Answer:
Rule for stingray tank:
Start at 6 and add 4.
Rule for shark tank:
Start at 0 and add 6.
Table (stingray tank):
Hours: 0, 1, 2, 3, 4, 5, 6
Depth: 6, 10, 14, 18, 22, 26, 30
Graphing:
Coordinates - (0,6) (1,10) (2,14) (3,18) (4,22) (5,26) (6,30)
Table (shark tank):
Hours: 0, 1, 2, 3, 4, 5, 6
Depth: 0, 6, 12, 18, 24, 30, 36
Graphing:
Coordinates - (0,0) (1,6) (2,12) (3,18) (4,24) (5,30) (6,36)
Step-by-step explanation:
The depth of the water in both tanks will be equal in hour 3. The table for the stingray tank shows that at hour 3, the depth of the water will be 18 inches. Correspondingly, the depth of the water will also be 18 inches at hour 3 for the shark tank. My graph further supports my answer because line 1 (stingray tank) intercepts line 2 (shark tank) at (3,18). Therefore, the depth will be equal at hour 3 with 18 inches of water.
