Make a guess and check table to figure out if you do not know it off the top of your head.
The answer is 7 and 7
Answer:
Approximately 50 pounds less carbon (in CO₂) will be produced by the second auto on this trip.
Step-by-step explanation:
We have been given that the combustion of one gallon of automobile fuel produces about 5 pounds of carbon (in CO₂). Two autos are making a trip of 600 miles.
Let us find amount of fuel used by autos by dividing the total distance by their mileage.






Let us find the difference of fuel used by both autos.


Since one gallon of automobile fuel produces about 5 pounds of carbon, so 10 gallons of fuel will produces
pounds of carbon.
Since 2nd auto used 10 gallons less than 1st auto, therefore, 2nd auto will produce 50 pounds less carbon than 1st auto.

= Rounded to 0.44
The correct answer is 0.44
Y = 4+3x
2x+1 = y
Rewrite as two systems of equations.
3x - y = -4
2x - y = -1
Now use the substitution method to find the point of intersection.
You can also graph both equations on the same xy-plane using your graphing calculator to find the desired point.
