Answer:

This represents an absolute value graph, therefore the distance between them is  8.944272

Step-by-step explanation:

d = 8.944272

For:

(X1, Y1) = (6, 2)

(X2, Y2) = (-2, 6)

Distance Equation Solution:

d=(−2−6)2+(6−2)2−−−−−−−−−−−−−−−−√

d=(−8)2+(4)2−−−−−−−−−−√

d=64+16−−−−−−√

d=80−−√

d=8.944272

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

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.

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.

Answer:

$650.  This was the original price.

Step-by-step explanation:

Let p represent the original price.

The following expression calculates the value of p:  (1 - 0.38)p = $403.  Note that '1' indicates full price and that '0.38' indicates a 38% discount.

(1 - 0.38)p = $403 simplifies to (0.62)p; = $403.

Dividing both sides by 0.62 yields $650.  This was the original price.

Answer:

$650

Step-by-step explanation:

Line up $ with $ and % with % then cross multiply

$403 represents ........100% full price -38% discounted  = 62%

$ x amount of the original price represents .........................100%

x*62 = 403*100, cross multiply

x = (403*100)/62, divide both sides by 62

x = $650

The places where you can find state-specific information about lottery information to sell, lottery tickets, redeem winning and lottery tickets are the lottery terminal handbook, and lottery vending machine.

Lottery Terminal Handbook is a text containing information related to the lottery Terminal (Electronic Device). This text explains all the functions of the Lottery terminal, how to print the tickets, and how to redeem wining prizes.

On the other hand, a Lottery vending machine is a specialized machine for offering and selling lottery tickets. In these machines, the buyer enters money corresponding to the value of the lottery ticket, and the machine gives him scratch-off tickets or another type of ticket.

According to the above, the information related to lottery tickets can be found in a lottery terminal handbook and a lottery vending machine.

Answer:

270 is the answer if you add

Answer:

Step-by-step explanation:

P = 2L + 2W

L = 4w - 30

w = w

P = 2(4w - 30) + 2W

but  P = 240

2(4w - 30) + 2w = 240         Remove the brackets.

8w - 60 + 2w = 240             Combine

10w - 60 = 240                     Add 60

10w - 60 + 60 = 240+60      Combine

10w = 300                             Divide by 10

w = 30

L = 4w - 30

L = 4*30 - 30

L = 120 - 30

L = 90

The ODE

y''' - 7y'' + 8y' + 16y = 0

has characteristic equation

r ³ - 7r ² + 8r + 16 = 0

which can be factorized as

(r - 4)² (r + 1) = 0

Then the characteristic solution to the ODE is

y(x) = C₁ e ⁴ˣ + C₂ x e ⁴ˣ + C₃ e ⁻ˣ

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.

Step-by-step explanation:

The best way to divide fractions is to not divide them at all.

Convert both mixed numbers into improper fractions.

4 times 2 is 8

8 + 1 is 9

I have 9/2 halves. Don't forget to put the negative back in.

1 times 8 is 8

8 + 3 is 11

I have 11/8 eighths. Dont forget to put the negative back in.

You will end up with

-9/2 ÷ -11/8

Flip the second fraction and change the division sign to a multiply sign

-9/2 × 8/-11

Multiply the numerators together and the denominators together

-9 x 8 and 2 x -11

-72 / -22

Dividing a negative by a negative will give us a positive

72 / 22

Simplify by dividing the top and bottom by 2

36/11

We cannot simplify further. You can answer like this or convert back into a mixed number.
