Answer:
Step-by-step explanation:
A translation 5 units down, followed by a 180-degree counterclockwise rotation about the origin
A translation 5 units down, followed by a 270-degree counterclockwise rotation about the origin
- Incorrect. It would work with 180-degree rotation.
A 180-degree counterclockwise rotation about the origin, followed by a translation 5 units down
- Incorrect. It would work with the translation 5 units up.
A 270-degree counterclockwise rotation about the origin, followed by a translation 5 units down

Set up two equations:
1st: P (for Price family) + J (for Jenkins family) = 45 hours
2nd: 20P + 35J = 1200 liters
Rewrite the first equation as P = 45 – J
Replace P in the second equation:
20(45-J) + 35J = 1200
Simplify:
900 -20J + 35J = 1200
900 +15J = 1200
Subtract 900 from both sides:
15J = 300
Divide both sides by 15:
J = 300/15
J = 20
Jenkins used theirs for 20 hours
Price used theirs for 45-20 = 25 hours.
