Answer:
sum=2a
diff.=-2b
Step-by-step explanation:
a-b+a+b=
2a
a-b-a-b=-2b
You need to find the slope first. (-9,-4). (3,4)
-4-4= -8
-9-3 =-12. Slope is -8/-12 or 8/12 or 2/3
Perpendicular is the negative reciprocal. Or flip over the 2/3 and make it negative.
The answer is - 3/2
Answer:
B
Step-by-step explanation:
Hello there! I am EnjoyingLife, and I hope you find my answer helpful.
First of all, since all books cost less than $5, the most expensive a book could be is $4.99 (remember, less than, not less than or equal to)
Now, let's write an inequality to represent the cost of books.
We know that all books cost less than $5.
We have a sign for "less than". It's "<"
Thus,
p<5
Hope it helps!
Have an awesome day!
Good luck!
