The 1st set has 5 different values of +y+
for +x+=+1+ and violates definition
--------------
The 2nd set is a function
-----------------------
The 3rd set has
( 1,2 ) & ( 1,1 )
( 2,3 ) & ( 2,2 )
( 3,4 ) & ( 3,3 )
Each of these pairs violates the definition
----------------
The 4th set has ( 2,-7 ) & ( 2,0 ) which
violate definition
Answer:
Step-by-step explanation:
period = 2
/ b where b is 8/5 for this question
period = 2/ 8/5
period = 5*2/8
period = 10/ 8
period = 5/ 4
B that’s the right answer
100 kilometers you solve with a proportion 2/20=10/x
2x=200 so x=100
$1380 is the price of the bike, because $276 multiplied by 5 is $1380
