Answer:
It will take them 3.43 hours.
Step-by-step explanation:
Let T denote the total cookies that need to be cocked. Observe that:
- If Rosanne finishes the cookies in 6 hours, that means that she can make
cookies per hour. - If Dorothy finishes the cookies in 8 hours, that means that she can make
cookies per hour.
Then, by 1) and 2), if they work together would we able to make

cookies per hour.
Therefore, in order to finish the T cookies they will need 
The equation would be: Y= 1/2x-1. Reasoning: Our equation format is Y=mx+b. Consider y to just be there for the mean time, but mx is where we insert our slope. We already know what our slope is in this equation (1/2) so that’s what we’ll insert, changing mx to 1/2x. B is where we put our Y. In this coordinate, our Y is -1 (keep in mind that a coordinate is set up as so: (x,y). Insert all our numbers to replace the variables and you get Y=1/2x-1
