Set A and Set B
Please select the best answer from the choices provided
A
B
C
D
Answer:
d. Set A and Set B
Step-by-step explanation:
We have been given three sets:
Set A: (5, 2), (4, 3), (3, 4), (2, 5)
Set B: (-1, -6), (0, 2), (1, 2), (3, 6)
Set C: (2, 1), (4, 2), (2, 3), (8, 4)
Now we need to state about which of the following sets of ordered pairs represent a function.
We know that a function can't have repeated values in domain that is x-value can't repeat.
we see that set C has repeated x-value "2".
Then set C is not a function.
Hence correct choice is:
d. Set A and Set B
Answer:
A and B represent functions.
Step-by-step explanation:
In a function, any input (x-) value may have only one associated y value. If the same input appears more than once, we know immediately that the data do not represent a function.
A: The inputs are unique: {5, 4, 3, 2} so this is a function.
B: The inputs are unique: {-1, 0, 1, 3}, so this is a function.
C: 2 is used twice as input, so this is not a function.
x = 1
x = 2
x = 5
x = 6
Answer: x = 6
Step-by-step explanation:
Let's solve your equation step-by-step.
81x=27x+2
Solve Exponent.
81x=27x+2
log(81x)=log(27x+2)(Take log of both sides)
x*(log(81))=(x+2)*(log(27))
x=(
log(27)
log(81)
)*(x+2)
x=0.75*(x+2)
x=0.75x+1.5(Simplify both sides of the equation)
x−0.75x=0.75x+1.5−0.75x(Subtract 0.75x from both sides)
0.25x=1.5
0.25x
0.25
=
1.5
0.25
(Divide both sides by 0.25)
x=6
Enter your answer in the box.
x =
x = 20
Step-by-step explanation:
In this problem, we have a set of vertical angles. We know that vertical angles are congruent, so we just have to set the two expressions equal to each other.
Subtract 3x from both sides.
Add 10 to both sides.
Divide 60 by 3.
x = 20
The percentage of the cards Elin has finished is 72.5%.
Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, Elin has made twenty-nine note cards for her friends. She plans to send out a total of forty cards.
Now, the percentage is
29/40 ×100
= 0.725×100
= 72.5%
Therefore, the percentage of the cards Elin has finished is 72.5%.

Answer:
72.5%
Step-by-step explanation:
(The total number of cards - 40 / Number completed - 29)
1. 40 = 100%
2. Divide both sides of the equation by 40 to get 1 on the right side (40/40 = 1) (100%/40 = 2.5%)
3. multiply both sides of the equation by 29 to find the percentage of cards completed (1*29 = 29 cards finished) (2.5%*29 = 72.5%)
4. Answer: Elin has completed 29 cards which is 72.5% of 40

Step-by-step explanation:
Answer:
Value of 4 in 3492 > Value of 4 in 704
Step-by-step explanation:
The given two numbers are 3492 and 704
Number Thousands Hundreds Tens Ones
3492 3 4 9 2
704 0 7 0 4
In 3492, 4 is at hundreds place and have a value of 4 × 100 = 400
In 704, 4 is at ones place and have a value of 4×1 = 4
Since 400 > 4
Value of 4 in 3492 > Value of 4 in 704
