Answer:
Step-by-step explanation:
A function satisfying the equation 
is said to be an even function. This denomination comes from the fact that the same relation is satisfied for functions of the form 
with 
even. Observe that if 
is twice differentiable we can derivate using the chaing rule as follows:
implies 
Applying the chain rule again we have:
implies 
So we have that function 
is also an even function.

Answer:
k =3
Step-by-step explanation:
-3k-2k+12 = 2k-9
-5k+12 = 2k -9
Add 5k to each side
-5k+5k+12 = 2k+5k-9
12 = 7k-9
Add 9 to each side
12 +9 = 7k-9+9
21 = 7k
Divide each side by 7
21/7 = 7k/7
3 =k
The answer is B miles per hour
