1. Take an arbitrary point that lies on the first line y=3x+10. Let x=0, then y=10 and point has coordinates (0,10).
2. Use formula 
to find the distance from point 
to the line Ax+By+C=0.
The second line has equation y=3x-20, that is 3x-y-20=0. By the previous formula the distance from the point (0,10) to the line 3x-y-20=0 is:
.
3. Since lines y=3x+10 and y=3x-20 are parallel, then the distance between these lines are the same as the distance from an arbitrary point from the first line to the second line.
Answer: 
.
Answer:
15 Kg cm²
Step-by-step explanation:
Given that V varies inversely with P then the equation relating them is
V = 
← k is the constant of variation
To find k use the condition
V = 360, P = 20, then
360 = 
( multiply both sides by 20 )
k = 7200
V = 
← equation of variation
When V = 480, then
480 = ( multiply both sides by P )
480P = 7200 ( divide both sides by 480 )
P = 15
