The behavior of the graph of I and what it means in context can be explained below:
<h3>What is Sound intensity?</h3>
Sound intensity, serves as the power that is been carried by sound waves per unit area and this is usually in the direction perpendicular to that area.
we were given the function 
r represent the Distance from the source of sound
P represent the Power of the sound
when there is increase in the distance from the source the intensity moves to zero.
we can see that there is is an inverse proportion between the Intensity and the distance r which implies that The intensity decreases when the distance increases.

Slope intercept form is y=mx+b
m=slope
b=y intercept
changing 2x+3y=1470 to sloepe intercept form is solving for y
minus 2x both sides and dvide by 3
the slope is -2/3
the y intercept is y=490 or the point (0,490)
to graph it, I would start at the origin and go up 490 units on the y axis and put a point there
then go -2 units up (2 down) and 3 to the right and put a point there
then connect the 2 points with a line
the graph represents the possible x and y values so tha tthe profit is 1470
in function notation, replace y with f(x) to get
graph below
intercepts labeled
2x+3y=1593
they are similar because they have the same slope
the equation is
Answer:yes
Step-by-step explanation: 73x 10 -73 essentially
Answer:350
Step-by-step explanation:
unknown is a
a% of 68=238
a/100 x 68=238
68a/100=238
Cross multiplying we get
68a=100x238
68a=23800
Divide both sides by 68
68a/68=23800/68
a=350
Answer: x= -7
Explanation: These equations together should equal 180 because it is a line. Therefore
x + 67 + x + 127 = 180
Combine like terms
2x + 194 = 180
Then
2x = -14
x= -7
