Answer:
x= .5 (not 100% sure but I think that's right)
Step-by-step explanation:
2x = 1
x= .5
Answer:
x=1.5
Step-by-step explanation:
5x + 2 = 3x + 3
subtract 2 from both sides
5x + 2 - 2 = 3x + 3 - 2
simplify
5x = 3x + 1
subtract 3x from both sides
5x - 3x = 3x + 1 - 3x
2x = 1
divide both sides by 2

An online shopping club has 13000 members when it charges $7 per month for membership. For each $ monthly increase in membership fee, the club loses approximately 500 of its existing members. Write and simplify a function R to represent the monthly revenue received by the club when x represents the price increase.
Hint: Monthly revenue = # members•monthly fee
Just a answer with work will do, ill brainliest the best one.
Answers
Answer:
The function is: [tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]
Step-by-step explanation:
Total members=13000
Membership charge per month=$7
Increase in Membership charge per month=$1
For each $1 monthly increase in membership fee, the club loses approximately=500 members
For 1 month, 1 dollar decrease is 500 × 1
For x months, the decrease in the members is 500 × [tex]x[/tex] =[tex]500x[/tex]
The increase in membership fee is 7 + [tex]x[/tex]
After that,
Monthly revenue = Number of members × Monthly fee
Monthly revenue = [tex](13000-500x)[/tex] × [tex](7 + x)[/tex]
[tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]
Hope this helps and have a nice day!
Still waiting for the server? How does your web browser get a file from the
Internet? Your computer sends a request for the file to a web server, and the web
400 server sends back a response. Let Y = the amount of time (in seconds) after the
start of an hour at which a randomly selected request is received by a particular
web server. The probability distribution of Y can be modeled by a uniform density
curve on the interval from 0 to 3600 seconds. Find the probability that the request
is received by this server within the first 5 minutes (300 seconds) after the hour.
Answers
Answer:
Your computer sends a request for the file to a Web server, and the Web server sends back a response.
Step-by-step explanation:
Using the uniform distribution, it is found that there is a 0.0833 = 8.33% probability that the request is received by this server within the first 5 minutes (300 seconds) after the hour.
----------------------------------
An uniform distribution has two bounds, a and b.
The probability of finding a value of at lower than x is:
[tex]P(X < x) = \frac{x - a}{b - a}[/tex]
The probability distribution of Y can be modeled by a uniform density curve on the interval from 0 to 3600 seconds, thus [tex]a = 0, b = 3600[/tex].
Probability in the first 5 minutes(300 seconds) is:
[tex]P(X < 300) = \frac{300 - 0}{3600 - 0} = 0.0833[/tex]
0.0833 = 8.33% probability that the request is received by this server within the first 5 minutes (300 seconds) after the hour.

Problem 11
Answer: h = 2A/b------------------
Explanation:
We need to get h by itself. To do so, we first multiply both sides by 2. Then we divide both sides by b
A = (1/2)*b*h
2A = b*h
b*h = 2A
h = 2A/b

Problem 12
Answers:Equation: (n+2)/5 = 14Solution to that equation: n = 68------------------
Explanation:
The number n is increased by 2 to get n+2
Then we divide by 5 to get (n+2)/5
This is set equal to 14 to get the equation (n+2)/5 = 14
Solving the equation would look like this
(n+2)/5 = 14
n+2 = 5*14 .... multiply both sides by 5
n+2 = 70
n = 70-2 .... subtract 2 from both sides
n = 68

Problem 13
Answer: Not a solution------------------
Explanation:
We'll replace every copy of x with -3 and simplify
-2x + 5 > 13
-2*(-3) + 5 > 13
6 + 5 > 13
11 > 13
The last inequality is false because 11 is not greater than 13. Since the last inequality is false, this makes the first inequality false when x = -3.
Therefore, x = -3 is not a solution.

Answers
Answer: (x,y) -> (x,-y)
Step-by-step explanation:
If you take any point, for example (-1,1) from the blue shape, you have to multiply the y value by -1 to get to (-1,-1) for the red shape. You can test it out with any point on the two figures.
Also, by looking at it, you can see that it is a reflection over the x axis and a reflection over the x axis always just multiplies the y value by -1.

4. Which of the following values of x is not in the domain of f (x) = log; (10-2x)?
Answers
Answer:
its choice 3) 5
Step-by-step explanation:
We want to see which of the given values of x is not in the domain of f(x) = log(10 - 2x).
The correct option is (3); x = 5.
The domain is defined as the possible inputs of a given function f(x), in this particular case, we have:
f(x) = log(10 - 2x).
Remember that the logarithmic function is only defined for positive arguments, so the values of x that are NOT in the domain of f(x), are these x values such that:
10 - 2x ≤ 0
Solving it for x we have:
10 ≤ 2x
10/2 ≤ x
5 ≤ x
So any value of x equal to or larger than 5 is not in the domain of the given functions, and of the shown options, the only one that is equal or larger than 5 is x = 5, the third option.
So the correct option is the option (3).
