2(1250)}{3}[/tex]

L = (5000 -2500)/3

L = 2500/3 feet

Suppose, the farmer divides the plot parallel to the width; Then  2500/3 feet = 833.33 feet and the length L = 1250 feet.

Describe how the graph of y=2xy=2x is the SAME as the graph of y=2x-7y=2x−7.



Select all statements that are true.





They both have a slope of 2.


They cross the x-axis at the same point.


They are parallel to each other.


They have the same slope.


They are in the same location.


They cross the y-axis at the same point.

Answers

Answer:

-They both have a slope of 2.

-They are parallel to each other.

-They have the same slope.

Step-by-step explanation:

The 2 equations are;

y = 2x and y = 2x - 7

Now, from slope intercept equation,

y = mx + c

Where m is slope and c is the intercept on the y-axis

From the 2 equations y = 2x and y = 2x - 7, Comparing with y = mx + c, we can see they both have a slope of 2.

For 2 lines to have same slope, it means that they are parallel and have different y-intercepts.

They should cross the x-axis when y = 0.

But at x = 0,we have;

y = 2x = 0. And x = 0

Also,for y = 2x - 7 is y = 2x - 7 = 0

2x = 7 and x = 7/2.

Thus,they don't cross the x - axis at the same point

Looking at the options, we can see that there are 3 correct ones from what we've described above namely;

-They both have a slope of 2.

-They are parallel to each other.

-They have the same slope.

BRAINLIEST!!!!!!!!!!!!!!The Online Child Parents should seriously think about the online life of their children. "Online life" refers to the activities people are involved in while using the Internet. Today's teenagers have grown up with technology and the Internet. They are becoming more knowledgeable about technology, sometimes more so than their parents. These days, teenagers spend a lot of their time on the Internet using social networking sites. Other times, teenagers enjoy spending time with their school friends or playing sports. Social networking sites provide the perfect place for teenagers to exercise their freedom. In addition, these teenagers also find a venue to express themselves openly with their online friends. They post pictures of themselves and share thoughts for the whole world to see. The problem is that the teenagers are not always aware that their images and words on the Internet are permanent. Teenagers may not be aware that people often use fake identities on the Internet and give false information. In addition, problems with "friends" on the Internet can have real-life consequences. And just like a real child, the online child needs the parents to tell him or her how the world (of the Internet) works. The teenagers need to learn critical-thinking skills applicable to real life and Internet life. While educating their children on the risks of the Internet, parents should also demonstrate trust and allow their children enough space to learn on their own. For example, parents can let their children know that they will be making frequent checkups on their children's social networking page. That way, children can learn to practice caution when they post content on the Internet, while still retaining a feeling of independence. Parents can take the check-up time to teach their children about safe online habits.Which sentence could be added to the end of the introduction to strengthen it? A.
