Answer:
Hello again the answer is -1/2x
Step-by-step explanation:
Since the Y is multipling the 2 you have to isolate it by dividing it by 2 and move x away from the Y
The answer is D 6^4
6 would be 6^1
6x6 would be 6^2 etc
Isolate the K by subtracting 19 from both sides
(19-19)-k=(4-19)
-k=-15
Get rid of the negative by dividing
-k/-1=-15/-1
k=15
