Hey there!
Linear functions have a continuous change.
Let's check these tables and see if we can tell linear functions from non-linear functions.
The first one is
- we add 1 each time
- we subtract 3 each time

Let's try the next one:
- we add 1 each time
- we add 5 each time

Let's try the third one:
- x values: -1, 0, 1, 2
- - we add 1 each time
- we add 3, then 2, then 1..
So this table doesn't represent a linear function.
Let's check the fourth one:
- we add 1 each time
- we add 1 each time
Thus, Option C is the right option.
Hope everything is clear.
Let me know if you have any questions!

Pythagoras:
sqrt( 9^2+12^2) = sqrt( 81+144) = sqrt(225) = 15! Voila :)

Ten cents= 10,20,30,40 so on.
Question is: is 9 closer to 10 or 0?
9 is 9 numbers away from 0 and only 1 number away from 10. That means 10 is the nearest answer.
Rounded= 10 cents per hour
Mr Sharrone can do 1/3 of the job each hour
<span>the assistant does 1/5 of the job each hour </span>
<span>1(1/3) + H (1/5) = 1 (complete job) </span>
<span>1/3 + 1/5 H = 1 </span>
<span>1/5 H = 1 - 1/3 = 2/3 </span>
<span>H = (2/3) / (1/5) = 10/3 = 3 1/3 hours to complete the job</span>
