What is the solution to log (9x)-log 3 = 3?
xeze [42]

Answer:

The solution x = \frac{e^{3} }{3}

Step-by-step explanation:

<u>Step 1</u>:-

Given log(9 x) -log 3 =3

we have to use formula  log a-log b=log\frac{a}{b}

log(9 x)- log 3 = log(\frac{9 x}{3} ) =3

Again by using formula log a =b

                                       a = e^{b}

so \frac{9 x}{3} =e^{3}

<u>step 2:</u>-

   3 x = e^{3}

  x = \frac{e^{3} }{3}

The solution of given problem is x=\frac{e^3}{3}

Suppose y varies inversely with x, and y=39 when x=1/3.what is the value of y when x=26
vagabundo [1.1K]

Answer:

y = 1/2

Step-by-step explanation:

Varies inversely

xy = k

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

Find the constant of variation

y = 39 when x = 1/3

k = 1/3 * 39

k = 13

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

what is the value of y when x=26

26y = 13

y = 13/26

y = 1/2
