Please help!!! 50 points!!1) Which of the following sets represents the domain of the function shown?
((2,7),(15,13),(21,-4),(24,18))
A) (-4, 2, 7, 13, 15, 18, 21, 24)
B) ((7,2),(13,15),(-4,21),(18,24)
C) (2,15,21,24)
D) (-4,7,13,18)

2) The table shows the outputs y for different inputs x:
Input(x): 3,7,11,15
Output(y): 4,7,8,10

Part A) Do the data in this table represent a function? Justify your answer.
Part B) Compare the data in the table with the relation f(x)=5x-21. Which relation has a greater value when x=11?
Part C) Using the relation in Part B, what is the value of x if f(x)=99?

Answers

Answer 1
Answer: #1,

The domain is all of the x-values.

The x-values of the set are: 2, 15, 21, 24

Your answer is C.


#2,

Part A)
Yes, the data in the table represents a function because each x-value has exactly one y-value. Also, the function passes the vertical line test.

Part B)
f(x) = 5x - 21
f(11) = 5(11) - 21
f(11) = 55 - 21
f(11) = 34

The table has a y-value of 8, when x = 11.

Therefore, f(x) = 5x - 21 has a greater value than the table when x = 11

Part C)
f(x) = 99
f(x) = 5x - 21

5x - 21 = 99
5x = 120
x = 24

The value of x is 24.

If I am asked to write 5 to the second power times 3 to the 5th power in factor form, how would I do that?

Answers

so 5 to the second power means 5 times itself twice or 5*5 which is noted as 5^2'


times 3 to the fifth power or 3 times itself 5 times or 3*3*3*3*3 which is noted as 3^5


so (5^2)(3^5) is the answer (6075 is the expanded form)
5×itself 2x witch would be 25
and 3× itself 5× so this is what it look like 3•3•3•3•3 witch it would be 243

and then 25×243= 6075

tiffany plans to use $275 she earned from a summer job to buy some new clothes for school. she found several items she likes but is trying to decide if she has enough money to buy all of them . she wants to buy three pairs of jeans for $42 each and five shirts with an average cost of $27 per shirt. she will have to pay 6% sales tax

Answers

Answer:

Total amount Tiffany has to pay = $276.66

Step-by-step explanation:

Cost of one pair of jeans = $42

Cost of three pairs = 3(42) = 126

Cost of one shirt = 27

Cost of five shirts = 5(27) = 135

Total amount Tiffany has to pay = 126 + 135 = 261.

Sales tax = 6%

6% of 261 = 0.06(261) = 15.66

So, total amount including sales tax Tiffany has to pay = 261 + 15.66 = 276.66.

The total cost without tax would be $261, sales tax would be $15.66, if we add them add the answer would be $276.66.
