<h2>Answer:</h2>

x = {3,4,7,12}

n = {12,7,4,3}

(upside down)

<h2>Step-by-step explanation:</h2>

N = {1,2,3,4,5....}

\:

<h3>if n = 1</h3>

\sf{x = \frac{2n+6}{n-2}}

\sf{x = \frac{2(1) + 6}{1 - 2}}

\sf{x = \frac{2 + 6}{-1}}

\sf{x = \frac{8}{-1}}

\sf{x = - 8}

  • x not N

\:

<h3>if n = 2</h3>

\sf{x = \frac{2n+6}{n-2}}

\sf{x = \frac{2(2) +6}{2-2}}

\sf{x = \frac{4 + 6}{2 - 2}}

\sf{x = \frac{8}{0}}

\sf{x = \infty }

  • x not N

\:

<h3>if n = 3</h3>

\sf{x = \frac{2n+6}{n-2}}

\sf{x = \frac{2(3) +6}{3-2}}

\sf{x = \frac{6 + 6}{1}}

\sf{x = \frac{12}{1}}

\sf{x = 12}

  • x is N

\:

<h3>if n = 4</h3>

\sf{x = \frac{2n+6}{n-2}}

\sf{x = \frac{2(4) +6}{4-2}}

\sf{x = \frac{8 + 6}{2}}

\sf{x = \frac{14}{2}}

\sf{x = 7}

  • x is N

\:

<h3>if n = 5</h3>

\sf{x = \frac{2n+6}{n-2}}

\sf{x = \frac{2(5) +6}{5-2}}

\sf{x = \frac{10 + 6}{3}}

\sf{x = \frac{16}{3}}

  • x not N

\:

<h3>if n = 6</h3>

\sf{x = \frac{2n+6}{n-2}}

\sf{x = \frac{2(6) +6}{6-2}}

\sf{x = \frac{12 + 6}{4}}

\sf{x = \frac{18}{4}}

  • x not N

\:

<h3>if n = 7</h3>

\sf{x = \frac{2n+6}{n-2}}

\sf{x = \frac{2(7) +6}{7-2}}

\sf{x = \frac{14 + 6}{5}}

\sf{x = \frac{20}{5}}

\sf{x = 4}

  • x is N

\:

<h3>if n = 12</h3>

\sf{x = \frac{2n+6}{n-2}}

\sf{x = \frac{2(12) +6}{12-2}}

\sf{x = \frac{24 + 6}{10}}

\sf{x = \frac{30}{10}}

\sf{x = 3}

  • x is N

\:

<h3>conclusion</h3>
  • I found the pattern of numbers that the value of n is 3, 4, 7,12
  • For x, I found the pattern of numbers that the value of x is 12, 7, 4,3

A medical clinic is reducing the number of incoming patients by giving vaccines before flu season. During week 5 of flu season,
8_murik_8 [283]

Answer:

f(x) = -6x +120

Step-by-step explanation:

Let's call y the number of patients treated each week

Let's call x the week number.

If the reduction in the number of patients each week is linear then the equation that models this situation will have the following form:

y = mx + b

Where m is the slope of the equation and b is the intercept with the x-axis.

If we know two points on the line then we can find the values of m and b.

We know that During week 5 of flu season, the clinic saw 90 patients, then we have the point:

(5, 90)

We know that In week 10 of flu season, the clinic saw 60 patients, then we have the point:

(10, 60).

Then we can find m and b using the followings formulas:

m=\frac{y_2-y_1}{x_2-x_1}   and b=y_1-mx_1

In this case: (x_1, y_1) = (5, 90) and (x_2, y_2) = (10, 60)

Then:

m=\frac{60-90}{10-5}

m=-6

And

b=90-(-6)(5)

b=120

Finally the function that shows the number of patients seen each week at the clinic is:

f(x) = -6x +120

Jack can text 180 words in 2 minutes and 45 seconds. What is his unit rate in texts per second?
grigory [225]

Answer: 1.091 which is approximately 1 word per second

Step-by-step explanation:

Jack can text 180 words in 2 minutes and 45 seconds. We would convert 2 minutes to seconds

60 seconds = 1 minute

x seconds = 2 minutes

x = 2×60 = 120 seconds

2 minutes 45seconds = 120+45 = 165 seconds

This means Jack can text 180 words in 165 seconds

Let's find his unit rate in texts per second

if jack texts 180 words in 165 seconds

Then jack texts y words in 1 second

165y = 180

y = 180/165= 1.091 words per second

This is approximately 1 word per second

in a class of 37 students,the number of students who like martial art only is double than the number of students who like athlet
yulyashka [42]

Answer:

number of students who like Athletics only = x = 10 students

number of students who like marshal arts only = 2x = 20 students

Step-by-step explanation:

In a class of 37 students, the number of students who like marshal arts only is

double than the number of students who like athletics only. If 3 students like both

and 4 like none of the games, find out how many students like:

i. Marshal arts

ii. Athletics​

Total students in the class = 37

number of students who like Athletics only = x

number of students who like marshal arts only = 2x

Number of students who like both = 3

Number of students who like none = 4

Total = athletics + marshal art + both + none

37 = x + 2x + 3 + 4

37 = 3x + 7

37 - 7 = 3x

30 = 3x

x = 30/3

x = 10

number of students who like Athletics only = x = 10 students

number of students who like marshal arts only = 2x

= 2(10)

= 20 students

Simplify by dividing negative three over eight divided by five over nine.
goblinko [34]

Answer:

\frac{-27}{40}

Step-by-step explanation:

First we need to write in correct form :

\frac{-3}{8}:\frac{5}{9}

We know how to divide fractions. If we can divide numerator by numerator, denominator by denominator, we just do it. In this example we can not do that.

So, we rewrite first fraction and multiply by reciprocal second ( numerator and denominator change place)

\frac{-3}{8} *\frac{9}{5}

Now, multiply numerator by numerator, denominator by denominator :

\frac{-27}{40}
