if y=12 when x=4 , find y when x=12

Sagot :

If this is a direct variation:

y = kx

A.)  12 = k4
       12/4 = k4/4
        k = 3    

B)  y= kx
     y = (3)(12)
     y = 36

(Please indicate next the type of variation, that is, direct, inverse, joint, or combined.  The four have different expressions/equations.  Thanks.)
