SOMEONE HELP ASAP PLEASE
Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation.

If y varies directly as x and z, and Y =8/3 when x = 1 and 2 = 4, find y when x = 6 and z = 3.

Step-by-step explanation:

Given y varies directly as x and z then the equation relating them is

y = kxz ← k is the constant of variation

To find k use the condition y = when x = 1 and z = 4 , then

= k × 1 × 4 = 4k ( divide both sides by 4 )

= k

y = xz ← equation of variation

When x = 6 and z = 3 , then

y = × 6 × 3 = × 18 = 2 × 6 = 12

answer: 5100 just subtract
