determine if each function is linear or nonlinear.

drag each function into a box to correctly classify it.

y = x/2 - 19   linear  

3y = x^2   not linear

13y =  1/3 x+5   linear

y = x+25/5   linear

y^3 =x     not linear

Step-by-step explanation:

We know that if the function is of the form y= mx+b it makes a line.

If the y term and the x term are both in the numerator and to the power of 1 and not multiplied by each other, then it is linear.

y = x/2 - 19   linear  ( y = mx+b)

3y = x^2  (x is to the power of 2   )  not linear

13y =  1/3 x+5   linear (y = mx+b)

y = x+25/5   linear (y = mx+b)

y^3 =x   (y is to the third power)  not linear

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
