when evaluating a velocity time graph, how can you tell if an object is stopped?
a. when the line of the graph is at 0. b. when the line of the graph is above the x-axis.
c. when the line of the graph is below the x-axis. d. none of the above.

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
