What is the solution to 2logg(x) = logg8+log,(x-2)?<br> x=-4<br> x=-2<br> X=4<br> X= 8

astra-53 [7]

Answer:

x = 4

which agrees with the third listed answer among the given options

Step-by-step explanation:

We can re-write the logarithmic equation using the properties of logarithms:

$2\,log(x)=log(8)+log(x-2)\\log(x^2)=log(8*(x-2))\\log(x^2)=log(8x-16)$

Therefore, the arguments of the log functions must also be equal (and we can solve for "x" by noticing that this expression is the perfect square of a binomial:

$x^2=8x-16\\x^2-8x+16=0\\(x-4)^2=0$

and for this equation to verify, x must be 4

If I have 7 button down shirts, 5 pairs of pants and 3 pairs of shoes that I can wear to work then how many different outfits ca

34kurt

105 different outfits can wear on an individual day

<em><u>Solution:</u></em>

I have 7 button down shirts, 5 pairs of pants and 3 pairs of shoes that I can wear to work

To find: Number of different outfits can I wear on an individual day

First he has to decide on a pair of pants and he has 5 different choices

For each of those choices he has a choice of 7 different button down shirts, so that gives him 5 x 7 = 35 different pant/shirt combinations

For each of those 35 different pant/shirt combinations, he has 3 pairs of shoes he could select, so altogether he has 35 x 3 = 105 different outfits

In short we can say,

different outfits = 7 x 5 x 3 = 105

So there 105 different outfits can wear on an individual day

Answer:

$t=5$ dollars per t-shirt

Step-by-step explanation:

<em>Read the problem and write your equation while following along with it</em>

We have 8 t-shirts

Lets 8 t-shirts be represented by 8t

So for our equation we will place and $8$

<h3>Our equation: $8t$ </h3><h3 />

Now it says we have a coupon that subtracts 4 dollars from our total

<h3>Our equation: $8t-4$ </h3><h3 />

The final part to add to our equation says that our total before tax was 36 dollars

<h3>So here is our equation: $8t-4=36$ </h3><h3 />

<em>add </em> $$$ $4$ <em> to both sides</em>

$8t=40$

<em>Divide both sides by</em> $8$

$t=5$ dollars per t-shirt

-Side note, make sure to spell your question right. It was a tad bit confusing to read at the start.

-Brainliest please :)

Find r<br> 25= r•r•8<br> hurry go fast please

ELEN [110]

Answer:

$r = \frac{5}{2\sqrt{2} } \\r = -\frac{5}{2\sqrt{2}}$

Step-by-step explanation:

25= r•r•8 ⇔ 25/8 = r²

then

$r^{2} =(\frac{5}{2\sqrt{2} } )^{2} \\\\Then\\\\r = \frac{5}{2\sqrt{2} } \\Or\\r = -\frac{5}{2\sqrt{2}}$
