Factorize -6^2+15x+9

Mathematics
2 answers:
just olya [345]3 years ago

Answer:

3 ( x - 3) ( x + 1)

Step-by-step explanation:

I believe the question is

-6x² + 15x + 9

Multiply -6 by 9 = -54

To factorise you find the factor of -54 that will add up to +15.

The factors = 18 & -3.

Rewrite equation by replacing the 15x by the factors.

-6x² + 18x - 3x + 9

Factorise

-6x(x - 3) -3 ( x - 3 )

(x - 3) ( -6x - 3)

(x - 3) -3( x + 1)

-3 ( x - 3) ( x + 1)

I hope this was helpful, Please mark as brainliest

A small company’s net income for the first six months of the year was $76,500 and for the last six months it was $100,000. What
kkurt [141]
Hello

Answer: The ratio of the first 6 months to the last 6 months is 0.765.
First, we need to determine the amount of money they had in each 6 month period.
In the first 6 months they had: 6 x 76500 = 459000
In the second 6 months they had: 6 x 100000 = 600000
Divide the 2 values to find the ratio:  459000 / 600000 = 0.765

Let f(x)=√3x and g(x)=x-6 What's the smallest number that is in the domain of fog?
yaroslaw [1]

9514 1404 393

Answer:

  6

Step-by-step explanation:

Maybe you have ...

  f(x) = √(3x)

  g(x) = x-6

Then ...

  f(g(x)) = √(3(x -6))

The square root function is only defined for non-negative arguments, so we require ...

  3(x -6) ≥ 0

  x -6 ≥ 0 . . . . . divide by 3

  x ≥ 6 . . . . . . . . add 6

The smallest number in the domain of f(g(x)) is x = 6.
