Pls do 12-17!! im struggling. will give brainliest + 62 points

Answers (all in complete sentence):

12. A linear function because it goes at a constant rate of change.

13. A linear function because it goes at a constant rate of change.

14. A nonlinear function because it doesn’t go at a constant rate of change.

15. a. The missing y-value is 4.20 that makes the table represent a linear function.

     b. y=1.4x is a linear funcation that represents the cost y of x pounds of seeds.

16. The table represents a nonlinear function because the change in the wavelength, x divided by the change in the frequency, y is not constant. Also, when the points from the table are plotted on a graph, they do not form a straight line.

17. The table represents a nonlinear function because the change in the height, x divided by the change in the steps, y is not constant. Also, when the points from the table are plotted on a graph, they do not form a straight line.

Hope this helps and answers your questions :)

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
