Which of the following ordered pair could NOT be included in this set if it is a function? { (-4, 2), (3, 6), (4, 3), (x, y) } A. (x, y) = (1, 2)
B. (x, y) = (-3, 6)
C. (x, y) = (3, 6)
D. (x, y) = (4, -3)
Answers
Answer: (D) 4, -3
Step-by-step explanation:
In order for the set of coordinates to be a function, there cannot be duplicate x-values. So, there cannot be the following: -4, 3, 4
A) x = 1 this CAN be in the set
B) x = -3 this CAN be in the set
C) x = 3 and y = 6 this is a duplicate of a coordinate already in the set. You can plot this point and still pass the vertical line test
D) x = 4 and y = -3 this cannot be included in the set . It will create two different coordinates passing through x = 4 so will fail the vertical line test.
Answer:
C. (x, y) = (3, 6)
Step-by-step explanation: A function is when x's don't repeat.
The correct answer is C. (x, y) = (3, 6) because it would repeating the x's.
Here's Why:
{ (-4, 2), (3, 6), (4, 3), (x, y) }
If you substitute in (3, 6) for the last ordered pair, it would be repeating the number 3. So, (3, 6) can not be included in the set. But the ordered pairs that would NOT be repeating the x's, are these ordered pairs:
A. (x, y) = (1, 2)
B. (x, y) = (-3, 6)
D. (x, y) = (4, -3)
A, B, & D are ordered pairs that can make this set a function.
Hope this helps you!!! :)

Answer:
Step-by-step explanation:
We are given the following information in the question:
Let x and y be the two addends whose sum is being evaluated.
It is given that the sum is greater than 4 and smaller than 10. This can be written with the help of inequality:
Also, each addend is less than 5. This can the written in the form of inequality:
If we solve these linear inequalities in two variable, we may be able to get the values of x and y.
The common area of the following inequalities gives us the solution to the problem. There could be various values of x and y to give the solution of these inequities.
The addends are less than 5 so it could be 4+4, 4+3, 4+2, 4+1
This shows that Sue might have written 5,6,7, or 8.

Now for the second part. 250 is the total number of pages, so subtract 85 to get the number of pages she hasn't read.
250-85=165
So she has more than 125 pages left.

Prove: A, B and C are collinear.
Answers
Solution:
Given: In the given figure, where there are pair of Quadrilateral, in which AP=A Q, BP=B Q, C P=C Q .
To Prove : A, B and C are collinear.
Construction: Join AC , the point where it intersects P Q is M.
Proof:
AP=A Q, C P=C Q,
So, the quadrilateral A P C Q is a kite.→→If in a quadrilateral One pair of adjacent sides are equal, then the quadrilateral is a kite.
As we know in a kite Diagonals bisect each other at right angles.
∠AMP=∠A M Q=∠CM P=∠C M Q=90°
Also, BP=B Q, C P=C Q.
So, the quadrilateral B P C Q is a kite.
∠B MP=∠B M Q=∠CM P=∠C M Q=90°
As you can see that , 1. ∠AMP +∠CM P=90°+90°=180°→→Shows Point A and C are in line.------------(1)
2. ∠B MP +∠CM P=90°+90°=180°→→→Shows Point B and C are in line.------------------(2)
Combining (1) and (2),
Shows that point A, B,C lie in a line.
It means Points A, B,C are Collinear.
