During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by the equation s = 10│x - 4│+ 50 where s represents the sound level in decibels and x represents the number of measures of music played. Explain in words each step to find the following question:
At what number(s) measures played would the sound level be at 80 decibels?
Answers
Hey Child.
The answer to this is 1 or 7:
To find the range for the number of measures played to satisfy our solution, we must solve for x using s = 80.
Next, we subtract 50 from both sides of the equation.
Next, we divide both sides of the equation by 10
Next, to eliminate the absolute value bars, we will add a ± sign in front of our s value, 3.
Finally, we add 4 to both sides of our equation giving us 4 ± 3 = x
Separating this into two equations, we get 4 - 3 = x and 4 + 3 = x
Therefore, x, the number of measures of music played, must be either 1 or 7.

Answers
put the value of f(x) = 0
f(0) = 7(0)-6
=0-6
= -6
Step-by-step explanation:
f(x)= 7x - 6
f(x) = 0
7x - 6 = 0
7x = 6
x = 6/7 ? (I think you need to solve for x)

Inez and Joel work at a store that sells
cell phones. Inez worked for 7 hours
and 23 minutes. Joel worked for
4 hours and 51 minutes. How much
longer did Inez work than Joel?
2 hours 32 minutes
12 hours 14 minutes
3 hours 28 minutes
3 hours 32 minutes
Answers
Answer:
2 hrs and 32 mins
Step-by-step explanation:
Step 1. Because Inez worked more we are going to start by subtracting the the minutes. 23-51= -28.
Step 2. Now we move on to the hours. 7-4= 3. Know we know that the hour time is going to be three. But wait!
Step 3. Because we can't have negative numbers, we need to subtract some more. 60-28= 32. Now I know that my minutes will be 32.
Step 4. But because we used a negative number we have to subtract another hour from our time.
Answer: 2 hrs and 32 mins

A quadratic function y = f(x) is plotted on a graph and the vertex of the resulting
parabola is (-6, -3). What is the vertex of the function defined as
g(x) = -f(x) + 3?
Answers
Answer:
(6, 6).
Step-by-step explanation:
The negative before f(x) reflects f(x) in the x-axis so this makes the new vertex equal to (-6, 3), then the + 3 translates it up 3 units so the required vertex is
(-6, 6).
