x-10<-26
help lololololol

Answers

Hope this will help you!! <3

Answer:

Step-by-step explanation:

1) -90 ≥ 18x

Divide both sides by 18

-90/18 ≥ 18x/18

-5 ≥ x

2)x/3 > -8

Multiply by 3,

3*(x/3) > -8*3

x> -24

3)x - 10 < -26

Add 10 to both sides

x < -26 +10

x < -16

4) 19 -x ≥ 21

Subtract 19 from both sides,

-x ≥ 21 - 19

-x ≥ 2

Divide both sides by (-1)

x < -2

How much greater is the surface area of the rectangular prism than the surface area of the cube?

Answer:

Step 1 :Equation at the end of step 1

((81•(x4))-((72•(x2))•(y2)))+24y4

Step 2 :

Equation at the end of step 2 :

((81 • (x4)) - ((23•32x2) • y2)) + 24y4

Step 3 :

Equation at the end of step 3 :

(34x4 - (23•32x2y2)) + 24y4

Step 4 :Trying to factor a multi variable polynomial

4.1 Factoring 81x4 - 72x2y2 + 16y4

Try to factor this multi-variable trinomial using trial and error

Found a factorization : (9x2 - 4y2)•(9x2 - 4y2)

Detecting a perfect square :

4.2 81x4 -72x2y2 +16y4 is a perfect square

It factors into (9x2-4y2)•(9x2-4y2)

which is another way of writing (9x2-4y2)2

How to recognize a perfect square trinomial:

• It has three terms

• Two of its terms are perfect squares themselves

• The remaining term is twice the product of the square roots of the other two terms

Trying to factor as a Difference of Squares:

4.3 Factoring: 9x2-4y2

Put the exponent aside, try to factor 9x2-4y2

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 9 is the square of 3

Check : 4 is the square of 2

Check : x2 is the square of x1

Check : y2 is the square of y1

Factorization is : (3x + 2y) • (3x - 2y)

Raise to the exponent which was put aside

Factorization becomes : (3x + 2y)2 • (3x - 2y)2

Final result :

(3x + 2y)2 • (3x - 2y)2

Step-by-step explanation:

Answer:

81x+16y

should be the correct one

Answers

Answer:

-2k + 6

Step-by-step explanation:

We start out with the expression -2k - (-5) + 1. We should first distribute the negative outside of (-5), which gets us to 5: -2k + 5 + 1. Now, we can combine like terms with 5 and 1 to get 6, giving us a final answer of -2k + 6. We can't simplify any further since there aren't any like terms.

1. given w(x)=4x
a. graph r(x)=4 x w(x). then complete the table of corresponding points on r (x). How do you graph this?

Answers

Answer:

Step-by-step explanation:

a). When graph w(x) is transformed to r(x) = 4 × w(x), graph of w(x) is vertically stretched by a scale factor of 4.

Table for the corresponding points will be,

x w(x) r(x)

0 0 0×4 = 0

15 60 60×4 = 240

30 120 120×4 = 480

45 180 180×4 = 720

b). As discussed in part (a), graph of w(x) will be vertically stretched by a scale factor of 4 to produce the graph of r(x).

c). Since, w(x) = 4x

and r(x) = 4[w(x)]

r(x) = 4(4x) = 16x

r(x) = 16x

Aman bought a computer for 24000 and its accessories pack worth for 1750. He sold it all for *26780. Find his gain and gain per cent.

Answers

Answer:

Step-by-step explanation:

Gain percentage = 1030/25750 x 100 = 4%

Answer:

$1,030, 4%

Step-by-step explanation:

Aman spent $25,750 on a computer and accessory packs (totally worth it). He sold it for $26,780. So let's say Aman is at 0 before he bought this. He spent $25,750, so we subtract that from 0 to get -25,750. Then he sells it all for $26,780 (again totally worth it for the person buying). So we add 26,780 to the total.

