Answer:

There's only one solution x = 2

Thr solution x = 1 is an extraneous solution.

Step-by-step explanation:

$\frac{1}{x - 1} + \frac{2}{x} = \frac{x}{x - 1} \\ \frac{2}{x} = \frac{x}{x - 1} - \frac{1}{x - 1} \\ \frac{2}{x} = \frac{x - 1}{x - 1} \\ \frac{2}{x} = 1 \\ 2 = x$

Can someone explain? And answer?

Answer:

$25.00

Step-by-step explanation:

You already know that $85 is an additional fee added to the monthly fees.

So, you first have to subtract 85 from $685 to get the total amount of monthly fees paid over 2 years.

685-85= 600

So, you can conclude that $600 is the total amount of monthly fees paid.

Now, you want to divide 600 by (the number of months in 2 years) to get the amount of monthly fees.

Since there is 24 months in 2 years you do:

600/ 24 which equals 25.

In conclusion, you can find that the monthly fee is $25.00.

Simplify, assume the variable represents a positive real number

kotykmax [81]

The simplification of the given expression $\sqrt{18y^{21}$ will be equal to $3\sqrt{2} (y)^{\dfrac{21}{2}}$

<h3>What is simplification?</h3>

The process of reducing the complex mathematical expressions into the simplest form is called as the simplification.

The simplification of the given expression will be:

$=\sqrt{18y^{21}}\\\\\\=(18)^{\frac{1}{2} } \times (y)^{\frac{21}{2}}\\\\\\=3\sqrt{2}\times y^{\frac{21}{2}}$

hence the simplification of the given expression $\sqrt{18y^{21}$ will be equal to $3\sqrt{2} (y)^{\dfrac{21}{2}}$

A small town's population, P, can be modeled by the equation P (t) = 45,000(2.66), where t is the time in years. Is the statemen

ICE Princess25 [194]

A function assigns the values. The statement "The rate of population growth each year is 166%" is true.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

Given the function of the population for the town is $P (t) = 45,000(2.66)^t$ , where t is the time in years. Comparing the given function to the general function of the population,

P(x) = a(1+b)ˣ

Then, the value of b will be 166%.

Hence, the statement "The rate of population growth each year is 166%" is true.

Which equation represents the inverse

STatiana [176]

I'd say A, since there, all the operations are the opposite from the original function.
