Answer:

The answer is 12/5 hours

Step-by-step explanation:

As Marcus paints at the same rate so the time to paint the whole bedroom can be estimated dividing the whole bedroom (1) by this rate. The rate of painting can be calculated as:

R= (1/3 bedroom portion) / (4/5 hour) = 5/12 of bedroom per hour

Then the time will be:

T = 1/R = 1/ (12/5) = 12/5 hours

How do you find the minimum? It says the answer but I’m not sure how it is (4,-4)
Brilliant_brown [7]

Answer:

You could use a graphing calculator to see the lowest point in the graph OR you could put that equation into it's completed squared form, which is (x-4)^2 -4. The opposite of -4 in the parentheses is positive 4, and the leftover -4 is the y value. So that also becomes (4,-4)
