Answer:
4 2/3 gallons of gas
Step-by-step explanation:
Step 1
Suppose a car gas tank holds 21 gallons of gas.
On a trip it uses 2/3 of a tank of gas on a trip.
= 2/3 × 21 gallons of gas
= 14 gallons of gas
Step 2
Then it uses 1/3 of what is left in the tank.
The number of gallons of gas left =
21 gallons of gas - 14 gallons of gas
= 7 gallons of gas
Hence, this is calculated as:
1/3 × 7 gallons of gas
= 2 1/3 gallons of gas
Step 3
How many gallons of gas are left in the tank?
This is calculated as:
7 gallons of gas - 2 1/3 gallons of gas
= 7/1 - 7/3
Lowest common denominator =
= 21 - 7/3
= 14/3
= 4 2/3 gallons of gas is left
Therefore, 4 2/3 gallons of gas is left.

Answer:
- y-intercept: y=9
- zeros: x= -3, -1, 1, 3
Step-by-step explanation:
The y-intercept is where the graph crosses the y-axis. On this graph, that is just below y=10. A reasonable estimate* of the y-intercept is y=9.
__
The zeros are those places on the graph where y=0. The line y=0 is the x-axis, so the zeros are the x-values of the places where the graph crosses the x-axis. Those points are clearly labeled: x = -3, -1, 1, 3.
_____
* Knowing the zeros, you can write a factored-form equation for the graph:
y = (x +3)(x +1)(x -1)(x -3)
You can substitute x=0 in this equation to see what the y-intercept would be:
3×1×-1×-3 = 9
That is, with no scale factor applied to the function, its y-intercept would be 9. This is the same value we estimated above, so it is reasonable to assume that value is correct.
