Answer:
4x +1 is your answer.
Step-by-step explanation:
What you do is you add f(x) and g(x) together.
<em>3x - 1 + (x + 2)</em>
4x +1 is your answer.
Answer:
Infinitely many solutions.
Step-by-step explanation:
Multiply the second equation by -2, then add the equations together
(20x+2y=18)
−2(10x+y=9)
20x+2y=18
−20x−2y=−18
Add these equations to eliminate x
0=0
Infinitely many solutions.
Hello.
The further away from the speakers you are t<span>he less intense the sound will be.
</span>
<span> If sound intensity varies inversely with the square of the distance, you can represent this as: </span>
<span>I = 1/d^2 </span>
<span>If you double the distance: </span>
<span>I = 1/(2d)^2 </span>
<span>I = 1/4d^2 </span>
<span>I = 1/4d^2 </span>
<span>so by doubling the distance, you have 1/4th the intensity.
</span>
Have a nice day
