Answer:

9.318 * 10^6.

Step-by-step explanation:

(9.3 * 10^6) + (1.8 * 10^4)

= 9300000 + 18000

= 9318000

= 9.318 * 10^6.

5x3 + 14x2 + 9x <br> help
Cerrena [4.2K]
<h3>Answer:    x(x+1)(5x+9) </h3>

===================================================

Work Shown:

5x^3 + 14x^2 + 9x

x( 5x^2 + 14x + 9 )

To factor 5x^2 + 14x + 9, we could use the AC method and guess and check our way to getting the correct result.

A better way in my opinion is to solve 5x^2 + 14x + 9 = 0 through the quadratic formula

x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(14)\pm\sqrt{(14)^2-4(5)(9)}}{2(5)}\\\\x = \frac{-14\pm\sqrt{16}}{10}\\\\x = \frac{-14\pm4}{10}\\\\x = \frac{-14+4}{10} \ \text{ or } \ x = \frac{-14-4}{10}\\\\x = \frac{-10}{10} \ \text{ or } \ x = \frac{-18}{10}\\\\x = -1 \ \text{ or } \ x = \frac{-9}{5}\\\\

Then use those two solutions to find the factorization

x = -1  or  x = -9/5

x+1 = 0  or  5x = -9

x+1 = 0  or  5x+9 = 0

(x+1)(5x+9) = 0

So we have shown that 5x^2 + 14x + 9 factors to (x+1)(5x+9)

-----------

Overall,

5x^3 + 14x^2 + 9x

factors to

x(x+1)(5x+9)

6x+9/x-5 x is not equal to 5 find inverse
algol [13]
You have f(x)=(<span>6x+9)/(x-5) and want to find the inverse function?  Please note that the parentheses are obligatory here.

1.  Replace "f(x)" with y:   y = </span>(6x+9)/(x-5)
<span>
2.  Interchange the variables x and y:     x</span> = (6y+9)/(y-5)

3.  Solve this result for y:     x(y-5) = (6y+9), or xy-5x = 6y+9.  Then:
                                                             
                                            xy-6y = 9 + 5x, or y(x-6) = 9+5x
                                                             9+5x
                     Then                      y = --------------                       
                                                             x-6

Here x may not = 6, because division by zero would occur otherwise.
