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:

She only needs 3 sides
take half for the side opposite the river, and divide the remaining part in to two for the other two sides, now we can do the work, but if you have to do more than one of these, a rectangle where one side is free (against a river, a side of a barn, whatever) half is for opposite side, the rest split in two gives other two sides
if we put say y as the side opposite the river, and x as the adjacent sides, then you are told that <span>x+x+y=600</span> i.e. <span>2x+y=600</span>
the area is <span>A=xy</span> and you want it to be as large as possible
solve for y and get <span>y=600−2x</span>
then <span><span>A(x)=x(600−2x)=600x−2<span>x2 and base on that the answer would be 45000</span></span></span>
12% off of 32, because the price is lower than it would be if 17% was taken off of 35
