What is the solution of the following system?
-2x - y = 1
-4x - 2y = -1
A. infinitely many solutions
B. no solutions
C. (3, 8)
D. (–3, –8)

Answers

Answer:  B) no solutions

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

Explanation:

Let's isolate the variable y in the first equation

-2x - y = 1

-2x = 1 + y

1+y = -2x

y = -2x-1

Then we'll plug this into the second equation

-4x - 2y = -1

-4x - 2(-2x-1) = -1

-4x + 4x + 2 = -1

0x + 2 = -1

0 + 2 = -1

2 = -1

We run into a contradiction. No matter what x value we pick, the last equation will never be true. This leads to a domino effect to cause the first set of original equations to never be true when considered as a system.

Therefore, this system is inconsistent. There are no solutions. These two lines graph out parallel lines that never intersect.

Problem 2

x = amount of candy Ian goty = amount of candy Joe gotz = amount of candy Josh got

Based on those variables, we can form these equations

x+y+z = 75 since all three got 75 totalx = 3y+6 due to "Ian collected six more than three times the amount Joe got"z = y-11, since Josh collected 11 pieces less compared to Joe

The system of equations is

[tex]\begin{cases}x+y+z = 75\\x = 3y+6\\z = y-11\\\end{cases}[/tex]

Let's start with the first equation. Then apply substitution like so

x+y+z = 75  

3y+6+y+z = 75 ... plug in x = 3y+6

4y+6+z = 75

4y+6+y-11 = 75 ... plug in z = y-11

5y-5 = 75

5y = 75+5

5y = 80

y = 80/5

y = 16 = amount of candy Joe collected

z = y-11 = 16-11 = 5 = amount Josh collected

x = 3y+6 = 3*16+6 = 54 = amount Ian collected

Answer: 54 pieces of candy

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

Problem 3

x = number of pounds of candy that sells for $1.49 a pound

1.49x = cost of buying those x pounds of candy at that unit price

4.50*5 = 22.50 = cost of buying 5 pounds at $4.50 per pound

1.49x+22.50 = total cost

x+5 = total weight in pounds

(total cost)/(total weight) = final cost per pound

(1.49x+22.50)/(x+5) = final cost per pound

(1.49x+22.50)/(x+5) = 3.64

1.49x+22.50 = 3.64(x+5)

1.49x+22.50 = 3.64x+18.20

22.50-18.20 = 3.64x-1.49x

4.30 = 2.15x

2.15x = 4.30

x = (4.30)/(2.15)

x = 2

Answer:  2 pounds

Problem 5

g = number of ghosts

w = number of witches

s = number of scarecrows

g+w+s = 22 = total number of items

w = g+1 since there's one more witch compared to ghosts

s = w-7 since there's 7 less scarecrows than witches

The system we need to solve is

[tex]\begin{cases}g+w+s = 22\\w = g+1\\s = w-7\\\end{cases}[/tex]

We'll use substitution here as well

g+w+s = 22

g+w+w-7 = 22 ... plug in s = w-7

g+2w-7 = 22

g+2(g+1)-7 = 22 ... plug in w = g+1

g+2g+2-7 = 22

3g-5 = 22

3g = 22+5

3g = 27

g = 27/3

g = 9, there are 9 ghosts

w = g+1 = 9+1 = 10 witches

s = w-7 = 10-7 = 3 scarecrows

Answers:

10 witches and 3 scarecrows

Answer:

  29 square units

Step-by-step explanation:

One estimate could be obtained by approximating the shape by a polygon with vertices at ...

  (-3, 3), (2, 2), (2, -2), (-3, -4), (-4, -3), (-3, -1)

The idea is to try to have about as much area outside this boundary as inside with reference to the curve shown.

This can be subdivided into a trapezoid with the first four vertices shown, and a triangle with the last three vertices shown. The respective areas are ...

  trapezoid area = 1/2(b1 +b2)h = 1/2(7+4)(5) = 27.5

  triangle area = 1/2bh = 1/2(3)(1) = 1.5

Then the total estimated area is about 27.5 +1.5 = 29 square units.

Find the coordinates of the point.

The point is seven units to the left of the y-axis and two units below the x-axis.

Answers

Answer:

(-7, -2)

Step-by-step explanation:

If you look on a graph and travel 7 units to the left of the y axis, you are traveling in the x direction (along the x axis). Since you are 7 units to the left, you are at -7 in the x direction.

If you look on a graph and travel 2 units down below the x axis, you are traveling in the y direction (along the y axis). Since you are 2 units down, you are at -2 in the y direction.

