Answer:

1/3

Step-by-step explanation:

Looking at the possibilities ( there are 6)

There are 2 that have the same shirt and shorts of the same color ( white white and blue blue)

That means we have 2 out of 6 that meet the requirements

2/6 = 1/3

If you know that 8x300=2400 how can you find 8x320

34kurt

If you knew that 8*300=2400

Then you could likely figure that 8*20=160

And then just add the two together to get 2560

Find an explicit formula for the geometric sequence -8,-40,-200,-1000

barxatty [35]

<h2>An explicit formula for the given geometric sequence, $a_{n} =\dfrac{-8}{5} (5)^{n}$ </h2>

Step-by-step explanation:

The given geometric sequence:

- 8, - 40, - 200, - 1000

Here, first term(a) = - 8, common ration(r) = $\dfrac{-40}{-8}$ = 5

To find, an explicit formula for the given geometric sequence = ?

We know that,

The explicit formula for the geometric sequence

$a_{n} =ar^{n-1}$

∴ An explicit formula for the given geometric sequence

$a_{n} =(-8)(5)^{n-1}$

$a_{n} =\dfrac{-8}{5} (5)^{n}$

∴ An explicit formula for the given geometric sequence, $a_{n} =\dfrac{-8}{5} (5)^{n}$

Help me with this question

Darya [45]

Answer:

$y = -\frac{5}{4}x -4$

Step-by-step explanation:

Parallel lines have the same slope. The slope of this line is m from y=mx+b. So here the slope is -5/4. Use this slope and a point (-4,1) in the point slope form to write the equation of the line.

$y-y_1 = m(x-x_1)\\y-1 = -\frac{5}{4}(x+4)$

This is the equation of the line. It simplifies to:

$y-1 = -\frac{5}{4}(x+4)\\y - 1 = -\frac{5}{4}x -5\\y = -\frac{5}{4}x -4$
