The function r is defined over the set {integers from 40 to 50 inclusive}as r:x-- "the remainder when x is divided by 7" State the value of

1. r(47)

2. x for which r(x)=3

3. x which have zero as their solution

1. r(47)

Remainder of 47 / 7 is 5

2. x for which r(x)=3

Remainder of 45 / 7 is 3

3. x which have zero as their solution

Remainder of 42/7 and 49/7 both are zero - Apr 24th 2005, 11:32 PMdiamondat35Thanks
Thanks for your help. I appreciate it.
