-13x=78
-13x/-13=78/-13
Answers: X=-6
Answer:
B. 1/16
Step-by-step explanation:
f(-4) = 2^(-4) = 1/(2^4) = 1/16
you combine like terms first.
for example: 2x=2+5
add up the two plus 5 so that will give you seven then you're going to divide 2 by 7 so that you isolate the x and you'll get your answer.
Sorry, I didn't quite understand the question here is a clear one, it was made by me personally in the geo-gebra application
