Write an equation that describes the following relationship y varies jointly as ac and the square root of z and whenx 3 and z 16 then y 48y class=

Respuesta :

So, y varies jointly as x and the square root of z.

48 = ?3 + ?sqrt16

Using the guessing strategy, we need to find a way to combine 3 and 4 and find 48.

4*3 *4 = 48

12*4 = 48

But 3=x and 4 = sqrt16, z

so, one equation will be:
