Which of the sets of ordered pairs represents a function? (5 points) A = {(1, −5), (8, −5), (8, 7), (2, 9)} B = {(7, −4), (7, −2), (6, −3), (−9, 5)} Only A Only B Both A and B Neither A nor B
Answer:
We conclude that Neither A nor B represents the function.
Hence, the correct option is:
Neither A nor BStep-by-step explanation:
A function relates an input to an output.
For example, a certain animal grows 30 cm each year. Thus, the height of the animal is associated with its age using the function
h (age) = age × 30
Therefore, if the age of the animal is 3 years, the height is:
h(3) = 3 × 10 = 90 cm
Set A
A = {(1, −5), (8, −5), (8, 7), (2, 9)}
Please check that there are duplicated inputs.
i.e. x = 8 is appeared twice.
Thus, set A does not represent the function because the function has repeated inputs or x-values. In other words, each input is not related to exactly one output.
Therefore, the set A of ordered pairs does not represent a function.
Set B
B = {(7, −4), (7, −2), (6, −3), (−9, 5)}
Please check that there are duplicated inputs.
i.e. x = 7 is appeared twice.
Thus, the set B does not represent the function because the function has repeated inputs or x-values. In other words, each input is not related to exactly one output.
Therefore, the set B of ordered pairs also does not represent a function.
Conclusion:
We conclude that Neither A nor B represents the function.
Hence, the correct option is:
Neither A nor BIdentify the description of data that would be best represented by a histogram.

Tammy figured her math exam would be difficult unless she put in at
least 15 hours of study time to prepare. She studied 2½ hours on
Monday, 3 hours on Tuesday, 4¾ hours on Wednesday, and 4 ½
hours on Thursday. Did she study at least 15 hours? Explain.
Answer: She put 14 hours and 45 minutes into studying.
Step-by-step explanation: 2 1/2 hours plus 4 1/2 hours is 7 hours. Plus 3 is 10 hours. Plus 4 3/4 is 14 3/4 hours. 14 3/4 hours is = to 14 hours 45 minutes studying.

Answer:
ASA, SAS, SSS, SAS, ASA
Step-by-step explanation:
In order of attachments, left to right:
1) ASA . . . . the bisected angles are on either end of the common segment. ∆ABC ≅ ∆ADC
__
2) SAS . . . . the vertical angle lies between the sides congruent by virtue of the midpoint being X. ∆RSX ≅ ∆PQX
__
3) SSS . . . . two sides and the shared segment are congruent. ∆KLM ≅ ∆KGM
__
4) SAS . . . . the parts of the bisected angle lie between the congruent sides and the common side. ∆WXZ ≅ ∆YXZ
__
5) ASA . . . . the common segment lies between parts of a bisected angle and ones that are given as congruent. ∆PQR ≅ ∆SQR
Simplify the midpoint of PR.
Q (2b, 2c)
R (2a+2b, 2c)
Pl(0,0)
S (2a, 0)
Answer:
The midpoint of PR is;
(a + b, c)
Step-by-step explanation:
Here, we want to get the coordinates of the midpoint of PR
To get these, we make use of the midpoint formula
Mathematically, that will be;
(x,y) = (x1+y1)/2, (x2+y2)/2
(x1,y1) = (0,0)
(x2,y2) = (2a+2b, 2c)
The midpoint is thus;
(2a+2b)/2 , 2c/2
= (a + b, c )
Answer:
(a+b, c)

