How to Calculate Midpoint?
The x-coordinate of the midpoint M of the segment
is the arithmetic mean of the x-coordinates of the endpoints of the segment
. Similarly, the y-coordinate of the midpoint M of the segment
is the arithmetic mean of the y-coordinates of the endpoints of the segment
.
Answer:
The slope of (-4,3) (-8,5) is perpendicular to this line.
Answer: The new solution set is 
Step-by-step explanation: Given that the solution set of a polynomial inequality is (-3, 3).
We are to find the solution set if the inequality symbol is reversed.
Let x denotes the unknown variable in the original inequality.
Then, according to the given information, we can write

Now, if we reverse the sign of the inequality, then the value of x will be

This new solution set can be written as

Thus, the new solution set is 
The answer is 12,662 books in the math section.
Since the science section represents 1/3 of the total books, divide 75,972 by 3.
75,972 ÷ 3 = 25,324 books in the science section.
Now, subtract 25,324 science books from the total number of books.
75,972 - 25,324 = 50,648 remaining books.
Divide the remaining books by 4 and then multiply by 3.
50,648 ÷ 4 = 12,662 • 3 = 37,986 business books.
Add the science books and business books together.
25,324 + 37,986 = 63,310 science and business books.
Subtract 63,310 from 75,972.
75,972 - 63,310 = 12,662 books in the math section.
