Answer:
Step-by-step explanation:
balls in yo jaws
-3 is the slope, use y2 - y1 over x2 - x1 equation to solve
2x + 3 = 1 - 4 (calculate)
2x - 3 = -3 (move the constant to the right)
2x = -3 - 3 (calculate)
2x = -6 (divide both sides)
<em>x = -3</em>
Answer:
tanks of gas
Step-by-step explanation:
Let the x be the number of tanks of gas, then
The amount of gas used by first car= 
The amount of gas used by second car= 
The amount of gas used by third car= 
Thus, the total change in the amount of gas for all three cars=

Since, the amount of gas
tanks of gas is used for all three cars.
Therefore, the total amount would be negative .
hence, the answer is
tanks of gas.
