Answer:
4 = the top row would be 1,2,3,4,5
the bottom row would be 14,28,42,56,70
the equation is y= 14x
5 = yes it is proportional. y=21x
6 =no it is not proportional.
7 = yes it is proportional because y= 7x
Step-by-step explanation:
6
The answer would be x<4
both halves of a diagonal must be equal.
so,
8b - 30 = 6b + 6
2b = 36
b = 18
and
9a - 13 = 5a + 5
4a = 18
a = 18/4 = 4.5
