first you need to find the least common denominator which in this case it is 40. since 5 and 8 both go into 40.
5/8 = 25/40
3/5 = 24/40
25/40 - 24/40 =1/40
does this make sense to you?
31.5 divided by 10 is 3.15
A) ((-6-3),(0+4))
(-9,4)
b) ((3-3),(-4+4))
(0,0)
c) yes it is a function since it has an input and an output