-25,750 + 26,780 = 1,030

So Aman made a profit of $1,030 (now he can buy a REASONABLY priced MacBook Air or something)

So to find the percentage that he gained, we divide 1,030 by his original spending price, namely 25,750

1,030/25,750 = 0.04

Convert that to percentage form, you get 4%

Also, it's questions like this that make me question whether the people who write these questions into the textbooks should be talked to lol.

D. if the family wants to lay carpet in the living room and carpeting cost $1.25 per square foot, how much will carpet cost

Answers

Answer:

See below

Step-by-step explanation:

According to dimensions of the garage, the scale is:

1 in : 20 ft, as the width of the garage is 20 ft and on paper is 1 in

Living room

Dimensions on paper:

2 in x 1 1/4 in

Actual dimensions:

2*20 ft = 40 ft and1 1/4 * 20 ft = 25 ft

The area of the living room:

A = lw = 25*40 = 1000 ft²

Cost of carpet:

1000*$1.25 = $1250

Length

20(2)=40ft

Width

1.25(20)25ft

Area

how to find root hair

Answers

I'll proceed by evaluating total length and surface area by scanned images. For measurements, I suggest to use winrhizo or any similar software. In this case the most important thing to think about is to use the appropiate acquisition parameters, I mean, to set a good resolution during scanning. Pixels of the aquired image should be smaller than root hairs diameter. Therefore, let me try to suggest you a good acquisition resolution. Making a quick research, it seems that hair root diameters range between 0,012 and 0,017 mm, so I suggest a resolution that will give a pixel dimension of 0,002 mm. Root hair diameters should be composed by 6-8 pixels, that is enough for winrhizo measurements. Resolution is measured in dpi, so in "dots/pixel per inch". A inch is 25,4 mm. We need pixels with a diameter of 0,002 mm, so in 25,4 mm we found 12700 pixels. That means 12700 dpi. It's a very high resolution, you need a good scanner and much space in your computer.

Jim is a 21-year-old male in his third year of college, and he has decided that it is time for him to get back in shape. During high school, Jim was active in sports and followed a healthy diet, but the demands of work and study, and his social life have taken their toll on Jims health. He weighs more, doesnt exercise, drinks on the weekends, eats a lot of fast foods like hamburgers and French fries, donuts, and pizzas, and he began smoking about three years ago. Due to the pressures of study and work, Jim also gets very little sleep.Since Jim has decided to get back in shape, his first step was to get a checkup in the schools health clinic. During the physical exam, the nurse measured Jims height, weight, and blood pressure. Jim is 1.8 meters tall, weighs 90 kilos, and his blood pressure is 132/84 mmHg. Jim was not concerned until his doctor informed him that high blood pressure or hypertension is a blood pressure of 140/90 mmHg or higher. Jims blood pressure value qualified him as prehypertensive, which means that he has an increased risk of developing hypertension in the future. Jim told his doctor that several family members on his dads side of the family have hypertension, and some had died before the age of 50 of heart attacks.Hypertension is a disease of the cardiovascular system that is correlated with an increase in heart disease, stroke, and kidney disease and vision problems. Most people consider hypertension to be a disease of middle age, but almost one in five young adults are affected as well, making it one of the major health risks facing young adults.After speaking with his doctor, Jim realized that he knew very little about how his body worked, and had never considered how his life style choices influenced his health. He was determined to learn more about how his body functions, especially the cardiovascular system. He also wants to work on making positive changes in his lifestyle, starting with changes in his diet. He needs your help with his new objectives.1. Identify and describe at least five risk factors that the patient has for developing disorders of the cardiovascular system. Justify your answer.2. Explain the function of the cardiovascular system by describing the cardiac cycle and how it relates to blood pressure, how blood flows through the heart and the blood vessels, capillary exchange, and the function of all the components of blood (plasma, red blood cells, white blood cells, and platelets). Use illustrations to demonstrate functions.3. Explain the function of the respiratory system and how it works with the cardiovascular system to achieve respiration. Describe ventilation, external and internal respiration. Include illustrations of each process.4. Explain the functions of the urinary system by describing the function of each organ, describe the nephron and its blood supply, and finally describe the process of urine formation using examples of substances that are filtered, reabsorbed and excreted.
