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:
<h2>Supplementary angles</h2>
Step-by-step explanation:
Supplementary angles add up to 180°.
m∠VST = m∠VSW + m∠TSW
m∠VST = 180° → m∠VSW + m∠TSW = 180°
Answer:
g(x) approaches negative infinity
Step-by-step explanation:
g(x) = -x² + 2x + 4
limit at g(x) approaches infinity = -(∞)² + 2(∞) + 4 = -∞
I can't solve for f(x) because you didnt give me f(x)
It's B because u have to divide them
Answer:
Mistake -2(x+5)=-2x+10, -2(x+5)=-2x-10
Step-by-step explanation:
7(x-10)-2(x+5)=4x-7+6x-3
7x-70-2x-10=10x-10
5x-80=10x-10
-80+10=10x-5x
-70=5x
-70/5=x
-14=x
