A.
Step-by-step explanation:
Range of a function is the value that we get when a function is solved.
Say, f(x) = y.
We say this "set of x is domain" whereas "set of y is range".
Suppose,
set A = {1,2} & set B = {1,2,3} & f(x) = y
Let,
f(1) = 1, & f(2) = 2.
What we get is that there is no x for 3.
We say this fact by "set A is domain" & "set B is co domain" & set {1,2} (output) is range.

Sylvia buys a case of water that contains 24 bottles and sells x number of bottles to her co-workers. Sam buys a case of water than contains 36 bottles and sells three times as many bottles as Sylvia sold to his co-workers. How many bottles of water did Sylvia sell if they ended up with the same number of bottles of water left over?
Record your answer in the grid below.
Be sure to use the correct place value.
8 points total Show work in order to receive full credit.
7 points correct answer
1 point correct bubbling on grid
Answer:
6
Step-by-step explanation:
Number of water bottles bought by Sylvia = 24
Number of water bottles sold by Sylvia = [tex]x[/tex]
Number of water bottles left with Sylvia = [tex]24-x[/tex]
Number of water bottles bought by Sam = 36
Number of water bottles sold by Sam = Three times as many as bottles as Sylvia sold = [tex]3x[/tex]
Number of water bottles left with Sam = [tex]36-3x[/tex]
It is given that the number of water bottles left with Sylvia and Sam are equal.
i.e.
[tex]24-x=36-3x\\\Rightarrow 2x=12\\\Rightarrow x =\bold{6}[/tex]
So, number of water bottles sold by Sylvia = 6
Tammy purchased a prepaid phone card for $15. Long distance calls cost 18 cents a minute using this card. Tammy used her card only once to make a long
distance call. If the remaining credit on her card is $6.72, how many minutes did her call last?
Answer:
46 minutes
Step-by-step explanation:
Sorry about not answering your question sooner, but here is your answer:
In order to get the answer, we have to subtract the original amount of money on the phone card by the amount left ver after the call:
15 - 6.72 = 8.28
Then, we divide this number by 0.18:
8.28 / 0.18 = 46
So, Tammy's call lasted 46 minutes
Hope this helps :)

Four time the sum of twice a number and six is thirty-two. Find the number
Answer:
4(2x+6)=32 x= 1
Step-by-step explanation:
multiply 4 to 2x and 6= (8x+24)=32
then subtract 24 from 32 = 8
then divide 8 from both sides
8x/8=8/8
x=1
An equation is formed of two equal expressions. The unknown number is 1.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the unknown number be represented by x.
The given statement can be written in the form of an equation as shown below.
Twice of a number → 2xSum of twice a number and six → 2x + 6Four-time the sum of twice a number and six → 4(2x + 6)Four-time the sum of twice a number and six is thirty-two→ 4(2x + 6) = 32
The given equation can be solved as shown below.
4(2x + 6) = 32
Open the parenthesis by multiplying 4 inside the parenthesis,
8x + 24 = 32
Subtract 24 on both sides of the equation,
8x + 24 - 24 = 32 - 24
8x = 8
Divide both sides of the equation by 8,
8x/ 8 = 8/8
x = 1
Hence, the unknown number is 1.

If the pattern indicated below continued, what would be the total number of cubes in the 8th stage of the pattern?
1, 1+4=5, 1+4+9=14
Answer:
The number of cubes in the 8th stage of the pattern is 204
Step-by-step explanation:
Here, we want to calculate simply the 8th term of the pattern
T1 = 1
T2 = 1 + 4 = 1 + 2^2 = 5
T3 = T2 + 3^3 = 5 + 9 = 14
T4 = T3 + 4^2 = 14 + 16 = 30
T5 = T4 + 5^2 = 30 + 25 = 55
T6 = T5 + 6^2 = 55 + 36 = 91
T7 = T6 + 7^2 = 91 + 49 = 140
T8 = T7 + 8^2 = 140 + 64 = 204

Write y=2x^2+24x+47 in vertex form. Also please explain/write the steps thanks.
Answer:
y=(2x^2+24x)+25
y=2x(x^2+12x)+25
y=2x(x^2+12x+36)+25-2x(36)
Y=2x(x+6)^2+25-72
Y=2x(X+6)^2-47
Step-by-step explanation:
sorry it was late
Answer: y=2(x+6)²-5
Step-by-step explanation: First you find the coefficient of x^2, which is 2, then take out 2 as a factor, 24/2 which will equal to 12. After that do 47 divided by 2 if you calculate that it will equal to 23.5. y=2(x²-12+23.5) y =2(x²-12x+23.5)
Next Step: Figure out the coefficient of x. To make it easier,look what is in front of x as you can see it is 12. Then you divide 12/2 which is 6. Then square 6, which is 36. Then you add and subtract 36. To write the first three terms as a square, you do ( x+6)^2. Then do -36 + 23.5 if you calculate that it will get you wil get -12.5 . Now that you have calculated that distribute 2, then do 2 times -12.5 which is -12.5. This is how it shoud look like y=2(x+6)² -12.5.

Given parameters:
Transportation fee = $20
Charge per hour = $30/hr
Unknown:
Inequality representing then number of hours if he has $200 = ?
Solution:
Let the number of hours = x
At most is interpreted in inequality term as <, less than a certain amount;
For x hours,
30x + 20 < 200;
gives the number of hours James have access to the canoe if he has at most $200
