Best ResponseYou've already chosen the best response.1solve \(k(9)4=6(9)+k\), then you are forcing the two equations to equal each other when \(x=9\). Since the two functions are each continuous, you will be done.

Best ResponseYou've already chosen the best response.0That's what I did, but the correct answer is 29/4 Here is my solution. 9k4 = 54 + k 9kk=544 8k=50 k=6.25

Best ResponseYou've already chosen the best response.0So I just have to set an equality for the function and solve for the value of unknown variable using the given xvalue. Got it :) Thanks!

Best ResponseYou've already chosen the best response.1yes, you are forcing the two equations to be the same at that point so its like you turn dw:1436317386267:dw

Best ResponseYou've already chosen the best response.0I see... I'll try to do some more. If I got stuck can I ask you again?

Best ResponseYou've already chosen the best response.0For this one, it doesn't give any values for x... so how to solve for k? http://img.ctrlv.in/img/15/07/08/559c77ce4bfca.png
