To solve:
T/6-14=-20
+14 +14 ISOLATE T/6: inverse operations on -14. (Add)
-----------------
T/6= 6
*6 *6 ISOLATE T: Inverse operations on 6. (Multiply)
-------------
T=36
Her car had 14.46 gallons of fuel before her trip because 12.86+1.6=14.46
Either way you do it you always get 1500 as your answer.
The answer is sometimes. Hope that helped!
For the first option, since when x is going down (to the left) the function is going up, it's not approaching 0. For the second option, since when x is going up (to the right) it's going up, it's not approaching negative infinity (negative infinity is all the way down). For the third one, since when x is going down the y values are climbing, we can assume that the function's values go to positive infinity. For the last one, since when x=0 y=0, when x=0 the function does not go to infinity
