Answer:
see below (upper left)
Step-by-step explanation:
When the x-values are sequential, a linear function will have y-values that differ by the same amount.
The upper left table has y-values that differ by -2.
The upper right table has y-values that differ by 2, -6, 2. These values are not the same.
The lower left table has y-values that differ by -1, 5, -13. These values are not the same.
The lower right table has y-values that differ by 1, 3, 5. These values are not the same.*
__
The upper left table represents a linear function.
_____
* The <em>2nd</em> differences are a constant 2, so this table represents a <em>2nd</em>-degree polynomial.
-3 (2a-9b+5c)
common factor out the lowest common factor which is -3
2 hr 15 min = 2
![\frac{1}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B4%7D%20)
hours = 2.25 hours
"how far" means distance ... so distance = rate x time
distance = 56 x 2.25 =
126 miles
"how long" means time ... so using the same formula
168 = 56 x time
divide both sides of the equation by 56 to solve
3 hours = time
