Answer:
I believe the answer is B.Good luck!
Let n be the number of minimum chimes needed.
$3500=$12n-$125x5
$4125=$12n
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: .
C would be your answer i hope i helped you :) sorry if i’m incorrect. i’m not sure
Answer: -2
Step-by-step explanation:
When x = 1, y = -2.
Hope it helps <3
