Answer 2

Answer:

-4 + 2  = -2      and -4 + (-2) = -6

Step-by-step explanation:

-4 + 2  = -2  

On the number line,start at zero

Do 4 jumps to the left (you are at -4)

Then do 2 jumps to the right You are at -2

-4 + (-2) = -6

On the number line,start at zero

The trail starts at P(−7, 6) and goes to Q(4, 6). It goes from Q to R(4, −6) and then to S(6, −6). What is the total length (in units) of the biking trail?

Answers

We know, distance between two points A( p,q) and B(r,s) is given by :

[tex]AB=\sqrt{(p-r)^2+(q-s)^2}[/tex]

So, distance between P an Q is :

[tex]PQ=\sqrt{(-7-4)^2+(6-6)^2}\\\\PQ=11\ units[/tex]

Distance between Q and R is :

[tex]QR=\sqrt{(4-4)^2+(6-(-6))^2}\\\\QR=12\ units[/tex]

Distance between R and S is :

[tex]RS=\sqrt{(4-6)^2+(-6-(-6))^2}\\\\RS=\sqrt{4}\\\\RS = 2\ units[/tex]

Therefore, total distance is 11 + 12 + 2 = 25 units.

Hence, this is the required solution.

how do you tell if a domain is continuous or discrete on a table not a graph •~•​

Answers

Step-by-step explanation:

gegsbdqneyqillzfjmtucznYEmdnfhhthtej62wrr334tyyytyyttffgfrwgeyeyiqlstl7o4a1‍‍

9514 1404 393

Answer:

  The domain is always discrete when it is found from a table.

Step-by-step explanation:

A table necessarily lists a finite number of discrete points. The domain, as found from a table, is always discrete.

__

If the table is said to be a representation of a continuous function, then the domain of that continuous function will be continuous.

Your question seems to have to do with a table alone, not a table and an equation, or a table and a graph. A table (of points) alone cannot express a continuous domain.

__

Additional comments

One can conceive of tables that would have continuous domains, as, for example, a table with entries ...

  (x, y) = (0 ≤ x < 3, 3x+2), (3 ≤ x < 6, 4x-1), ...

Such a table is not a list of points, but is a piecewise function definition. We presume this is not what you're concerned with.

C. blackmail her, when she DOES get it

♡ The Answer ♡

- None of the Above!

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

♡ The Explanation/Step-By-Step ♡

- A would not be a very good idea, running away from home can get you in trouble either from your parents/family/guardians, or police/fire department, that would most likely upset your mother more and could cause some issues. B wouldn't be good because soon enough she will most likely find out, breaking somebody's phone can be a bad idea too, if they're in danger they won't be able to call anybody or ask for any help. Including something important could be saved there, not to mention phones are very expensive and it could be devastating.

C isn't much of a better idea either, blackmailing somebody isn't something to be proud of and if anything, is very risky. Blackmailing is demanding money from somebody in return for not revealing compromising info about the person you're threatening. This may only be reputation ruining, but not to mention if the police/fire department find out you're threatening somebody for money you could most likely get arrested.

boris's super metal detector not only helped him win the science fair but also helped him find $6.20 in nickels and dimes yesterday morning. If boris found 14 more dimes than nickels, how many nickels did he find

Answers

Answer:

32 Nickels

Step-by-step explanation:

Given

Coins: Nickels (N) and Dimes (D)

$0.05 = 1 nickel and $0.10 = 1 dime

So, the amount implies:

[tex]0.05N + 0.10D = 6.20[/tex]

The number of coin implies:

[tex]D = 14 + N[/tex]

Required

Determine the number of nickels found

Substitute 14 + N for D in [tex]0.05N + 0.10D = 6.20[/tex]

[tex]0.05N + 0.10(14 + N) = 6.20[/tex]

[tex]0.05N + 1.4 + 0.10N = 6.20[/tex]

Collect Like Terms

[tex]0.05N + 0.10N = 6.20 - 1.4[/tex]

[tex]0.15N = 4.8[/tex]

Solve for N

[tex]N = 4.8/0.15[/tex]

[tex]N = 32[/tex]

Hence, he found 32 nickels

Courtney walked from her house to the beach at a constant speed of 444 kilometers per hour, and then walked from the beach to the park at a constant speed of 555 kilometers per hour. The entire walk took 222 hours and the total distance Courtney walked was 888 kilometers.

