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)
===========================================================
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.

A triangle with vertices at point A(-2,1), B(1,5), and C(2,3) calculate the coordinates of the mid point of AB
=======================================================
Explanation:
Add up the x coordinates of A and B
-2+1 = -1
Then cut that result in half
-1/2 = -0.5
This is the x coordinate of the midpoint.
Repeat these steps for the y coordinates: (1+5)/2 = 6/2 = 3
The midpoint of segment AB is located at (-0.5, 3)

Problem 2
x = amount of candy Ian goty = amount of candy Joe gotz = amount of candy Josh gotBased 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 JoeThe 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:
y = -4, x = 9
Step-by-step explanation:
If a line is horizontally passing through a point, then the equation of that line must be the y-value of that coordinate point. Likewise, if a line is passing vertically through a point, then the equation of that line must be the x-value of that coordinate point.
Apply the theory to this problem.
The equation for the horizontal line is y = -4
The equation for the vertical line is x = 9

Estimate the area of the irregular shape. Explain your method and show your work. Will Mark Brainliest if correct. And please Do Not Repost someone else's answers from brianly or another websites.
9514 1404 393
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.
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)
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

A Ferris wheel can accommodate 40 people in 20 minutes. How many people
could ride the ferris wheel in 3 hours? What was that rate per hour?
Answer:
360 people in 3 hours. 120 people per hour.
Step-by-step explanation:
How many times do 20 minutes go into 3 hours?
Well, 60 min. ÷ 20 min. = 3
So, 3 x 3 = 9
So 40 people went on the ride each 20 minutes. And there are (3) 20 minutes in every hour.
So 3 hours would be 9 x 40 = 360
120 people per hour because 40 x 3 = 120
and 20 minutes (3) times equals 1 hour.

(2p + 5)(p² + 3)
Step-by-step explanation:
2p³ + 5p² + 6p + 15
