Step-by-step explanation:
<span>y" + 9y = 0
m^2 + 9 = 0
m = ± 3i
yH = C1 cos 3t + C2 sin 3t
yP = C3 t sin 3t + C4 t cos 3t

Answer:
-1
Step-by-step explanation:
slope = y2-y1/x2-x1
(5,5) (7,3)
slope = 5-3/5-7 = 2/-2 = -1
Answer: -7=0 --> Impossible
Step-by-step explanation:
2x-7+x-11= 3x-11
2x+x-7-11=3x-11
3x-18=3x-11
3x-18+11=3x
3x-7-3x=0
-7=0
Impossible
