Evaluate g(n-7) if g(x) =x^2-5 / 3x

Answers

Answer:

$g(n-7)=(n^2-14n+44)/(3n-21)$

Step-by-step explanation:

The given function is

$g(x)=(x^2-5)/(3x)$

To find g(n-7), we substitute x=n-7 to obtain;

$g(n-7)=((n-7)^2-5)/(3(n-7))$

Expand the parenthesis to obtain;

$g(n-7)=(n^2-14n+49-5)/(3n-21)$

Simplify:

$g(n-7)=(n^2-14n+44)/(3n-21)$

kalil’s monthly salary is 3,250 plus he earns 1.4% commission on his sales for the month. Kalil’s sales for July were $51000. What was his total earning for July?

Answers

You add the Kalil's monthly salary (3,250) to his sales (51,000), then multiply 1.4% ( as a percent: 0.014)
The equation for this problem is
3,250 + 51,000 (0.014)
54,250 (0.014)
3,964

What is the ratio 10:12 in 1:n

Answers

so 10:12
we want to convert 10 to 1
divide both by 10
10/10=1
12/10=1.2
answer
10:12=1:1.2
n=1.2

$(10)/(12) =(1)/(n)\n\n\sf{Cross~multiply}}\n\n10n = 12\n\n\sf{Divide~both~sides~by~10}\n\n \boxed{\bf{n = 1.2}}$

n = 1.2

What is the number between 3400 and 4400

Answers

first find how many numbers are between the two by subtracting
4400 - 3400 = 1000
now to find half way between the two divide 1000 by 2
1000/2 = 500
so the number between the two is 500 +3400 and 4400-500
which is 3900

To find the midway, we shall first know the difference between the two given.

4400 - 3400 = 1000

1000 is the difference, we shall divide 1000 by 2 to find its half in order to know the midway.

$(1000)/(2)$ = 500

500 is the half of 1000

now either add 500 to 3400 or subtract 500 from 4400, it will give us the same exact answer anyways.

3400 + 500 = 3900
4400 - 500 = 3900

so, 3900 is the number between 3400 and 4400

I an confused need help on number 6

Answers

I think the easiest way to answer all of these is to just go ahead and find the equation of the line first.

I'm pretty sure that by the time you reach this problem, you've learned to find
theequation of a line that passes through two given points. You have twopoints: (2, 100) and (5, 205). The equation of the line through themis [ y = 35x + 30 ].

6). The initial membership fee ... the cost for walking in the door and signing up,
before any months, is $30. (Also the y-intercept.)

7). The cost per month is $35. (The slope of the line.)

8). We already did that, up above. [ y = 35x + 30 ].

9). 'x' in the equation is the number of months.
There are 12 months in one year.

y = 35(12) + 30 = $450

Okay I just do part A as an example.

The number of students who chose the zoo, students who chose the museum, and students who chose the planetarium is 10, 9, and 8 respectively.

10 students /8 students= 1.25.

The number of students who chose the zoo is 1.25 times as many as the students who chose the planetarium.

We do the same thing for B, C, and D.

Hope this helps~
