Answer:
k=10
Step-by-step explanation:
g(x)=2x^2+ kx+18
when x=-2
g(-2)=2 (-2)^2 -2k +18
Since when x is -2, y =6
6=2 (-2)^2 -2k +18
6=18+8-2k
2k=26-6
2k=20
k=10

Answer:
D
Step-by-step explanation:
If he jogged 
miles every day, and he jogged a total distance of 
miles, then he runs for 
days. This is an extension of the 
or distance equals rate times time.
We plug in for y and x to get that he runs for 
.
So, the answer is 
and we're done!
Answer:
