Answer:
(7,-7) that's it according to me
Answer:
If A = {1,20,30..} and B = {4,6} find n(A-B)?
distance = rate * time
rate = distance / time
rate = .75 miles / .666666 hours
rate = 1.125 miles per hours (.125 = (1/8) ) so
rate = 1 plus 1/8 miles per hour. answer is B
1:21 divide both digits by 9
First we need to calculate t(4) because x=4 for 4 shifts.
t(4) = 4*4 +3 = 19
Now because function "c" is declared as c(t(x)) for value x=4 we are searching c(19)! because t(4) = 19
c(19) = 2*19 + 5 = 43.
Answer is 43
