3.4    Polynomial Long Division

Dividing :  8x3-6x2-23x+6  

                             ("Dividend")

By         :    x-2    ("Divisor")

dividend     8x3  -  6x2  -  23x  +  6  

- divisor  * 8x2     8x3  -  16x2          

remainder         10x2  -  23x  +  6  

- divisor  * 10x1         10x2  -  20x      

remainder          -  3x  +  6  

- divisor  * -3x0          -  3x  +  6  

remainder                0

Quotient :  8x2+10x-3  Remainder:  0

Graph: y+2= -3/4 (x + 4)<br><br> Click or tap the graph to plot a point.
Anvisha [2.4K]
Answer:

Put the dot on the 5 on the Y-axis


Step-by-step explanation:

Put the initial dot on the 5 on the y-axis (vertical), then it's rise over run if plotting a line. Since it's 3/4 you would go up 3 and over to the right four. You can get the rest of the line by going down 3 from the initial point on five, down left 3.

As part of a board game, players choose 5 unique symbols from 9 different symbols to create their secret password. How many diff
frozen [14]

Answer:

15,120

Step-by-step explanation:

For the first symbol, there are 9 options to choose from. Then 8, then 7, and so on. Since each player chooses 5 symbols, they will have a total of 9\cdot 8 \cdot 7 \cdot 6\cdot 5=\boxed{15,120} permutations possible. Since the order of which they choose them matters (as a different order would be a completely different password), it's unnecessary to divide by the number of ways you can rearrange 5 distinct symbols. Therefore, the desired answer is 15,120.

Answer:

  (x, y) = (10, 4)

Step-by-step explanation:

Opposite sides are the same length, so ...

  ON = LM

  6x -3 = 4x +17

  2x = 20 . . . . . . . . add 3-4x

  x = 10

__

  OL = NM

  x -5 = 3y -7

  10 -5 + 7 = 3y . . . . . substitute x, add 7

  12/3 = y = 4 . . . . . .  simplify, divide by 3

The values of x and y are 10 and 4, respectively.
