Answer:
X = 1 ; x = 7
Step-by-step explanation:
Given the equation:
s=10|x-4|+50
s = sound level in decibels ; x = number of measures of music played
Take away 50 from Both right hand and left hand side of the equation
Recall s = 80
80 - 50 = 10│x - 4│+ 50 - 50
30 = 10│x - 4│
To get rid of the absolute value sign, append ± to left hand side
± 30 = 10x - 40
Minimum value of x : - 30 + 40 = 10x ; 10 = 10x ; x = 1
Maximum value of x : 30 + 40 = 10x ; 70 = 10x ; x = 7

Answer:
i have no idea. But i will answer because i'm still learning.
Step-by-step explanation:
-2 (3a – 2) = 1/3(7 – 3a)
is whats the question
ok its i'm guessing -2 (3a – 2) = 1/3(7 – 3a)
-2.15384615385
Hope this helps ;)
Answer:
3.61
Step-by-step explanation:
We need to use the distance formula for this:
Basically, we find the different between the the x points: -2-(-4)
Thats 2
Next we square 2 to get 4
Now we find the different between the y points: -3-0
Thats -3
Next we square -3 to get 9
Now, we add 9 to 4 to get 13
Finally, we take to square root of 13 to get 3.61
Have a nice day!