An aquarium has a base in the shape of a trapezoid. The base is 80 cm long at the front, 50 cm long at the back, and 30 cm wide (from front to back). The height is 100 cm. What is the volume of the aquarium in litres?
Answer:
The volume of the aquarium is 195 litres.
Step-by-step explanation:
The volume ([tex]V[/tex]), measured in cubic centimetres, of the aquarium is equal to the area of the base multiplied by the height. That is:
[tex]V = \frac{1}{2}\cdot (L+l)\cdot w\cdot h[/tex] (1)
Where:
[tex]L[/tex] - Long leg length of the aquarium, measured in centimetres.
[tex]l[/tex] - Short leg length of the aquarium, measured in centimetres.
[tex]w[/tex] - Width of the aquarium, measured in centimetres.
[tex]h[/tex] - Height of the aquarium, measured in centimetres.
If we know that [tex]L = 80\,cm[/tex], [tex]l = 50\,cm[/tex], [tex]w = 30\,cm[/tex] and [tex]h = 100\,cm[/tex], then the volume of the aquarium is:
[tex]V = \frac{1}{2}\cdot (80\,cm+50\,cm)\cdot (30\,cm)\cdot (100\,cm)[/tex]
[tex]V = 195000\,cm^{3}[/tex]
If we know that a litre equals 195000 cubic centimetres, then the volume of the aquarium is:
[tex]V = 195000\,cm^{3}\times \frac{1\,L}{1000\,cm^{3}}[/tex]
[tex]V = 195\,L[/tex]
The volume of the aquarium is 195 litres.
Can some one help me?
Answer:
W = 10 cm
Step-by-step explanation:
Area of a Triangle and a Rectangle
The area of a triangle of base B and height H is:
[tex]\displaystyle A_t=\frac{BH}{2}[/tex]
The area of a rectangle of width W and length L is:
[tex]A_r=WL[/tex]
We are given the base of the triangle B=6 cm and the height H=8 cm, thus the area is:
[tex]\displaystyle A_t=\frac{6*8}{2}= 24\ cm^2[/tex]
The area of the rectangle is 5 times the area of the triangle, thus:
[tex]A_r=5*24\ cm^2=120\ cm^2[/tex]
If we know the area of the rectangle and its length, we can find the width by solving for W:
[tex]\displaystyle W=\frac{A_r}{L}[/tex]
The rectangle has a length of L=12 cm, thus:
[tex]\displaystyle W=\frac{120}{12}=10\ cm[/tex]
W = 10 cm

How can x + 3 = -2x + 5 be set up as a system of equations? (1 point)
01) y - x + 13
y = -2x + 5
O2) y = x + 3
Y-3x + 11
O3) y = x + 12
y = -2x + 1
O4) y = x + 3
y = -2x + 5
9514 1404 393
Answer:
4) y = x + 3
y = -2x + 5
Step-by-step explanation:
Set each side of the equal sign equal to y.
Left side:
y = x + 3
Right side:
y = -2x +5
If the simple interest on $7,000 for 3 years is $1890, then what is the interest rate?
Answer:
I = Prt
Interest = Principal x rate x time
Step-by-step explanation:
1890 = 7000(3)r
1890 = 21000r
r = 1890/21000
r = .09 or 9%

Salt was mixed with pure water in a 1:3 proportion. What is the percentage of salt in the new solution?
Answer:
25%
Step-by-step explanation:
The proportion of salt in the mixture is 1:3; which means that for every portion of solution, salt makes up 1 part for every 3 parts of pure water.
Thus, salt makes up 1 part of every 1+3=4 portions of solution, or 25% ....................
Answer:
25 percent, because 1/4 is 0.25
fatima donates 20000 rs to a school ,the interest on which is to be used for awarding 5 scholarships of equal value every year. If the donater earns an interest of 10% per annum,find the value of each scholarship
Answer: ₹400
Step-by-step explanation:
The interest is 10% of ₹20,000 which is;
= 10% * 20,000
= ₹2,000
It is to be awarded to 5 scholarships of equal value. Each scholarship is there valued at;
= 2,000/5
= ₹400

Answer: was there a total number of people?
Step-by-step explanation:
Answer:
1720
Step-by-step explanation:
so 45 percent were supporting visiting team
100 is the total
100-45=55
55 percent=people supporting home team
55%=946 people
946/55
17.2=1%
so multiply 17.2 times 45
774 supported visiting team
to find total add 774+946 or multiply 17.2 times 100
1720
