can anybody teach me about functions domains and range?

Answers

Answer 1
Functions are graphs that do not have repeating x-values. The domain of a function are the x-values and the range are the y-values in a function
Answer 2
To make something a function the x cannot share multiple Ys(the vertical line test) but the y can share as many Xs
For example:
(1,3) (1,-6) would not be a function but...
(1,3) (2,6) would be

The domain is the x value. In a table it will almost always appear on the left side.

The range is the y value. In a table it will almost always appear on the right side.

During a sale, every item in a store is 80% of its regular price.

2. During a sale, every item in a store is 80% of its regular price. The regular prices of five items are shown here. Find the sale price of each item.


P.S. For the 2nd question see the file.

P.P.S. WILL GIVE BRAINLIEST!

Answers

Answer:

For #1 the answer is $2

Step-by-step explanation:

This is because 80% of 10 is 8, so then you subtract that and get 2. For #2 the answer to item 1 is $0.8, item 2 is $3.2, item 3 is $8, item 4 is $44, and item 5 is $96

Answer/Step-by-step explanation:

During a sale, every item in a store is 80% of its regular price

[1] if a regular T-shirt is $10, what is its sale price?

80% x 10 = 8

10 - 8 = 2.

Hence if a regular T-shirt is $10, the sale price will be $2.

[2] The regular prices of five items are shown here. Find the sale price of each item.

Item 1:   1x80%=0.8

Item 2: 4x80%=3.20

Item 3: 10x80%=8

Item 4: 55x80%=44

Item 5: 120x80%=96

Heya!

So the key is at the top. What I mean by the Key is a=1 b=2 c=3 d=4 e=5 and f=0. You use those numbers and plug them into the associated letters in the problems below. For example, question one with the numbers in it would be, (I might be wrong on this, I apologize)

[tex] \frac{0 + 3^{2} - 2 }{0 - 3} [/tex]

You would then solve the equation, and whatever answer you get for that equation would go with the corresponding numbers and letters on the left.

So for example, if your answer to the first one for example is 7, you would type A. You would then do the same for question 2, 3, and 4, which should reveal the four letter code for you to continue :))

Answers

Answer:

n=3/5

Step-by-step explanation:

3n−3+10+2n=10

Step 1: Simplify both sides of the equation.

3n−3+10+2n=10

3n+−3+10+2n=10

(3n+2n)+(−3+10)=10(Combine Like Terms)

5n+7=10

5n+7=10

Step 2: Subtract 7 from both sides.

5n+7−7=10−7

5n=3

Step 3: Divide both sides by 5.

5n /5

= 3 /5

n= 3 /5

Answer:

n=3/5

Step-by-step explanation:

3n-3+10+2n=10  Combine like terms.

5n+7=10              Subtract 7 from both sides.

    -7  -7

5n=3                    Divide both sides by 5.

/5  /5

n=3/5

The length of a rectangular fenced enclosure is 12 feet more than the width

If farmer Dan has 100 feet of fencing, find the dimensions of the rectangle with the largest perimeter that can be created using 100 feet of fencing.

Answers

Answer:

length = 31 ft

width = 19ft

largest perimeter = 100 ft

Step-by-step explanation:

Let’s say the variable is x, if you draw a rectangle, you’d lable the length as 12+x (because the length is 12 ft longer than the width) and you’d lable the width as x.

Then you’d multply both terms by 2 (and add them up):

2(12+x) + 2(x)

Once you distribute and add...

24 + 2x + 2x

24 + 4x

Then you’d set that equal to 100, since that’s the amount of fencing Dan has:

24 + 4x = 100

Subtract 24 on both sides:

4x = 76

Divide by 4 on both sides:

x = 19

Then you found the width, now to find the length, just add x to 12 (which equals to 31).

Add all the sides up and it equals to 100, which is the largest perimeter than can be created using 100 ft of fencing.

Hope this helped :)
