Answer:
The sound level would be at 80 decibels at 1 or 7 number of measures played
Step-by-step explanation:
Equations with Absolute Values
We have the function s to represent the sound level in decibels:
[tex]s = 10|x - 4|+ 50[/tex]
Where x is the number of measures of the music played.
We are required to find the value of x that makes s=80 decibels. We have to find the equation:
[tex]10|x - 4|+ 50 =80[/tex]
Subtracting 50:
[tex]10|x - 4| =80-50[/tex]
[tex]10|x - 4| =30[/tex]
Dividing by 10:
[tex]|x - 4| =30/10=3[/tex]
[tex]|x - 4| =3[/tex]
For the absolute value be equal to 3, its argument could be positive or negative:
[tex]x-4=3[/tex]
Or
[tex]x-4=-3[/tex]
This leads us to two solutions:
[tex]x=3+4=7[/tex]
x=7
Or
[tex]x-4=-3[/tex]
[tex]x=4-3=1[/tex]
x=1
The sound level would be at 80 decibels at 1 or 7 number of measures played

the answer to you question is x=2
Your soccer team isnt holding a silent auction dinner as a fundraiser to pay for school uniforms. The list shows all the expenses for the silent auction, 1) a tablet costs $280 2) football tickets that cost $100 3) a gift card that cost $20 4) the cost of the food is $400. The members of the soccer team will be selling tickets to the silent auction. A ticket to the silent auction includes chances to win prizes and dinner. The ticket cost is set so that 50 tickets will pay for the cost of food and prizes and food. Part a determine the cost per ticket. Part B build a function that can be used to find the total profit, f(x), the soccer team earns by selling x tickets. Show your work to build a function. Part C your soccer team needs to raise at least $300 more than the total cost of the expenses. What is the minimum number of tickets that must to be sold in order for your team to reach their goal? Use the mathematics to justify your response.
Answer:
A) $16
B) p(x) = 16x -800
C) 69 tickets
Step-by-step explanation:
A) The total of expenses is ...
$280 +100 +20 +400 = $800
If this is covered by 50 tickets, then a ticket must provide revenue of ...
$800/50 = $16
The cost per ticket is $16.
__
B) The profit is the difference between revenue and expenses. The revenue from sale of x tickets will be 16x. The expenses are fixed at 800, so the profit is ...
p(x) = 16x -800
__
C) We can find the number of tickets to sell (x) in order for profit to be at least $300 by solving the inequality ...
p(x) ≥ 300
16x -800 ≥ 300 . . . . . use the expression for p(x)
16x ≥ 1100 . . . . . . . . . add 800
x ≥ 68.75 . . . . . . . . . . divide by 16 . . . (the least satisfactory integer is 69)
In order to raise at least $300, the number of tickets sold must be at least 69.

Solve x-7y=16 for y
Answer:
y = (x-16)/7
Step-by-step explanation:
x - 7y = 16
~Subtract x to both sides
-7y = 16 - x
~Divide -7 to everything
y = (16-x)/7
Best of Luck!
Answer:
y = 1/7 x -16/7
Step-by-step explanation:
x-7y=16
Subtract x from each side
x-x-7y=16-x
-7y = -x+16
Divide each side by -7
-7y/-7 = -x/-7 +16/-7
y = 1/7 x -16/7

confused.
Answer:
x=3
Step-by-step explanation:
To solve for x in the given equation,follow the steps below.
2-(3x-4)=2x-9
clear bracket
2-3x+4=2x-9
6-3x=2x-9
collect like-terms
2x+3x=6+9
5x=15
divide bothsides by 5
The solution to given equation is 3.
The given equation is 2-(3x-4)=2x-9.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, 2-(3x-4)=2x-9
2-3x+4=2x-9
6-3x=2x-9
6+9=2x+3x
15=5x
x=15/5
x=3
Therefore, the solution to given equation is 3.

d) milimeters
Answer:
meters squared
Step-by-step explanation:
kelvin is used to measure temperature. so that isn't it. centimeters cubed is a small measurement and isn't used for a 2d surface like the rug that covers the floor. and millimeters is too small to measure for a rug. the answer is meters squared.

7y – 4 = 9y + 13 – 4y
A. y = 17/2
B. y =9/2
C. y=17/12
D. y= 3/4
Answer:
A
Step-by-step explanation:
Given
7y - 4 = 9y + 13 - 4y ( simplify right side )
7y - 4 = 5y + 13 ( subtract 5y from both sides )
2y - 4 = 13 ( add 4 to both sides )
2y = 17 ( divide both sides by 2 )
y = [tex]\frac{17}{2}[/tex]

C=85x+60
Solve the equation for x
Answer:
( C - 60)/ 85 = x
Step-by-step explanation:
C=85x+60
subtract 60 from each side
C-60=85x+60-60
C - 60 = 85x
Divide each side by 85
( C - 60)/ 85 = 85x/85
( C - 60)/ 85 = x

What does the function f (14) = 11 mean
Answer:
In general, when y = f(x), you are substituting a permissible x value into function f & its calculated 'output' is the value for y. Then (x,y) is an ordered pair, i.e. coordinates of a point on the graph. ... So our ordered pair is (-14,11).
Answer: 11= y and 14=x
Step-by-step explanation: The x coordinate is 14 and the y coordinate is 11.

Solve the equation y = ax − b for the variable x.
A. x = ya + b
B. x = a+by
C. x = y + ba
D. x = y+ba
Answer:
(y+b)/a = x
Step-by-step explanation:
y = ax − b
Add b to each side
y+b = ax − b+b
y+b =ax
Divide each side by a
(y+b)/a = ax/a
(y+b)/a = x
Answer:
