I’m so confused- help please :) (no links)

15

Step-by-step explanation:

Looking at the graph I see from 4-5 its a maximum of 10 students and the 6-7 has half the amount of 4-5 so that would be 15 added together for the amount of students who have more than 3 siblings

Hope this helps!

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

it's 100

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

  n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the  14th  row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)
