Answer:
Yes, the relation {(3,2), (4,1), (5,9), (6,12), (7,12)}is a function.
Step-by-step explanation:
The three consecutive numbers are 5, 7, and 9.
Take the number (63) and then divide it with 100, this gives you 1%. Then you want to multiply with with 15 in order to get 15%. The answer becomes:
Convert 2/3 and 4/5 to decimals so
2/3 = .6666666666666...you get it
4/5 = .8
so -0.6, 0.65, 2/3, 4/5
