It's not a function because the x value 2 has two y values
Answer:
y = 1/6x + 5
Step-by-step explanation:
-x + 6y = 30
6y = x + 30
y = 1/6x + 5
(b - 3x) + (-5b + 6x - 5)
= b - 3x - 5b + 6x - 5
= b - 5b - 3x + 6x - 5
= -4b + 3x - 5
40*1.2=48
1 represent the entire amount and .2 represents the tax added. When multiplied it would give you 48 as the final price.
