The cost c, is 55 per ticket t, so the equation is c=55t
Answer:
y = 
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y =
when x =
, thus
=
= 2k ( divide both sides by 2 )
k = 
y =
← equation of variation
When x =
, then
y =
=
= 
Answer:
3
- 4x - 32
Step-by-step explanation:
(3x+8)(x-4)
=3
-12x + 8x -32
=3
- 4x - 32
Width is 70 because 310-30=280
280/4=70
