Answer:
For the first table: (0, 10) (1, 15) (2, 20) (3, 25) (4, 30)
For the second table: (-2, 1.04) (-1, 1.2) (0, 2) (1, 6) (2, 26)
For the third table: (-2, 10) (-1, 0) (-1/2, -5/4) (1, 10)

Answer:
181/20
Step-by-step explanation:
9.05=9 5/100 = 9 1/20
9*20+1=180+1=181
181/20
Use the property
(a -b)(a+ b) = a^2 - b^2
49x^2 - 81 = (7x + 9)((7x - 9)