Coordinates are listed in (x,y) format, so it would be (-7, -2)

Company X has the following capital structure, which it considers to be optimal:

Debt =33%, Preferred stock = 28%, Common equity = 39%

Company X’s tax rate is 25% and investors expect earnings and dividends to grow at a constant rate of 6.5% in the future. Company X is expected to pay a dividend of $4.40 per share next year, and its stock currently sells at a price of $55 per share.

Company X can obtain new capital in the following ways:

Preferred: New preferred stock with a dividend of $13 can be sold to the public at a price of $109 per share.
Debt: Debt can be sold at an interest rate of 11%.

Calculate the following:

a. Cost of Common equity?

b. Cost of Preferred Equity?

c. Cost of debt?

d. Weighted Average Cost of Capital (WACC)

Answers

The computations of Company X's Capital Structure is as follows:

a. Cost of Common equity = 7.48% ($4.114/$55 x 100)

b. Cost of Preferred stock = 11.93% ($13/$109 x 100)

c. After-tax cost of debt = 8.25% (11% x 1 - 0.25)

d. Weighted Average Cost of Capital (WACC):

= (39% x 7.48% + 28% x 11.93% + 33% x 8.25%)

= (2.92% + 3.34% + 2.72%)

= 8.98%

= 9%

Data and Calculations:

Capital Structure Weights:

Weight of Debt =33%

Weight of Preferred stock = 28%

Weight of Common equity = 39%

Corporate tax rate = 25%

Earnings growth = 6.5%

Expected dividend per share next year = $4.40

Dividend per share for the current year = $4.114 ($4.40 x 93.5%)

Current common stock price per share = $55

What do you think the Harlem Cultural Festival meant to the Black community in 1969 and why? Cite evidence from the article below and add your own ideas in your response.The Chambers Brothers quintet launched into "Uptown (to Harlem)" on June 29, 1969. By then, 50,000 people had already made their way to the New York City neighborhood. For six Sundays, in fact, crowds at the Harlem Cultural Festival listened and danced to a who's who of Black music greats. It was a jubilant celebration of Black lives at the end of a turbulent decade."That concert was like a rose coming through cement," reflected one attendee.The 1960s had witnessed hard-fought wins for Black Americans. The civil rights movement had led to federal laws banning segregation. Another protected Black voting rights. Black cultural figures like writer James Baldwin and boxer Muhammad Ali had risen to national prominence. By 1969, the mottos "Black Pride," "Black Power," and "Black is Beautiful" were gaining momentum.The "cement" of racism, discrimination, and poverty continued to weigh heavily on the Black community, however. And the assassinations of Malcolm X in 1965 and Dr. Martin Luther King, Jr. three years later landed like cinder blocks. Dr. King's murder had triggered civil unrest in more than 100 U.S. cities. New York City was among them. It was against this backdrop that city leaders supported the 1969 Harlem Cultural Festival. Harlem has a long history as a center of Black culture. It was an ideal setting for a symbolic rose to bloom.The result was a series of free concerts in Mount Morris Park. They featured music for everyonegospel, jazz, blues, soul, funk, and rock. The pop group The 5th Dimension headlined the opening concert. The second Sunday was a gospel showcase starring the "Queen of Gospel Song," Mahalia Jackson. And the big names kept coming: Stevie Wonder, Gladys Knight and the Pips, Nina Simone, blues guitar master B.B. King, and more. There were also speeches by civil rights leaders. They called for Black unity and political action.Over the course of the festival, some 300,000 people packed the park. In sunshine and rain, people stood shoulder to shoulder. Parents wearing dashikis brought babies. Kids climbed trees for better views. Teens danced wherever they found room.The performers themselves knew they were part of something special. "I didn't expect a crowd like that," singer Gladys Knight recalled years later. "Something very important was happening. It wasn't just about the music."When it was over, though, the Harlem Cultural Festival faded from memory. TV producer Hal Tulchin had filmed the concerts. But when he contacted TV networks, the response was indifferent. Hours of footage sat in a basement for nearly 50 years. It was almost discarded. Then, musician Ahmir "Questlove" Thompson learned of the footage and turned it into an award-winning documentary. Summer of Soul was released in 2021.Now the festival has new life. Dorinda Drake, for one, is thankful. The concerts thrilled her when she was 18. Today, she remembers the overwhelming joy of the audience. "All the happy faces, the familiesthe crowds were just so happy," she told National Geographic. "And to see a bunch of happy Black faces like thatit was a beautiful thing."
