The speed of the puck is thus;
27/1.5 = 18 m/s
3 yards fabric costs $7.47
1 yard fabric costs $7.47 / 3
2 yard fabric costs $7.47 / 3 * 2
= $4.98
so, the extra fabric will cost $4.98
Answer:

Step-by-step explanation:
Simplify your first fraction.

Solve by multiplying your numerators against each other and your denominators against each other.

G( f(-4) )
f(-4) = -16 +7= -9
g(-9) = (3*-9)-5 = -32
Increase = Going up.
Therefore Graph D is increasing. simply logic
