9.3 Homework booklet questions : 3, 4, 5, 6
3.)
A) Complete the table of values.
T = time, V= volume of water in litres
20t = V
Example:
20t = V
20(3) = V
60 = V
B) Graph the ordered pairs.
C) Is it reasonable to have points between the ones on the graph? Explain.
Yes, because for example, if the hose were on for 2 minutes, 40 L of water would go through.
4)
A) Complete the table of values.
P = number of pages printed, C = cost in cents
15p = C
Examples:
15p = C
15(2) = C
30 = C
B) Graph the ordered pairs.
C) Is it reasonable to have points between the ones on the graph? Explain.
No, because you can't print pages partially.
5)
A) y = 3x - 1 when x = 5
3x - 1 = y
3(5) - 1 = y
15 - 1 = y
14 = y
B) y = 4x + 1 when x = -3
4x + 1 = y
4(-3) + 1 = y
(-12) + 1 = y
(-11) = y
C) y = - x when x = (-4)
0 - x = y
0 - (-4) = y
4 = y
6)
( -2, -1, 0, 1, 2 )
A) y = 4x + 1
B) y = -5x
C) y = 3 - x
Great Job Gabbey!! I like how you made a picture for most answers. Next time you could add a link to a game or video explaining more about this topic.
