Answer:
y = 4
Step-by-step explanation:
4*y = 4y
4*4 = 16
4y+16=32
to get 4y alone, we subtract 16 from 32.
32-16 = 16
4y = 16
to get y alone, we divide 4 by 16
16/ 4 = 4
so, y = 4
Your first and second derivatives which are the velocity and the acceleration respectively are correct.
The particle has reverses direction when v(t) ≤ 0 so at interval 2 < t < 5 sec.
You can substitute now t = 2 for s(2) and a(2) for first changing direction. Also t = 5 for s(5) and a(5) for second changing direction.

Step-by-step explanation:
Answer:
(–2.2, –3)
Step-by-step explanation:
y = – 3
y = x – 0.8
Substitute the value of y into the second equation
-3 = x-.8
Add .8 to each side
-3 +.8 = x-.8+.8
-2.2 = x
-3 =y
