Please Help!!!!Which Of The Following Represents A Function???

Answers

Answer 1

Answer:

A

Step-by-step explanation:

A represents a funtion becasue none of the x (input) values are repeating.

Reasoning:

In B the x value of -1 is repeating

In C the x value of 3 is repeating

In D the x value of -1 is repeating

Answer 2

The graph given in the problem shows a function. The correct option is (D).

What is a function?

A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.

The given options are examined one by one as follows,

(A) The mapping of the sets can be written in the form of ordered pair as,

{(-4, 5), (9, 7), (13, 3),(-7, 5)}

Since, fortwo different values of domain there is only one value in the range, it does not represent a function.

(B) From the given table it is observed that y = 1 for x = -5 and x = -1.

Thus, it does not represent a function.

(C) The given ordered pair is {(0, 1), (3, 2),(-8, 3), (-7, 2), (3, 4)}

The second element 2 of the ordered pair is for two values of first elements.

Thus, it does not represent a function.

(D) The ordered pair for the given graph is as below,

{(-1, 1), (1, 4), (-3, -2), (-1, -5)}

Since no values of the range have two values in the domain, it represents a function.

Hence, the graph shown in the problem represents a function.

6q − 18 > 5q − 23 solve

Answers

Answer:

6q-2=66.1

Step-by-step explanation:

Answer:

q > -5

Step-by-step explanation:

start by solving this like a regular inequality

6q − 18 > 5q − 23 you would subtract 5q from 5q (to cancel out) then from 6q

q - 18 > -23 now add 18 to -18 (to cancel out) then add it to -23

q > -5

Jackson and his grandfather constructed a model for a birdhouse. Many of their neighbors offered to buy the birdhouses.

Jackson decided that building birdhouses could help him earn money for his summer camp, but he is not sure how long it

will take him to finish all of the requests for birdhouses. If Jackson can build birdhouses in hours, write an equation

that will allow Jackson to calculate the time it will take him to build any given number of birdhouses, assuming he works

at a constant rate.

a. Write an equation that you could use to find out how long it will take him to build any number of birdhouses.​

Answers

Answer to question A: The equation should be Y because the birdhouses divided by the amount of hours  Y= 7/5x

Answer to 1 is 40 Hours which that makes 56 bird houses

Answer to 2 is 35 Birdhouses which that makes 25 hours

If you bought a stock last year for a price of $33, and it has gone down 4% since then, how much is the stock worth now, to the nearest cent?

PLZ HELP I WILL GIVE BRAINLIEST!!

Answers

Answer:

The answer should be $31.68

Step-by-step explanation:

Well to find 4% lower we have to find 4% of 33. To find that we have to do 33 X 0.04 and get 1.32. Now we have to subtract 1.32 from 33 and you get 31.68.

Answer:

See below.

Step-by-step explanation:

First, divide the percent to find the decimal form.

[tex]\frac{4}{100} =0.04[/tex]

Then, multiply the percentage by the total.

[tex]33 *0.04=1.32[/tex]

Last, subtract it by the total.

[tex]33-1.32=31.68[/tex]

Answer: [tex]31.68[/tex]
