Please help this question is difficult

Step-by-step explanation:

Using the following property of logarithms,

[tex]\ln{\left(\dfrac{a}{b}\right)} = \ln{a} - \ln{b}[/tex]

we can write the given equation as

[tex]\ln{(x^2 + 1)} - \ln{(x^2 - 1)} = \ln{\left(\dfrac{x^2 + 1}{x^2 - 1}\right)}[/tex]

[tex]\:\:\:\:\:\:\:\:\:= \ln{\dfrac{x(x + 1)}{x(x - 1)}} = \ln{\left(\dfrac{x + 1}{x - 1}\right)}[/tex]

But recall that [tex]\ln{e} = 1[/tex] so we can write our original equation as

[tex]\ln{\left(\dfrac{x + 1}{x - 1}\right)} = \ln{e}[/tex]

or simply

[tex]\dfrac{x + 1}{x - 1} = e[/tex]

Multiplying both sides by [tex](x - 1),[/tex] we get

[tex]x + 1 = e(x - 1)[/tex]

Solving for x, we get

[tex]x = \dfrac{e + 1}{e - 1}[/tex]

Hello!

Answer:

In order to convert mixed number 8 17/20 to decimal form, you follow these steps:

Convert the proper fraction to a decimal: Divide the numerator by the denominator

17 ÷ 20 = 0.85

Add this decimal number to the whole number of the mixed fraction

8 + 0.85 = 8.85

The mixed number 8 17/20 converted to decimal number is, therefore:

8.85

Hope this helps <3

The mixed number 8 17/20 is equivalent to the decimal number 8.85.

To write the mixed number 8 17/20 as a decimal number, follow these steps:

1. Convert the whole number part (8) to a decimal by simply writing it down: 8.

2. Convert the fraction part (17/20) to a decimal. Divide the numerator (17) by the denominator (20):

  17 ÷ 20 = 0.85

3. Add the decimal obtained in step 2 to the whole number from step 1:

  8 + 0.85 = 8.85

So, the mixed number 8 17/20 is equivalent to the decimal number 8.85.

Answer:

So the first step is asking you to write the explanation on your own paper (Easy! :)

The whole equation is designed for you to get the variable "x" by itself so that you know what number it is equal to. In order to do this you need to follow the steps.

So for the second step you need to add 1 to both sides. This step is so that you can get rid of the 1 on the left side, to do this you need to add 1 because this will cancel out on the left side since you are substracting it. BUT if you add one on the left side, you also need to add it to the right side!!! (Whatever you do on one side of the equal sign you need to do on the other side)! So add one on both sides this will get rid of the 1 on the left and turn the 6 to a 7 on the right side.

NEXT STEP (Multiply both sides by -2) So (-1/2) is the same as saying 1 divided by -2 which is -0.5 as a decimal. If you want to cancel out a fraction you want to multiply it by the denominator (aka bottom number), in this case that number is -2. So if you multiply (-1/2) by -2 this cancels that fraction out on the left side and it disappears, BUT you must do it on the right side too! So you multiply 7 by -2 which is equal to -14.

Now you're left with 5x = -6! Your final step is to get rid on the 5 on the left side. To do this you simply divide it by 5 so that it cancels out on the left side and you're left with x. BUT you still divide on the right side, so x is equal to (-6/5).

I hope this helps!

It is all about getting x by itself.

Answer:

62.5

Step-by-step explanation:

To find average, add up all numbers and divide by how many numbers there are.

34 + 91 = 125

125 / 2 = 62.5

Answer:

62.5

Step-by-step explanation:

Average = (34 + 91)/2 = 125/2 = 62.5

Answer:

The difference is 4 degrees

Step-by-step explanation:

If its difficult for you to subtract negatives just switch them to a positive 1 and 5 now subtract 1 from 5=4  and because the measure being used is degrees the final answer would be 4 degrees.

Answer:

[tex] - 3(x - 1) = - 1(5 - x) \\ \\ 3 - x + 1 = - 5 + x \\ \\ - x - x = - 5 - 3 - 1 \\ \\ - 2x = - 5 - 3 - 1 \\ \\ - 2x = - 9 \\ \\ x = \frac{ - 9}{ - 2} \\ \\ x = 4.5[/tex]

[tex]3 - (x - 1) = - 1 - (5 - x)[/tex]

[tex]3 - x + 1 = - 1 - 5 + x[/tex]

[tex](3 + 1) - x = ( - 1 - 5) + x[/tex]

[tex]4 - x = - 6 + x[/tex]

[tex]4 + 6 = x + x[/tex]

[tex]10 = 2x[/tex]

[tex] \frac{10}{2} = x[/tex]

To convert m/s to mi/min we have to find conversion factor first

1 mile = 1609.344 m

1m = 1/1609.344 miles

1 min = 60 s

1s = 1/60 min

Let’s put mi/min instead of m/s according to equations above

m/s = [1/1609.344 miles] / [1/60 min]

The conversion factor is

f = 60 / 1609.344

Now we can convert m/s to mi/min

V (mi/min) = 2.998 ∙ 108 m/s ∙ f = 2.998 ∙ 108 ∙ (60 / 1609.344) = 1.118 ∙ 107 mi/min

Answer: V = 1.118 ∙ 107 mi/min

Hope u have a good day of learning

1 mile = 1609.344 m

1m = 1/1609.344 miles

1 min = 60 s

1s = 1/60 min

Let's put mi/min instead of m/s according to equations above

m/s = [1/1609.344 miles] / [1/60 min]

The conversion factor is

f = 60 / 1609.344

Now we can convert m/s to mi/min

V (mi/min) = 2.998-108 m/s f= 2.998 108 (60/1609.344) = 1.118-107 mi/min

Answer: V = 1.118 - 107 mi/min

Answer:

Let the required number be x

The quotient of a number and -7, decreased by 2, is 10

According to the above problem, we get

[tex] \frac{x}{( -7)} - 2 = 10 \\ \frac{x}{( - 7)} = 10 + 2 \\ \frac{x}{( - 7)} = 12 \\ x = ( - 7) \times 12 \\ \boxed{x = - 84}[/tex]

Therefore, the required number is -84.

Answer:

$10.17

Step-by-step explanation:

Mean simply is defined as "average", so the average price of a hamburger across five resturaunts is found by adding all of the prices together and then dividing by the number of prices there are.

9.95 + 12.95 + 8.50 + 8.95 + 10.50 = 50.85 dollars, which then you divide by 5, and end up with the solution: $10.17
