Answer:
Alison wins against Kevin by 0.93 s
Step-by-step explanation:
Alison covers the last 1/4 of the distance in 3 seconds, at a constant acceleration
, we have the following equation of motion

where s (m) is the total distance, ta = 3 s is the time


Similarly, Kevin overs the last 1/3 of the distance in 4 seconds, at a constant acceleration
, we have the following equation of motion:

tk = 4 s is the time


Since
we can conclude that
, so Alison would win.
The time it takes for Alison to cover the entire track



The time it takes for Kevin to cover the entire track



So Alison wins against Kevin by 6.93 - 6 = 0.93 s
-6×-6=36
f-34=36
34+36=70
f=70
Answer:
He failed to flip the inequality
y ≤-1/2x-4
Step-by-step explanation:
-x-2y ≥8
Add x to each side
-x+x-2y ≥x+8
-2y ≥x+8
Divide by -2. Remember to flip the inequality
-2y/-2 ≤-1/2 x +8/-2
y ≤-1/2x-4
Shawn shaded the wrong side of the line.
Y is less than or equal to . He failed to flip the inequality
