Question

Can anyone help me with this please?

Answer 1

First you will need to create your own rational expression. This will be your “game piece.” You will also need a coin with two different sides to keep track of “heads” versus “tails.”

game board with starting square. On turn one, if the coin is heads then add x plus 1, over 2 x, if it is tails then add x minus 1, over 3x. On turn two, if the coin is heads then subtract x over x plus 3, if it is tails then subtract x over x minus 4. On turn three, if the coin is heads then multiply x minus 4, over x plus 1, if it is tails then add x minus 1, over 3x. On turn four, if the coin is heads then divide by 6 over x plus 3, if it is tails then divide by 6 over x minus 1. On turn five, divide by the quantity of x over x plus 1, plus x over x minus 1.
Create a rational expression to be your game piece. You may choose from the list of factors below or make your own. There must be a variable term in both the numerator and denominator.
(5x)
(2x)
(x + 4)
(x – 5)
(2x + 1)
(3x + 5)
Turn one. Flip your coin and perform the appropriate operation. Explain to the game master how to add your rational expression to the one on the correct space. Use complete sentences.
Turn two. Flip your coin and perform the appropriate operation. Discuss and identify any possible restrictions that exist with (or in) the resulting rational expression.
Turn three. Flip your coin and perform the appropriate operation. Explain to the game master how to multiply your rational expression to the one on the correct space. Use complete sentences.
Turn four. Flip your coin and perform the appropriate operation. Discuss why the degree of the resulting denominator did not change from your expression’s degree.
Turn five, the final level! Perform the appropriate operation. Using complete sentences, describe the steps you used.

Answer 2

OMG what grade level is this?

Answer 3

Faily simple xD

Answer 4

@mamasherman it's algebra 2 i'm in 11th grade, and @the_fizicx99 Well i'm terrible at math, can you help me?

Answer 5

long assignment, hate those.

Answer 6

@SolomonZelman Same here :/ I wish I understood it. I suck at math.

Answer 7

First step:
Create a rational expression to be your game piece. There must be a variable term in both the numerator and denominator.
(5x)
(2x)
(x + 4)
(x – 5)
(2x + 1)
(3x + 5)

Just pick any two and make them into a fraction...

2x/(x+4) will do

Answer 8

Okay

Answer 9

"On turn one, if the coin is heads then add x plus 1, over 2 x,"
let's just pretend it was heads, so we'll add that ^

2x/(x+4) + (x+1)/2x

Answer 10

Okay so we just add for number 2

Answer 11

"On turn two, if the coin is heads then subtract x over x plus 3"
let's just pretend it was heads again

2x/(x+4) + (x+1)/2x - x/(x+3)

Answer 12

Okay

Answer 13

God this is so long.

I think in turn one we were supposed to combine the fractions... but this is way too difficult with the equation editor not working. so... http://www.wolframalpha.com/input/?i=2x%2F%28x%2B4%29+%2B+%28x%2B1%29%2F%282x%29+%3D+

turn one: Flip your coin and perform the appropriate operation. Explain to the game master how to add your rational expression to the one on the correct space. Use complete sentences.

So: (5x^2 +5x +4)/(2x(x+4))

Answer 14

Yes it is :/ Thanks for helping me though <3

Answer 15

I'll go back to turn 2

Turn two. Flip your coin and perform the appropriate operation. Discuss and identify any possible restrictions that exist with (or in) the resulting rational expression.

(5x^2 +5x +4)/(2x(x+4)) - x/(x+3) =
http://www.wolframalpha.com/input/?i=%285x%5E2+%2B5x+%2B4%29%2F%282x%28x%2B4%29%29+-+x%2F%28x%2B3%29

(3x^3 + 12x^2 + 19x + 12)/(2x(x+3)(x+4))

"Discuss and identify any possible restrictions that exist with (or in) the resulting rational expression."
This will be where the denominator is zero.... so x=0, x=-3, x=-4

Answer 16

"On turn three, if the coin is heads then multiply x minus 4, over x plus 1, if it is tails then add x minus 1, over 3x.

Turn three. Flip your coin and perform the appropriate operation. Explain to the game master how to multiply your rational expression to the one on the correct space. Use complete sentences."

Let's pretend it was tails
(3x^3 + 12x^2 + 19x + 12)/(2x(x+3)(x+4)) + (x-1)/3x

=

(11x^3 + 48x^2 + 67x + 12)/(6x(x+3)(x+4)

Answer 17

"On turn four, if the coin is heads then divide by 6 over x plus 3, if it is tails then divide by 6 over x minus 1.

Turn four. Flip your coin and perform the appropriate operation. Discuss why the degree of the resulting denominator did not change from your expression’s degree."

let's take tails:

Answer 18

wow this is ridiculous how long this expression is getting
(11x^3 + 48x^2 + 67x + 12)/(6x(x+3)(x+4)) divide by 6/(x-1)
http://www.wolframalpha.com/input/?i=%28%2811x%5E3+%2B+48x%5E2+%2B+67x+%2B+12%29%2F%286x%28x%2B3%29%28x%2B4%29%29%29%2F%286%2F%28x-1%29%29

(11x^4 + 37x^3 + 19x^2 - 55x - 12)/(36x(x+3)(x+4))

Answer 19

"On turn five, divide by the quantity of x over x plus 1, plus x over x minus 1.

Turn five, the final level! Perform the appropriate operation. Using complete sentences, describe the steps you used."

(11x^4 + 37x^3 + 19x^2 - 55x - 12)/(36x(x+3)(x+4)) / (x/(x+1) + x/(x-1))

http://www.wolframalpha.com/input/?i=%2811x%5E4+%2B+37x%5E3+%2B+19x%5E2+-+55x+-+12%29%2F%2836x%28x%2B3%29%28x%2B4%29%29+%2F+%28x%2F%28x%2B1%29+%2B+x%2F%28x-1%29%29

so:

(11x^6 + 37x^5 + 8x^4 - 92x^3 - 31x^2 + 55x + 12)
_______________________________________________________
(72x^5 + 504x^4 + 864x^3)

Answer 20

>.< you should check in your lesson, it is ridiculous how long this is. Probably they're asking o follow a specific method. Agent would've figured it out though, hm :l

Answer 21

typo's ;~;
