Answer 1

Answer:

x = [tex]\frac{9}{4}[/tex]

Step-by-step explanation:

Given

[tex]\frac{4x}{x+1}[/tex] - [tex]\frac{5}{x}[/tex] = [tex]\frac{4}{x^2+x}[/tex] ← factor denominator

[tex]\frac{4x}{x+1}[/tex] - [tex]\frac{5}{x}[/tex] = [tex]\frac{4}{x(x+1)}[/tex]

[ x ≠ 0, x ≠ - 1 as these would make the terms undefined ]

Multiply through by x(x + 1)

4x² - 5(x + 1) = 4

4x² - 5x - 4 = 4 ( subtract 4 from both sides )

4x² - 5x - 9 = 0 ← in standard form

(x + 1)(4x - 9) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

4x - 9 = 0 ⇒ 4x = 9 ⇒ x = [tex]\frac{9}{4}[/tex]

However, x ≠ - 1 for reason given above, then

solution is x = [tex]\frac{9}{4}[/tex]

Fahim is 6 feet tall. At noon, he stands with the sun behind him casting a shadow. The distance from the top of Fahim’s head to the furthest tip of the shadow is 13 feet.

A right triangle with side length 6 feet, s, and hypotenuse 13 feet.
[Not drawn to scale]

What is the length of Fahim’s shadow? Round to the nearest tenth of a foot.
7.0 feet
8.5 feet
11.5 feet
14.3 feet

Answers

Answer: 11.5 feet

Step-by-step explanation:

We should note that for a right angles triangle, the square of the hypothenuse equals to the square of the opposite side and its adjacent. This can be expressed as:

Let the length of Fahims shadow be x

hypotenuse² = opposite² + adjacent ²

13² = 6² + x²

169 = 36 + x²

x² = 169 - 36

x² = 133

x =✓133

x = 11.53

= 11.5 feet to nearest tenth

Answers

Answer:

VW = 29

Step-by-step explanation:

Perimeter of the triangle = 82

Perimeter of the triangle = 4x + (x + 3) + (3x - 1)

4x + (x + 3) + (3x - 1) = 82

4x + x + 3 + 3x - 1 = 82

8x + 2 = 82

8x = 82 - 2

8x = 80

x = 10

VW = 3x - 1

VW = 3(10) - 1

VW = 30 - 1

VW = 29

Which representations show a direct variation?

y = - x

y = 2 x + 3

Input (x) 3 6 9 12 15
Output (y) 4 8 12 16 20

Answers

Answer:

Options 1 and 3 are direct variation

Step-by-step explanation:

Direct variation is:

y = kx

Options:

1.

y = -x, k = -1, yes

2.

y = 2x + 3, not a direct variation, no

3.

Try the input/output to determine the direct variation:

4 = 3k k = 4/3

Verify the other pairs:

x = 6, y = 6(4/3) = 8x = 9, y = 9(4/3) = 12x = 12, y = 12(4/3) = 16x = 15, y = 15(4/3) = 20

This is also a direct variation

Write the an equation of a line that is perpendicular to y= 1/3x + 5 and intersects it at the y intercept

Answers

Answer:

y = -3x + 5

Step-by-step explanation:

For two lines to be perpendicular, the product of their slope must be -1.

Slope of the given line M = 1/3

Slope of the required line is m

If product is -1, then;

Mm = -1

1/3 m = -1

m = -3

SInce it intersects at the y intercept, y intercept c = 5

Get the required equation. Substitute m = -3 and c = 5 into the equation

y = mx+c

y = -3x + 5

Hence the required equation of the line is y = -3x + 5

Ben and Carson went to the movies with friends. Ben purchased 3 popcorn and 2 boxes of candy for $41. Carson purchased 1 popcorn and 2 boxes of candy for $29. How much did the popcorn cost?

Answers

Answer:

$6

Step-by-step explanation:

B- 3P+2C=$41

C-1P+2C=$29

since they both bought at least 1 popcorn and 2 candy you can just subtract 29 from 41. you get 12 which equals the other 2 popcorns that ben bought

12/2=6

since you need to find the price of 1 popcorn you have to divide 12 by 2

Lina has five more than seven times as many pictures as photo albums. If she has 75 pictures, how many photo albums does she have?

