Step-by-step explanation:
Your trying to rearrange the equation with v were the r was.
2( v - h ) / k = r
2( v - h ) k / k = rk
2( v - h ) = rk
2( v - h ) / 2 = rk / 2
v - h = rk / 2
v - h + h = rk / 2 + h
v = rk / 2 + h
It would be the last option, (5, -4)
Answer:
y = 2x or x = 1/2y or if you would like numerical values then x = 3, y = 6 and z=4
Step-by-step explanation:
x : y = 1 : 2
y : z = 3 : 2
If x : y = 1 : 2 then we know that 1y = 2x ∴ y = 2x or x = 1/2y
If y : z = 3 : 2 then we know that 3z = 2y ∴ z = 2/3y
