What do I do with the minus/negative on number 3?

Treat the absolute value bars like you would parenthesis in the order of operations. Sometimes you see the order of operations called GEMDAS instead of PEMDAS to make that easier. The G is for grouping symbols. You solve the inside, then take the absolute value of that, then make it negative. The answer to the above problem is -2 . Highlight to see the answer

How do I do the bonus?

The bonus is asking for the domain of the part of the graph that is increasing and the domain for the part that is decreasing.

There is a typo on the homework side. Mark out the word "drove" on the second line. If you find any others, let me know!

This is from the side we do in class, not the one that is homework. (The side we do as homework is the one with the signature line.)  Remember to write on the grid if you don't need the space. All Benchmark OR's will have that grid so we need to get used to it. 

1.

Mileage day 1: 50mph(5hours)=250 miles

Mileage day 2: 60mph(5hours)=300 miles

Mileage day 3: 70mph(5hours)=350 miles

Total: 900 miles

2.  

If d=rt  then r=d/t so

900 miles/15 hours= 60 miles per hour

OR

Since he traveled the same hours per day we can add the speeds and divide by 3. 

50+60+70= 180

180/3= 60 mph
