Answer:
Step-by-step explanation:
1)a ) Let the constant proportionality =k
Direct proportion.So, y = kx
Plugin y = 6 and x =2 and find k
6 = k*2
6/2 = k
k = 3
Constant proportionality = 3
b) y = 3x
When x = 7 ; y = 3*7 = 21
y = 21
c)When x = 9,
y = 3*9
y = 27
d) When y = 9,
9 = 3*x
9/3 = x
x = 3
e)when y = 30
30 = 3*x
30/3 =x
x = 10
3) y is inversely proportion to x³

b) when x = 4

c) When x = 6

d) When y = 24

Answer:
It has a zero in it so it should be identity property.
Step-by-step explanation: anything with 0 is im pretty sure the Identity problem.

Unit rate = total buttons/ total controllers
Unit rate = 26/2 = 13
Unit rate: 13 buttons per controller
