A "derivative" is a rate of change.
The derivative of a plain old number is zero, since numbers never change.
Pi is a number. Its value never changes. Its derivative is zero.
First, subtract 14 from 153.80 to get the ticket prices alone. You would get 139.8
Then, since they’re buying 4 tickets, you divide 139.8 by four to get the individual ticket pricing,
meaning your final answer would be $34.95
153.80=4x+14 ⬅️ y-int form if you need that to solve
3k - (k-2) = (k-2) - (k+7) 3k = (k-2) - (k+7) + (k-2) 3k = 2(k-2) - (k+7) 3k = 2k - 4 - k - 7 3k = k - 11 2k = -11
k = -5.5
Step-by-step explanation:
y = 3x² - 10x - 2
a = 3
b = -10
c = -2
D = b² - 4ac
D = (-10)² - 4.3.(-2)
D = 100 + 24
D = 124
