Answer:
3x - y = 1
Step-by-step explanation:
This will be the same equation written in a different way'
The original equation is:
y = 3x - 1
0 = 3x - y - 1
3x - y = 1.

Answer:
r = 6
Step-by-step explanation:
Given that M is directly proportional to r³ then the equation relating them is
M = kr³ ← k is the constant of proportionality
To find k use the condition r = 4 when M = 160
k =
=
= 2.5, so
M = 2.5r³ ← equation of proportionality
When M = 540, then
540 = 2.5 r³ ( divide both sides by 2.5 )
216 = r³ ( take the cube root of both sides )
r =
= 6