Answers

Answer:

I suppose that each number is repeated 3 times, the actual question is:

Courtney walked from her house to the beach at a constant speed of 4 kilometers per hour, and then walked from the beach to the park at a constant speed of 5 kilometers per hour. The entire walk took 2 hours and the total distance Courtney walked was 8 kilometers.

Now, remember the relation:

Distance = Speed*Time

Let's define:

D1 = distance between Courtney's house and the beach.

D2 = distance between the beach and the park.

T1 = time that it took the first walk.

T2 = time that it took the second walk.

We know that the total distance Courtney walked is 8km, then:

D1 + D2 = 8km.

And we also know that the entire walk took 2 hours, then:

T1 + T2 = 2h.

We also have the equations:

D1 = 4km/h*T1

D2 = 5km/h*T2.

Then we have a system of equations:

D1 + D2 = 8km

T1 + T2 = 2h

D1 = 4km/h*T1

D2 = 5km/h*T2.

To solve this, first let's replace equations 3 and 4 in the first equation:

4km/h*T1 + 5km/h*T2 = 8km

Now we have only two equations left:

4km/h*T1 + 5km/h*T2 = 8km

T1 + T2 = 2h

Now we can isolate one of the variables in the second equation and then replace it in the first equation, i will isolate T1:

T1 = 2h - T2.

Replacing this in the first equation gives:

4km/h*(2h - T2) + 5km/h*T2 = 8km

Now let's solve this for T2.

8km - 4km/h*T2 + 5km/h*T2 =  8km

8km + 1km/h*T2 = 8km

1km/h*T2 = 0

from this, we have T2 = 0

This would mean that T1 = 2h.

Then:

D1 = 4km/h*2h = 8km.

T2 = 0

D2 = 5km/h*0 = 0.

This happens because the numbers in the problem were not well thought.

You can see that when she spends the 2 hours walking at the smaller speed, she already reaches the total distance, then if she walked any amount of time at the larger speed, the total distance would be more than 8km.

x + y = 4

x − y = 6

Answers

Answer:

x=5 , y= -1

Step-by-step explanation:

You can see that one of the y's is negative while the other is positive, so you can add them together.

Now, negative 1 + positive 1 = 0, so the y's cancel out leaving only the x's.

Remember you can't add one part without adding the other so x+x = 2x, and 4+6=10. This makes the final equation 2x=10.

You can simplify that into x=5. This gives you the answer for x

Then substitute x=5 into any of the two equations (doesn't matter) I'll use the first one. So if you substitute it you get 5+y=4.

Simplified, y= -1

Therefore, x= 5 and y=-1

patricia wants to have her living room carpet cleaned she found three different companies that would clean the carpet for $198 the companies are each offering discounts on their carpet cleaning services

Answers

Answer:

company 1 final price: $148.5

company 2 final price: $168

company 3 final price: $132

thus, the best choice is company 3 because it costs the least and all services are the same

Step-by-step explanation:

company 1 is offering 25% off the price of their service

company 2 is offering $30 off the price of their service

company 3 is offering a 1/3 discount off the price of their service

the price of the cleaning is $198

company 1: 25% discount = 75% of the original price $198, which would be $198 * 3/4, or $148.5

company 2: $30 dollars off, which means $198 - $30 or $168

company 3: 1/3rd discount, meaning the product after the discount is only 2/3rd of the original price. 2/3rd of $198 is $132, so the final price after the discount is $132
