Answer: I think distributive
Step-by-step explanation:
Answer:
First differences means take the ordered pairs in increasing order for their x coordinates (assuming the x's go by ones), then subtract each y (except the last) from the y that comes after it. Keep doing that and you get the first differences. (The second differences would be what you get if you then subtract each of the first differences from the one that came after it (TMI probably but ...)
Say the points were (1,3), (2,7), (3,11) and (4,15). The first differences are
7-3 = 4
11-7 = 4
15 - 11 = 4 all 4. This would also be the slope. So that is the relationship - they are the same.
$0.30x=y should be the answer because there is a 30cent fee for every day and x represents how many days it's kept therefore you would add 30 cents for every day it's kept so it's valid to say $0.30x=y becaue the 30 cents times the total of days it's kept = y (the toatl)
Answer:
just do 20 percent of 1200 then add it to 1200
Answer:
6.70m/s
Step-by-step explanation:
Speed = distance/time
Given the winner covered a distance of 26m in time of 3.88 seconds
Therefore
Speed = 26/3.88
= 6.70m/s
