It is 3 cause they are all the same leatheth so 3
Answer:
3,14
Step-by-step explanation:
3x+5=6x-4
x=3
y=3x3+5
y=14
x,y=3,14
14=3x3+5
14=6x3-4
14=14
14=14
(x,y)=3,14

Answer:
y = 6
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 3 when x = 9, then
k =
=
=
, thus
y =
x ← equation of variation
When x = 18, then
y =
× 18 =
= 6
