Answer:

1/5

Step-by-step explanation:

i had a similar question

For each roll you start with paying 2 dollars and you only with 10 dollars one out of 6 rolls (on average). 

So the cost for one play is 2 dollars and your win is 10/6. 

Value is -2+10/6=-1/3 dollars

So you lose 1/3 dollars on average with each game

since you have no limited rolls u put 1/5

this from another question but both same just different numbers

Answer:

a) 2

b) -\frac{1}{2}

c) y = 2x + 1

Step-by-step explanation:

a)

First put the equation into slope intersept form (y=mx+b) by...

  • Move the variable to the right-hand side and change its sign : -y = -4 -2x
  • Change the signs on both sides of the equation: y = 4 + 2x
  • Use the commutative property to reorder the terms : y = 2x + 4

Slope intersept form : y = 2x + 4

Parallel lines have the same slope so.... a parallel slope is 2

b)

First put the equation into slope intersept form (y=mx+b) by...

  • Move the variable to the right-hand side and change its sign : -y = -4 -2x
  • Change the signs on both sides of the equation: y = 4 + 2x
  • Use the commutative property to reorder the terms : y = 2x + 4

Slope intersept form : y = 2x + 4

To find a perpendicular slope flip the slope and change the sign : -\frac{1}{2}

c)

First put the equation into slope intersept form (y=mx+b) by...

  • Move the variable to the right-hand side and change its sign : -y = -4 -2x
  • Change the signs on both sides of the equation: y = 4 + 2x
  • Use the commutative property to reorder the terms : y = 2x + 4

Slope intersept form : y = 2x + 4, parellel slope : 2

  • Substitute the x and y values with the given ordered pair: 3 = 2(1) + b
  • Calculate the product: 3 = 2 + b
  • Move the variable to the left-hand side and change its sign: -x = 2 - 3
  • Calculate the difference and change the signs : b = 1

Use the slope and y-intersept (b) to write the new line : y = 2x + 4
