$8x+5-\sqrt{(x-5)^2}$

The point   -4 -7  is on the line with the k in it

   -7  = k (-4) +7

  14/4 = k =   3 1/2

There are 4^4 = 256 possible ways to distribute the bracelets.

This is much like completing the square for x

x^2 - 6x + 60 =

(x-3)²  - 9 +60 =

(x-3)²  + 51        You can finish, no?

Not sure if Ninchux is correct....or if my answer is correct either...but here it is

10 players must each play 9 others  = 90 games BUT two players are in each game   90 / 2 = 45 games total

5 players L  must each play the other 5 players R =   25 games with   L vs R

5 L must each play the other 4 lefties   = 20  but two players in each game means  10 games with L vs L

Two right handed players would also be 10 games out of total 45        10/45 = 2/9

Anita must play 9 other players in the tournament    9 /45 =   1/5 of the games

Is this incorrect?  The other guy gave the same answer.  Why the negatives?  

It's important to know if letters can be repeated.

Hey, shadow wolf you enrolled in prealgebra to learn algebra not ask others how to do fooking algebra. If you didn't enroll in that, then kindly explain why every single question is completely copied from prealgebra, down to the latex.

EP has already answered this question at https://web2.0calc.com/questions/coordinates_142

Method 1: He can make 1 keychain in 5 minutes so we multiply both sides by 9 and we get 45 minutes.

Method 2: 6*1.5 = 9 so 30*1.5 = 45

Hugo sells handmade key chains online. Yesterday, he made 6 keychains in 30 minutes. Hugo wants to make 9 keychains today. If Hugo works at the same rate today, how long will it take him to make the keychains?  

Hugo averages 30/6 or 5 minutes per keychain.  At this rate, it will take him 45 minutes to make nine.  

Let $A$ be the number of terms in the expansion of $(x+a)^{11}$.  (This $A$ is also the number of terms in the expansion of $(x-a)^{11}$.)  Let $B$ be the number of terms in the expansion of $(x+a)^{11}$ that are the same as the terms in the expansion of $(x-a)^{11}$.  The answer is $A-B$.
 

We know there are 55 total games in the tournament so keep that in mind.

1. There are 5 left-handed players and 5 right-handed players so each left-handed player will play 5 right-handed players so there are 5*5 matches in there so it is 25.

2. Well, that would just be 4+3+2+1 left-hand only matches which will add up to 10 rounds.

3.  It would be the same as the left-handed players which is 10/55 which simplifies to 2/11.

4. Anita will play 9 games so it is 9/55 which cannot be simplified. 

The sum of the first 10 multiples of 5 is 275

The sum of the first 10 positive even integers is 110 

Therefore, the absolute difference is |275-110|=165

Well, that would be 8100*c and c is also 10 so it would be 81000

a/(1-r)

a = 1

r = 1/5^2

Can you take it from here?

Thanks Alan,

Did you work out the answer for this?

My logic, or lack thereof, is that the sides would increase in length by sqrt3

So the are would increase by 3

the original area was 2.5.

That is where I got 7.5 from.  Does that sound right to you?

Another way w/out calculus

Normal force =  9.81 m/s^2 * 35.4 kg

    frictional force = friction coefficient * normal force =   .323 * ( 9.81 * 35.4)

        net force on object = 186.012  -  .323*(9.81*35.4) = 73.84 N

F = ma

73.84  = 35.4 * a       a = 2.086 m/s^2

x = x0 + v0 t + 1/2 a t^2

  = 0   +   0    + 1/2 (2.086)(5.11^2) =  27 .23 meters

Sorry Aj,

Second answerer is rude but also correct.

What have you looked at so far

abcba

any digit can go in the middle,  How many is that?

a can't be 0

So there are 9 choices for a and 10 choices for b.

So how many altogether?

There is a lot of irrelevant info here.

Lets forget the kids.

there are 3 cheesburgers and 3 hamburgers placed in a row.   

there will be  6!/(3!3!) possible orders = 20 altogether.

If the last two are hamburgers then on of the others is also a hamburger, 4 possible places in the line

If the last 2 are cheesburgers then again 4 possible ways.

That is 8 ways that ben and bill can get the same

Prob = 8/20 = 0.4

The posted question is in a dialect of incompetence. There is no solution as presented; there is no known method for separating “eight out of four balls.”   

The presented solution is useless, except as an example of ineptitude. 

This was a little harder than it looked

it is in miles per hour so you must change 5 minutes into hours

You have   45=d/(t+5minutes)      and      63=d/(t-5minutes)

solve simultaneously to get d and t

Then speed = distance/time

then check your answer.

Rectangle

Width = w

Length = w + 5

The area of a rectangle is width*length. 

Trangle

short leg = w

long leg = 2(w+5)

The area of a right triangle is leg*otherLeg/2. 

Can you take it from here?
