Answer: B) Non Linear
In order to find out whether a table is linear or not, the numbers have to have a constant rate of change. in order to see whether they do have a constant rate of change or not, try to count the difference between each number on one side, then the other, and see if the difference is the same.
For instance, the total cost numbers go from $205 to $400, which is a $195 difference. Then it goes from $400 to $595, which is again a $195 difference, but pay attention to how it goes from $595 to $725, which is a $130 difference. That $130 difference automatically makes the graph non linear, since the rate of change for the total cost isn’t a constant $195. Just to be sure, you can check the other side as well.
The Hours go from 2 to 5 (3 hour difference), then 5 to 8 (another 3 hour difference), but then 8 to 10. Since the rate of change isn’t 3 hours through the entire Hour side, the table doesn’t have a constant rate of change, which makes this table a non linear function.
If a table doesn’t have a constant rate of change, it’s non-linear. If a table does have a constant rate of change, it is linear. In this case, since the table doesn’t have a constant rate of change, it’s not linear. This responses is kinda long, but I hope it helped!
Answer:
9.75 hours or
9 hours and 45 minutes
Step-by-step explanation:
Answer:
$0.83 when solved for (when the actual conversion is done it comes out to be $0.82)
Step-by-step explanation:
We are stating that 1 US = 1.21 CAD
Since they are equal we can assume: 
Assume the number we are looking for is x. x US = 1 CAD.
Since they are equal we can assume: 
Both equations are equal to 1, meaning the equations are equal to each other. So, 
⇒⇒⇒⇒ 
Using cross multiplication we get 
We can discard the units (we only needed them to differentiate which currency we were talking about) to get 1 = 1.21x
Solving for x we get x = 1/1.21 = 0.82645
If you wish to round this you would get around 0.83, which is remarkably close to the actual price of 0.82. The reason for difference is in the numbers we use. When we divide 1/1.12131, we get 0.82433, which would round to be 0.82.
Hope this is correct and helps!
