Answer:
He purchased 125 nails.
Step-by-step explanation:
if each nail cost $0.12 you would take $15 and divide it by $0.12.
Order them in which the number with x are on one side and the rest are on the other side
5x-9x=-8+10-50
-4x=-48
X=-48/-4
X=12
let's recall that i⁴ = 1 so then 
59/125, 472/1000, 236/500
Answer:
1) (6,2) (9,2) (3,8) (3,5)
2) (2,-5) (5,-5) (-1,-11) (-1,-8)
Step-by-step explanation:
For the first question, your reflecting over the x-axis into quadrant I, so you just need to make all the coordinates positive. The numbers stay the same - you just get rid of the negative signs. (6,2) (9,2) (3,8) (3,5)
For the second problem, you subtract 4 from the x-value, and 3 from the y-value.
(6,-2) becomes (2,-5)
(9,-2) becomes (5,-5)
(3,-8) becomes (-1,-11)
(3,-5) becomes (-1,-8)
