Answer:
- Rises from left to right
- Vertical Line
- Horizontal Line
- Falls from left to right
Step-by-step explanation:
Keep in mind we read graphs from left to right just like how we read and write.
- A positive slope will be increase from left to right.
- A negative slope with decrease left to right.
- A vertical line will have a undefined slope.
- A horizontal line will have a slope of 0.
We can use those tips to solve the problem.
Option A:
4/5 is a positive slope so it will rise from left to right.
Option B:
No slope automatically means "undefined" so that falls in the definition of a vertical line.
Option C:
A slope of 0 is defined as a horizontal line.
Option D:
-4/5 is a negative slope so it will fall from left to right.
Best of Luck!
Answer:
There will be no pieces of paper left over. Each student will receive 15 pieces of paper.
Step-by-step explanation:
If you divide the 345 pieces of paper between the 23 classmates, you will end up with 15. There is no remainder or decimal, just 15, a whole number. That means that there will be no pieces of paper left over.
The trick is to realize what your choices are.
if m or n or both are divisible by 5, then 2mn will be divisible by 5
I don't know if you know about x mod(5), but in that case there can only be 4 possibilities for m and n
m mod (5) = +/- 2 or m mod(5) = +/- 1
In the first case m^2 = 4 mod(5) and in the second case m^2 = 1 mod(5) N has the same considerations.
If m and n have the same modular results (both are [say] 2 ) then m^2 - n^2 which be 0
If they are different, then (m^2 + n^2) mod 5 = 0
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 3y − 11
