6 0

Answer:

Let width of rectangle be x cm.

3x+x+3x+x=39

8x=39

x=39÷8

=39/8

=4/7/8

3x=39/8×3

=117/8

=14/5/8

Hence, length=14/5/8cm while width=4/7/8cm.

Well all you need to do to write the linear equation for this function. I assume you want to know, is that you must obtain 2 points, and calculate the slope, then place the info within the following form.

Y = mx + b
1 of the points has to be the y intercept, which can be obtained from the graph, and the other, any other point, which can also be the X intercept.

So, X intercept - (2,0)
Y intercept - (0,3).

Slope = y/X = 3-0/0-2
Slope = 3/-2 or -3/2.

Now put everything together in form:

Y = mx + b

Y = -3/2x + 3.

I believe this is the solution.

Suppose that z=6^500. Express the following in terms of z.
Studentka2010 [4]

Answer:

1. z^2

2. 14z

Step-by-step explanation:

  • We know that (a^m)^n = a^(mn) = (a^n) ^m

We also know that (a^m)(a^n) = a^(m+n)

  1. 36 can be written as 6^2 and here 36^(500) can be written as (6^2)^500 which also can be written as (6^500)^2 and as already it is mentioned that 6^500 as z we can write the above as <u>z^2</u>

2. 8 x 6^500 = 8z

And we can also write 6^(501) as 6^(500+1) which is equivalent to 6(6^500) which is 6z.

From the above we can make sure that the question is the sum of the above which is 8z + 6z = <u>14z</u><u>.</u>

Rewrite this inequality so y is by itself:<br><br> 3x − 4y ≥ 24.
vazorg [7]

Answer:

y \leq 6 + \frac{3x}{4}

Step-by-step explanation:

3x - 4y \geq 24

-3x                 -3x

(-4y \geq 24 - 3x ) / -4

y \leq 6 + \frac{3x}{4}

professor190 [17]
Well, from 2008 to 2010 is just 2 years, so let's say the initial amount is the 19300 from 2008, how many will it be in 2010?

\bf \qquad \textit{Amount for Exponential Growth}\\\\&#10;A=I(1 + r)^t\qquad &#10;\begin{cases}&#10;A=\textit{accumulated amount}\\&#10;I=\textit{initial amount}\to &19300\\&#10;r=rate\to 20\%\to \frac{20}{100}\to &0.20\\&#10;t=\textit{elapsed time}\to &2\\&#10;\end{cases}&#10;\\\\\\&#10;A=19300(1+0.2)^2
