I think it is 50? (Sorry if im wrong tho.)
Answer: oh this is hard
Step-by-step explanation: its b
The range is the difference between the largest and smallest number. So for those numbers the lowest value is 6 and the highest is 16. So 16 - 6 = 10
So the range is 10

LCM = 5 × 3 × 3 × 7 × 2 × 2 × 5
LCM = 6300
<u>Hence, the LCM of 315 , 420 , 525 is 6300</u>
Perpendicular = opposite sign and reciprocal slope
Slope would be 3
Y = 3x + b, plug in point
9 = 3(5) + b, b = -6
Solution: y = 3x - 6
