Derive the equation and equate the derivative to zero.
                              dan/dt = -2n + 6 = 0
The value of n in the equation is 3. We substitute 3 to the original equation,
                                           an = -(3)² + 6(3) - 7 = 2

Answer:

B, C, D, E

Step-by-step explanation:

I just substituted the pairs in so

14 = 6(3) - 4(1)

14 = 18 - 4

14 = 14 yes that works

let's try another pair just so you see

14 = 6x - 4y

14 = 6(-1) - 4(-5)

14 = -6 - (-20)

14 = 14 yes that works

14 = 6(1) - 4(-2)

14 = 6 - (-8)

14 = 14 yes that works

14 = 6(14) - 4(-4)

14 = 84 - (-16)

14 = 100 nope

14 = 6(4) - 4(2.5)

14 = 24 - 10

14 = 14 yes that works
