It’s line 4. She subtracted the final from the initial. The distance formula requires you to subtract the initial from the final. That’s the formula for displacement in x and y.
Answer:
<u>42 Hours.</u>
Step-by-step explanation:
As an equation where y is the total pages and x is hours of class:
y=1+1x since she started with 1 page and does 1 page per hour.
Setting the total pages she needs as 43 (y=43) we get:
43=1+1x
Subtract one on both sides
42=1x
The 1 doesn't need to be written so
x=42
Therefore, it'll take her 42 hours to write all those notes.
It is 19 because of the Pythagorean theorem which states a squared plus b squared is c squared.
