F(x) = 4/x-9 g(x)=4/x + 9 find f(g(x))

Alenkinab [10]

Hello,

$f(x)= \dfrac{4}{x-9} \\

g(x)= \dfrac{4}{x+9} \\

f(g(x))=f( \dfrac{4}{x+9} )\\

= \dfrac{4}{ \dfrac{4}{x+9}-9} \\

= \dfrac{4(x+9)}{4-9x-81} \\

=- \dfrac{4x+36}{77x+9x}

How do I solve for x? (the picture has the problem)

max2010maxim [7]

Answer:

x = 21.013155617496

Step-by-step explanation:

we have a right triangle then ,

$\cos \left( 36\right) =\frac{17}{x}$

Then

$x=\frac{17}{\cos \left( 36\right) } = 21.013155617496$

Then

x ≈ 21

If there are 400 ounces in 25 pounds, how many ounces are in 8 pounds

ladessa [460]

The answer is: " 128 oz. " .
_________________________________________________________
There are: " 128 oz. " (in " 8 lbs." ) .
_________________________________________________________
Explanation:
________________________________________________________
Set up a proportion; as a fraction; as follows:
________________________________________________________

400/ 25 = x / 8 ;

in which: "x" = the number of "ounces [oz.] there are in "8 lbs." ;
________________________________________________________
We shall solve for "x" , the answer to the problem:

Cross-factor multiply:

25x = (400) * 8 ;

→ 25x = 3200 ;

Divide each side of the equation by "25" ; to isolate "x" on one side of the equation; & to solve for "x" ;

→ 25x / 25 = 3200 / 25 ;

→ x = 128 .
_________________________________________________________
Answer: " 128 oz. " .
_________________________________________________________
There are: " 128 oz. " (in " 8 lbs." ) .
_________________________________________________________

Note of interest: " 16 oz. = 1 lb. " (exact conversion).

So; "8 lbs. = ? oz. " ;

→ " 8 lbs. * (16 oz/ 1 lb) = ( 8 * 16) oz. = 128 oz. ; → which is our answer!

Consider the accompanying matrix as the augmented matrix of a linear system. State in words the next two elementary row operatio

Lubov Fominskaja [6]

Answer:

The answer is below

Step-by-step explanation:

The next step to solve the system, would be to divide the second row by 3 and we would be left with: 3 * R2

[1 -5 3 0 -2

0 1 -7/3 0 4/3

0 0 1 2 -2]

Then what we will do is multiply row 3 by 7/3 and then subtract it from row 2, that is, R2 - 7/3 * R3, and it would look like this:

[1 -5 3 0 -2

0 1 0 14/3 -10/3

0 0 1 2 -2]

And these would be the next two steps in the process of solving the system.
