The answer to the question is -2
Answer:
(23,-23)
Step-by-step explanation:
If company programmed rozo to walk 3 yards east and 4 yards north each minute, then after 7 minutes rozo walked 3·7=21 yards east and 4·7=28 yards north.
On the coordinate plane north direction is moving down and east direction is moving to the right.
Since rozo walked 21 yards to the right and 28 yards down, then its coordinates became (2+21,5-28)=(23,-23).
Let's do it this way.
80 is equal to 100% and we're trying to figure out what percentage would 40 be.
40 is half of 80. If you add 40 and 40 you'd get 80. So now that we know 40 is half of 80 we just need to figure out what percentage would be half of the whole (the whole is 100%)
So 100 split in half is 50.
So 40 would be 50% of 80.
I hope this helps :)

Since he went 168 miles in 4 hours, then his speed is 42 mph. Then, 504 divided by 42 is 12. It will take 12 hours at a steady pace of 42 mph to reach 504 miles.
In case you're not already aware, the expression is called the "difference quotient" and represents the average rate of change of a function over an interval .
For the function , by substituting we get
Then the difference quotient is
where the last equality holds as long as .
