Answer: 14
Step-by-step explanation: (3+8)*(10-8) = 14
Answer:a
Step-by-step explanation:
30t=50(t-1)
30t=50t-50
30t-50t=-50
-20t=-50
t=-50/-20
t=2.5 hours after the freight train leaves the station they will meet
It is an odd-degree polynomial. Therefore...
As the coefficient is negative for x^9.
When x < 0 or x approaches negative infinity, y or f(x) will approach positive infinity.
When x approaches positive infinity, y or f(x) will approach negative infinity.
So it is the second and the third.
