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

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6

7 is the median   7.875 is the mean
