Answer:
flaimgo/albert
Step-by-step explanation:
The set of ordered pairs below represents a function.
{(–9, 1), (–5, 2), (0, 7), (1, 3), (6, –10)}
Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function.
Select all ordered pairs that could be used to show that this claim is incorrect.
(–9, –6)
(1, 12)
(–10, –10)
(4, 7)
(–5, 1)
Given:
The set of ordered pairs below represents a function.
{(–9, 1), (–5, 2), (0, 7), (1, 3), (6, –10)}
Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function.
To find:
All the ordered pairs that could be used to show that this claim is incorrect.
Solution:
We need to find the ordered pairs that can be replaced with (6,-10) and for which the set is not a function.
A relation is called function if there exist a unique output for each input.
If (-9,-6) is replaces with (6,-10), then the set has two outputs y=1 and y=-6 for x=-9. So, the claim is incorrect.
If (1,12) is replaces with (6,-10), then the set has two outputs y=12 and y=3 for x=1. So, the claim is incorrect.
If (-10,-10) is replaces with (6,-10), then there exist unique output for each input. So, the claim is correct.
If (4,7) is replaces with (6,-10), then there exist unique output for each input. So, the claim is correct.
If (-5,1) is replaces with (6,-10), then the set has two outputs y=1 and y=2 for x=-5. So, the claim is incorrect.
Therefore, the correct options are (a), (b) and (e).

Answer:
x=154/115
Step-by-step explanation:
120x+180-32=2x+6+3x
120x-148=5x+6
115x=154
x=154/115

If BFD and AFC are right angles and
m CFD = 72°, what is the value of x?
18
36
108
72
Answer:
72
Step-by-step explanation:
If BFD is a right angle and it gives you CFD that means that you do 90 - 72 to find CFB cause it 90 all togther
CFB = 18 deg
now it also tells us CFA is a 90 deg angle so we do the same thing
90 - 18 = 72

What angle relationship describes ∠VQR and ∠QRW?
segments UV and WZ are parallel with line ST intersecting both at points Q and R respectively
A) Alternate interior angles
B) Alternate exterior angles
C) Corresponding angles
D) Vertical angles
Answer:
its A on the quiz (alternate interior)
Step-by-step explanation:
The required angle relationship describes ∠VQR and ∠QRW is both angles are alternate interior angles. Option A is correct.
Given that,
Segments UV and WZ are parallel with line ST intersecting both at points Q and R respectively. What angle relationship describes ∠VQR and ∠QRW is to be determined.
Parallel lines are defined as the pair of line that has the distance between the point corresponding to the line are equal and this line met at infinity.
The angle can be defined as the one line inclined over other line.
Since it is to describe that what is the relationship between ∠VQR and ∠QRW.
Here, both angles are interior and alternate in the figure so both angles have a relationship to the alternate interior angle by property of parallel lines.
Thus, the required angle relationship describes ∠VQR and ∠QRW is both angles are alternate interior angles. Option A is correct.

What point is on both lines y=12x+3 and y=x+1
(no graph)
Step-by-step explanation:
by having two equations that have the same point, you can set the two equations equal to each other
y = 12x + 3, y = x + 1
12x + 3 = x + 1
11x = -2
x = -2/11
when you find the the x value, plug it back into either one of the equations
y = x + 1
y = (-2/11) + 1
y = 11/11 - 2/11
y = 9/11
the point (solution):
(-2/11, 9/11)
Answer:
(-2|11, 9|11)
Step-by-step explanation:
