Answer:

x = 1/2 , x = 1/4 , x = 1/3

Step-by-step explanation:

Factor the following equation --> 24x^3 — 26x^2 + 9x — 1 = 0

You will get ----> (2x - 1) (4x - 1) (3x - 1) = 0

Now make all the above expressions = 0 and solve.

2x - 1 = 0                                4x - 1 = 0                                 3x - 1 = 0

    +1    +1                                    +1    +1                                      +1     +1

------------------                         ------------------                          ------------------

Answer:

x = 10AB = 3BC = 11

Step-by-step explanation:

If B lies between A and C on a line segment, then ...

  AB +BC = AC

  (2x -17) +(x +1) = 14

  3x = 30 . . . . . . . . . . . . . add 16, collect terms

  x = 10 . . . . . . . . . . . divide by 3

  AB = 2(10)-17 = 3

 BC = 10+1 = 11

Answers

Answer:

168000

Step-by-step explanation:

5/14 to the son.

that leaves 9/14 of the total.

these 9/14 we need to split into 1/3rds, as 2/3 of these 9/14 go to the daughter, and then the remaining 1/3 of these 9/14 to the wife.

how do we do that ?

well, here it is simple, as we see right away that the numerator 9 can be easily split into 1/3rds (9/3 = 3).

but in general by multiplying. so 2/3 of 8/14 is

9/14 × 2/3 = 9×2 / 14×3 = 3×2 / 14 = 6/14

and then little surprising 1/3 is

9/14 × 1/3 = 9 / 14×3 = 3/14

now, we know, these 3/14 are 36000.

what we need to know is how much is 14/14 or 1/1 : the whole amount.

well, the easiest way in my opinion is now to bring it to 1/14 (by dividing by the numerator 3) and then multiply it by 14 (the denominator) to bring the sum to the whole (14/14).

it in total, multiply it with the reverse fraction : 14/3

36000 × 14/3 = 12000×14 = 168000

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (1, 1) ← 2 points on the line

m = [tex]\frac{1-(-4)}{1-0}[/tex] = [tex]\frac{1+4}{1}[/tex] = 5
