Solve for x 6 (8X minus 1) equals 9 (x + 2)

Mathematics

1 answer:

Oxana [17]3 years ago

8 0

Answer:

x = $\frac{8}{13}$

Step-by-step explanation:

Given

6(8x - 1) = 9(x + 2) ← distribute parenthesis on both sides

48x - 6 = 9x + 18 ( subtract 9x from both sides )

39x - 6 = 18 ( add 6 to both sides )

39x = 24 ( divide both sides by 39 )

x = $\frac{24}{39}$ = $\frac{8}{13}$

Select the correct function. Select the function with an average rate of change of 3 over the interval [1, 3].

Dovator [93]

Answer:

Function g(x)

Step-by-step explanation:

Given

See attachment for functions

Required

Which has an average rate of 3 over [1,3]

The average rate of change (m) is calculated as:

$m = \frac{f(b) - f(a)}{b -a}$

Where:

$[a,b] = [1,3]$

So, we have:

$m = \frac{f(3) - f(1)}{3 -1}$

$m = \frac{f(3) - f(1)}{2}$

From the table f(x), we have:

$f(3) = 6\\ f(1) = -2$

So:

$m = \frac{6 - -2}{2}$

$m = \frac{8}{2}$

$m =4$

From the graph of g(x), we have:

$g(3) = 4\\ g(1) = -2$

So:

$m = \frac{g(3) - g(1)}{2}$

$m = \frac{4 - -2}{2}$

$m = \frac{6}{2}$

$m =3$

Since only one of the function has an average rate of change of 3 over the given interval,

Then g(x) answers the question

Tim has 39 pairs of headphones and 13 music players. Tim wants to sell all the headphones and music players in identical package

dsp73

Answer:

He will have 13 packages containing 3 pairs of headphones and 1 music player each.

Step-by-step explanation:

He has 39 pairs of headphones and 13 music players.

He wants to sell both set of items in identical packages.

To do this he has to divide them in such a way that the same number of both set of objects are in every box.

Let us find the ratio of the pairs of headphones to music players:

39 : 13 = 3 : 1

Therefore, dividing the pairs of headphones into 3 parts and the music players into 1 part, he can have identical packages.

So, he will have 13 packages containing 3 pairs of headphones and 1 music player each.
