It is a proper fraction.
An example of an improper fraction is 10/4 because the numerator is bigger than the denominator.
An example of a mixed number is 4 5/7
So 3/7 is proper.

Answer:

Proper

Step-by-step explanation:

An improper fraction has a greater numerator than denominator, a mixed number has a whole number next to it. If the numerator is less than the denominator and there are no whole numbers next to it, the fraction is proper.

What are all values of x for which the series shown converges?

adoni [48]

Answer:

One convergence criteria that is useful here is that, if aₙ is the n-th term of this sequence, then we must have:

Iaₙ₊₁I < IaₙI

This means that the absolute value of the terms must decrease as n increases.

Then we must have:

$\frac{(x -2)^n}{n*3^n} > \frac{(x -2 )^{n+1}}{(n + 1)*3^{n+1}}$

We can write this as:

$\frac{(x -2)^n}{n*3^n} > \frac{(x -2 )^{n+1}}{(n + 1)*3^{n+1}} = \frac{(x -2)^n}{(n + 1)*3^n} * \frac{(x - 2)}{3}$

If we assume that n is a really big number, then:

n + 1 ≈ 1

And we can write:

$\frac{(x -2)^n}{n*3^n} > \frac{(x -2)^n}{(n)*3^n} * \frac{(x - 2)}{3}$

Then we have the inequality

$1 > (x - 2)/3$

And remember that this must be in absolute value, then we will have that:

-1 < (x - 2)/3 < 1

-3 < x - 2 < 3

-3 + 2 < x < 3 + 2

-1 < x < 5

The first option looks like this, but it uses the symbols ≤≥, so it is not the same as this, then the correct option will be the second.

Help mi out plz..... solve using matrix method

HACTEHA [7]

Answer:

x = $\frac{22}{7}$

y = $\frac{3}7}$

Step-by-step explanation:

$2x-3y=5\\5x=4y=14\\\\\left[\begin{array}{cc}2&-3\\5&-4\\\end{array}\right] \left[\begin{array}{c}x\\y\\\end{array}\right] =\left[\begin{array}{c}5\\14\\\end{array}\right]$

Let A = $\\\left[\begin{array}{cc}2&-3\\5&-4\\\end{array}\right]$

The inverse of A multiplied by A = the identity matrix $\left[\begin{array}{cc}1&0\\0&1\\\end{array}\right]$

Inverse of A = $\frac{1}{detA}$ $\left[\begin{array}{ccc}-4&3\\-5&2\\\end{array}\right]$

detA = ad - bc = $-8 - - 15 = 7$

Inverse of A = $\left[\begin{array}{cc}\frac{-4}{7} &\frac{3}{7} \\\frac{-5}{7} &\frac{2}{7}\\\end{array}\right]$

$\left[\begin{array}{ccc}x\\y\\\end{array}\right] = \left[\begin{array}{cc}\frac{-4}{7} &\frac{3}{7} \\\frac{-5}{7} &\frac{2}{7}\\\end{array}\right] \left[\begin{array}{ccc}5\\14\\\end{array}\right] = \left[\begin{array}{ccc}\frac{22}{7} \\\frac{3}{7} \\\end{array}\right]$
