Answer: Cole and his sister Chloe will take 81 minutes to clean the whole house.
Step-by-step explanation:
Total rooms in the house = 9
Total persons to clean the house = 2 (Cole and his sister Chloe)
Time taken by 1 person to clean one=18 minutes
Time taken by 2 persons to clean one room together=18 divided by 2 = 9 minutes
Time taken by 2 persons to clean 9 rooms (which is the total number of rooms in the house)=9 multiply 9 = 81 minutes
therefore, they will take 81 minutes to clean the whole house.

Step-by-step explanation:
y=2x+1
(-0.8; -0.6)
(x, y)
-0.6=2×(-0.8)+1
-0.6=-0.6
it's true
y=-3x-3
-0.6=-3×(-0.8)-3
-0.6=-5.4
it's not true
