Ed : (0,205)(4,197)
slope(m) = (197 - 205) / (4 - 0) = -8/4 = -2
y = mx + b
slope(m) = -2
(0,205)...x = 0 and y = 205
time to sub
205 = -2(0) + b
205 = b
equation is : y = -2x + 205...so Ed loses 2 lbs per week
Eric :
y = -1.5x + 200...so Eric loses 1.5 lbs per week
when they started, Ed weighed 205 lbs and Eric weighed 200 lbs
* of the two, Eric loses fewer lbs per week. When the two began their respective weight-loss programs, Ed was heavier by 5 lbs.

Answer:
it would be day 4 because if u add all of the tickets up once you get to day 5 it goes over 115
Step-by-step explanation:
Answer:
A) 5 and B) 5
Step-by-step explanation:
A) 5x-12=13
+12 +12 (add 12 to the 13)
5x=25
(then divide 25 by 5 which is 5 so the answer is 5)
B) 8(x+3)=64 (first use distributive property)
8x+24=64
-24 -24 (then subtract 24 to 64 which is 40)
8x=40
(then divide 40 by 8 which is 5 so that is it!)
I believe this is correct, I hope this helps :D
