Answer:
x = 7
y = 5
Step-by-step explanation:
The applicable rule of exponents is ...
a^-b = 1/a^b
__
For a=-j and b=7,
(-j)^-7 = 1/(-j)^7 ⇒ x = 7
For a=k and b=-5,
k^-5 = 1/k^5 ⇒ y = 5
Answer:
(3, 1/2)
Step-by-step explanation:
The x-coordinate of the midpoint of AB is the arithmetic mean of 2 and 4, which comes out to 3. The y-coordinate of the midpoint of AB is the arithmetic mean of 3 and -2, which comes out to 1/2.
Thus the midpoint of AB is (3, 1/2).