Answers

photo albums = x

pictures =75( seven times of albums +5)

so

seven times of x is 7x and +5

7x +5 = 75

7x= 75-5

x=70÷7

x =10

x = 10 = photo albums

Taylor invested $650 in an account paying an interest rate of 2.3% compounded
daily. Assuming no deposits or withdrawals are made, how long would it take, to the
nearest tenth of a year, for the value of the account to reach $880?

Answers

Answer:

Step-by-step explanation:

Given that:

Principal = $650

Interest rate, r = 2.3% = 0.023 compounded daily

Time, t it takes for final amount, A to reach $880

Using the relation :

A = P(1 + r/n)^nt

n = number of times compounded per period

Hence, n = 365

880 = 650(1 + 0.023/365)^365t

880/650 = 1.0000630^365t

1.3538461 = 1.0000630^365t

Take the log

0.1315692 = 0.0000273596 * 365t

0.1315692 = 0.0099862t

t = 0.1315692 / 0.0099862

t = 13.175101

t = 13.18 years a

4x + y = 14. 5x +2y = 19 solve the simultaneous equation

Answers

Answer:

(3, 2 )

Step-by-step explanation:

Given the 2 equations

4x + y = 14 → (1)

5x + 2y = 19 → (2)

Multiplying (1) by - 2 and adding to (2) will eliminate the y- term

- 8x - 2y = - 28 → (3)

Add (2) and (3) term by term to eliminate y

- 3x + 0 = - 9

- 3x = - 9 ( divide both sides by - 3 )

x = 3

Substitute x = 3 into either of the 2 equations and solve for y

Substituting into (1)

4(3) + y = 14

12 + y = 14 ( subtract 12 from both sides )

y = 2

solution is (3, 2 )

Step-by-step explanation:

[tex] \text{4x + y = 14 - - - - - (i)}[/tex][tex] \text{5x + 2y = 19 \: - - - - - (ii)}[/tex]

Multiply equation ( i ) by 2 & Subtract from ( ii ). The equation ( i ) now becomes 8x +2y = 28 { 2 ( 4x + y ) = 2 × 14 }. Remember that while subtracting the sign of each term of equation ( i ) changes and now , it becomes -8x-2y = -28.

[tex] \text{5x + 2y = 19}[/tex]

Step-by-step explanation:

The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the values that x cannot be and if the numerator is non-zero for these values then they are vertical asymptotes.

Answers

Given :

The scale of a model train is 1 inch to 13.5 feet.

One of the cars of the model train is 5 inches long.

To Find :

The length, in feet, of the actual car.

Solution :

It is given that scale of the model is 1 inch to 13.5 feet. It means that 1 inch in the actual scale is equal to 13.5 feet in real.

So, length of car real is :

Length = 5 × 13.5 feet

Length = 67.5 feet

Therefore, the length of the actual car is 67.5 feet.

From there, they crossed aLand bridge into Asia and Europe. The horses in Europe and Asia continued to thrive,but the horses in North America went extinct. No one is quiet sure why they died outbut scientists think it might be because of climate change or overhunting by earlyhumans.Because horses had been extinct for so long, Native Americans did not know whathorses were until they were bringed over by the Spanish. When the conquistadorsfirst came to South America, people thought that the horses were giant dogs. Later,in 1680, Pueblo Native Americans fought the Spanish and pushed him out of newMexico. Afterwards, the Pueblo were able to use and trade horses. These horsesspread up the western part of what is now the United States, changing the lives ofthe people there.The Native Americans on the western Great Plains captured and trained the Spanishhorses that were running through the Great Plains in wild herds. On horseback,Native Americans were able to move quick over long distances. This made it easier tohunt bison, trading, and expand their territory. Not only were the bison a source offood, and they could also be used to create buffalo robes. Native Americans couldtrade these robes with the white settlers for goods, like blankets and guns, Horsesalso made life easyer for women.
