Answer:
Midpoint Formula= (x1+x2)/2, (y1+y2)/2
Plug in the numbers
Answer= (0, 0)
I hope this helps you!!
14^(7x) = 17^(-8-x)
Take the log of both sides:
7x*log 14 = -(8+x)*log 17, or 7x^log 14 = -8*log 17 - x*log 17.
Grouping the x terms, we get x(7*log 14 + log 17)= -8*log 17
Then:
-8*log 17
x= -------------------------- (answer)
7*log 14 + log 17
Well first, you have to know the distance formula. You plug the coordinates into it and you get the answer.

√1² + -7² = d
d = 7.1
