To get the value of DK we use proportionality:
AK/EK=BK/KD
thus plugging the values we get:
14/17=7/KD
getting the reciprocal of getting both sides we have:
17/14=KD/7
thus
KD=17/14×7
KD=8.5
thus
5x-40 if yo are trying to simplify it
Answer:
Divide C values/T values that will tell if it is constant or not and that is the reason.
