Answer: C
Step-by-step explanation: For a function, each x-coordinate corresponds to exactly one y-coordinate.
To determine whether the graph shown here
is a function, we can use the vertical line test.
The vertical line test tells us that if each x-coordinate on the graph corresponds to exactly one y-coordinate, then any vertical line that we draw on the graph should hit the graph at only one point.
For the graph show here, any vertical line that you draw with hit the graph at only one point which means it does pass the vertical line test.
So this graph is a <em>function</em>.
So you can say that the weight of a koala here can be x.
So x * 1/8 = 2
2 being the chinchilla's weight and the 1/8 coming from the fact that the chinchilla weighs 1/8 of the weight of the koala.
So you can just divide both sides by 1/8 first.
x * 1/8 = 2
/ 1/8 / 1/8
Or,
x *1/8 * 8/1 = 2 * 8/1
x = 16
So the koala weighs 16 pounds.

If you would like to know which unit rate is equivalent to 17 miles per gallon, you can calculate this using the following steps:
17 miles ... x gallon = ?
51 miles ... 3 gallons
x = 17 * 3 / 51 = 1 gallon
17 miles ... x gallon = ?
34 miles ... 4 gallons
<span>x = 17 * 4 / 34 = 2 gallons</span>
The correct result would be: fifty-one miles over three gallons.
