If y varies directly as x, and y=24 when x=16,
find y when x=12.​


Sagot :

Answer:

y = 30

Step-by-step explanation:

the initial statement is Y x X

to convert to an equation multiply by k the the constant of variation

y=kx

to find k use the given condition

y = - 24 when x=8

y = kx - k = y = -24 = -3

x 8

equation is y = - 3x

when x = 10 then

y = - 3 x 10 = -30
