Hello!
Robin can clean 72 rooms in 6 days. How many rooms can Robin clean in 9 days?
We have a proportional magnitude (directly proportional), if we increase the number of days for cleaning, obviously we will have more rooms cleaned, then:
clean rooms __________ days
72 ----------------------------------- 6
y ------------------------------------- 9
multiply the means by the extremes
Answer:
108 clean rooms in 9 days

Answer:
3/32
Step-by-step explanation:
The slope is found by
m = ( y2-y1)/(x2-x1)
= ( 19-22)/(-20-12)
= -3/-32
= 3/32
The four main types of transformations are reflection, rotation, translation, ans dilation. All of these transformation retain their original size except for dilations.
Hope this helps.
Answer:
i did it .but not sure.thanks.
Answer:
Step-by-step explanation:
Check part
Now, replace to the original one.
Done!!
Particular solution
I believe that y'(0) = 4, not y(0) anymore. Since y(0) CANNOT have two different solution.
The last step is to put C1, C2 into your solution. You finish it.
