What's the answer to x/9=5/11

1 answer:

3 0

Given : $\dfrac{x}{9}=\dfrac{5}{11}$

Multiply by ( 9 x 11 ) i.e. 99 on both sides,
$= > \dfrac{x}{9} \times 99 = \dfrac{5}{11} \times 99 \\ \\ \\ = > x \times 11 = 5 \times 9 \\ \\ = >x = \frac{5 \times 9}{11} \\ \\ \\ = > x = \frac{45}{11}$

Therefore the numeric value of x is 45 / 11.

Re-write the equation without the h component.

levacccp [35]

Answer:

$f(x) = 2[\frac{3^x}{9}] + 2$

$f(x) = 8(4)^x$

Step-by-step explanation:

Given

$f(x) = 2(3)^{x-2} + 2$

$f(x) = \frac{1}{2}(4)^{x+2}$

Required

Remove the h component

In a function, the h component is highlighted as:

$f(x) = a^{x+h}$

So, we have:

$f(x) = 2(3)^{x-2} + 2$

Split the exponents using the following law of indices:

$a^m/a^n = a^{m-n}$

$f(x) = 2*\frac{3^x}{3^2} + 2$

$f(x) = 2*\frac{3^x}{9} + 2$

$f(x) = 2[\frac{3^x}{9}] + 2$

<em>The h component has been removed</em>

$f(x) = \frac{1}{2}(4)^{x+2}$

Split the exponent using the following law of indices

$a^{m+n} =a^m * a^n$

So, we have:

$f(x) = \frac{1}{2}(4)^x * 4^2$

Express 4^2 as 16

$f(x) = \frac{1}{2}(4)^x * 16$

Divide 16 by 2

$f(x) = 8(4)^x$

Plz help but not if you don't know

I hope this helps you

Euclid

h^2=4.6

h=2 square root of 6

h^2+6^2=base^2

24+36=base^2

base=2square root of 15

h^2+4^2=height^2

24+16=height^2

height=2 square root of 10

Find an ordered pair (x y) that is a solution to the equation calculator

galina1969 [7]

Pick a value for 'x' then solve for the 'y'

Ex: X=6 then 6-2y=2 then 4=2y then y=2y

So your answer will be 6,2.

Another answer to your question would be 4,1.
