Is the same as

9x + (-1)(6-x)

9x -6 +x

10x-6

Help on solving, right?

The negative sign changes 6 to -6 and -x to x. Thus, 9x-6+x=10x-6. 

We divide: $\frac{2400}{24}=100.$

0.38 (-3/(1/20)) (-5/8)
0.38(-3 x 20) x (-5/8)
0.38(-60) x -0.625
- 22.8 x - 0.625
= 14.25

$\text{Let }S \text{ be the set of all positive integers invertible mod }4!\\ \text{you can partition }S \text{ into pairs of inverses }(x,~x^{-1})\\ -\\ \text{The product of all the elements mod 4! is equal to the product of the }\\ \text{products of the individual pairs mod 4!}\\ -\\ x \cdot x^{-1} \pmod {4!} = 1 \text{ by definition of multiplicative inverse}\\ \text{The product of all these 1's will be 1, and thus the overall product mod 4!}=1$

Remember that  if we divide by x + a, we are dividing by "-a" in the synthetic division process

So.....  in  x + 3....."a" = 3....so  we are dividing by  " - 3"

So we have

-3   [   7      15       -12

                 -21        18

        ______________

         7      - 6          6

The remainder is 6

the answer is -8 but in mixed fraction is -24/3 am i right

I'll do it

PEMDAS states do the multiplication first, again

2/3 x (-7) = -14/3

2/3 x (-5) = -10/3

Now just add them.

-14/3 + (-10/3) = ?

See if you can get that yourself!

thank you do mind helping me out with this one 2/3 (-7)+ 2/3 (-5)

PEDMAS    says do the mult first 

-1/4 x -8 = 2      then do the add,

-2 +2 = 0

We are testing to see if "5" is a root

We multiply 5 *2 = 10

We add this to the "-1"  and get "9"

Thus....

The answer on the top right is the correct one 

No prob....

Oh! That makes much more sense than my answers! I was confused at first. Thank you!

Remember that  the  "range" refers to the y values covered by the graph

The  range  here is  just   from  - 3 to 6, inclusive

So....every answer is good except for  - 4   and 7

All the others are in the range....

NSS....See if you can do this one based on my answer to your other question

Remember.....we are dealing with the theoretical probability, here....!!!!!

The  experimental probaility of a "1" on the next roll  is

245 / 1230   =

.1992  ⇒ B

Note something, NSS.....this isn't the theoretical probability....past outcomes have no effect on the next roll in the theoretical pobability because these are independent events.....thus the  theoretical probability of rolling a "1" on the next roll is still 1/6  = .1667   !!!!

Last one

The denominator is the only problem

1 / 6   +   1 / [ x + 1 ]    =

[ 1] [x + 1]                       [1] [ 6]

__________  +        __________ =

    6 *[x + 1]                [ x + 1 ] *6

  [ x + 1 ] + 6

 __________   =

   6 [ x + 1]

x + 7

_______

6x + 6

So

[ 5 /1 ]  /   (   [  x + 7]  / [ 6x + 6 ] )  =       { invert the second fraction and multiply }

5         *       [ 6x + 6]                  30x + 30

__              ________   =          ________

1                 [ x + 7]                      x + 7

Second one

x^2 + 3x - 28    factors as    (x + 7) (x - 4)

x^2  -7x + 12  factors as   (x - 3) (x - 4)

So

(x + 7) ( x - 4)               ( x + 7)

_____________  =     _______

(x - 3) ( x - 4)                ( x - 3)

First one

Let x be the number of additional FT's......so we have that

[ 12 + x]

_______  =     .85           multiply both sides by  15 + x

[15 + x ]

12 + x  =  85 [ 15 + x]     simplify

12 + x = 12.75 + .85x        subtract 12, .85x   from both sides

.15x  =  .75     divide both sides by  .15

x =  5

So....she needs 5 more consecutive FT's     [ 12 + 5 =  17   total]

Lee has 5/7 of a gallon of water. He gives 1/2 of a gallon of water to his dog, Gilligan. What fraction of the amount of water that Lee had originally did he give to Gilligan?

Frational amount =

Amt he gave to Gilligan                     (1/2)

_____________________     =       _______   =    (1/2) * (7/5)  =  7 / 10

Amt he started with                           (5/7)

Well done, heureka!!!!

I always learn a lot from your geometric proofs   !!!

Thanks for that reference, PM....I'm not familiar with this......!!!!!
