how to find the domain and range of y=|x| ?​

Answers

D: (-inf, +inf)
R: [0, +inf)

That equation is the parent function of the absolute value function. To find domain, move from left to right. Look at the x-values and where the graph goes. To find range, move from bottom to top and look at the y-values. I recommend using a stick/pencil and moving it along the graph.

MONEY PRIZE FOR THE FIRST PERSON TO GET THIS RIGHT AT THE END OF THE PROBLEM LIST METHOD OF ONLINE PAYMENT YOU WANT!
Situation: You love to knit sweaters and you want to start a small business to make money from your talent. You want to do the math first to find out how long it will take for you to make a profit. You must pay a fixed fee of $90.00 to start the company up plus $15.00 for each sweater to pay for the yarn. You want to charge $30.00 for each sweater that you sell.

1. Write an equation for the cost of the company
Choose and define your variables in words:
x:
Equation: y:

2. Write an equation for the money made, INCOME (NOT PROFIT ALL INCOME), selling sweaters
Choose and define your variables in words:
x:
Equation: y:

After you have your equations:
-Find the cost and income when you sell 2 sweaters. (You should have two different answers because you had two different equations one for the INCOME and one for the COST!)

Hints: REMEMBER X is your independent variable so look at the independent number or thing about the problem and write it for x: . Also REMEMBER Y is your dependent variable so whatever your x is y will depend on it if X changes Y also changes look at the problem and ask yourself "What has an effect on what? and "What is effected by what?" This will help you answer the problem.

Answers

Answer:

1. y = 90x

x: the amount of companies to start

y: The total amount it will cost.

2. y = 30x

y: the total income

x: the amount of sweaters being sold.

The answer to the last question(I think would be):

cost:  $30

income: $60

as:

equation to find cost = y = -15x

equation to find income = y = 30x

[tex](-1{2}{3} )x^{3}[/tex]

Answers

After talking with you here are two different options I think you are trying to ask:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If you are talking about: [tex](\frac{-12}{3}) ^{3}[/tex]

Answer: -62

Explanation:

PEMDAS tells us we need to do the exponent first:

-12³ = (-12)³ = -1728

The parentheses are important so you cube the negative sign as well!

3³ = 27

-1728 / 27 = -62

                           [tex](\frac{-12}{3}) ^{3}[/tex] simplified is -62

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If you are talking about (-1[tex]\frac{2}{3}[/tex])³

Answer: -[tex]\frac{125}{27}[/tex]

Explanation:

First, let us turn -1 and two thirds into a mixed number:

Ignoring the negative for now, we can 1 times 3 is 3. 3 plus 2 is 5. 5/3 is 5/3. Adding in the negative we get [tex]-\frac{5}{3}[/tex]

To cube it we must do:

([tex]-\frac{5}{3}[/tex])([tex]-\frac{5}{3}[/tex])([tex]-\frac{5}{3}[/tex])

3 times 3 (9) times 3 is 27

5 times 5 (25) times 5 is 125

So we have 125/27

For the negative, we have three - - -

Two cancel each other out, and we are left with one (-) so our answer is negative

                           (-1[tex]\frac{2}{3}[/tex])³ simplifed is -[tex]\frac{125}{27}[/tex]

Solve the simultaneous equations.
x + 2y = 9
5x – y = – 10

Answers

Answer:

(- 1, 5 )

Step-by-step explanation:

Given the 2 equations

x + 2y = 9 → (1)

5x - y = - 10 → (2)

Multiplying (2) by 2 and adding to (1) will eliminate the y- term

10x - 2y = - 20 → (3)

Add (1) and (3) term by term to eliminate y

11x + 0 = - 11

11x = - 11 ( divide both sides by 11 )

x = - 1

Substitute x = - 1 into either of the 2 equations and solve for y

Substituting into (1)

- 1 + 2y = 9 ( add 1 to both sides )

2y = 10 ( divide both sides by 2 )

y = 5

solution is (- 1, 5 )

x + 2y = 9 x + 2y = 9

=====》

5x - y = - 10 (×2) 10x - 2y = - 20

+____________

11x + 0 = - 11

11x = - 11

x = - 1

Thus :

- 1 + 2y = 9

Add both sides 1

2y - 1 + 1 = 9 + 1

2y = 10

Divide both sides by 2

2y ÷ 2 = 10 ÷ 2

y = 5

Step-by-step explanation:

There is a 1 m sidewalk around the garden

Then length = 30 + 1 + 1 = 32 m

and width = 20 + 1 + 1 = 22 m

Area = 32 × 22 = 704 m²

Area of garden = 30 × 20 = 600 m²

Area of sidewalk = 704 - 600 = 104 m²

What is the logarithmic formula 10000= 625/8*2^t ?

Answers

9514 1404 393

Answer:

     log(128) = t·log(2)

Step-by-step explanation:

You can take logarithms the way the formula is, or you can simplify it first.

As is

  log(10000) = log(625) -log(8) +t·log(2)

__

Simplified

  8·10000/625 = 2^t . . . . . multiply by 8/625

  128 = 2^t

  log(128) = t·log(2)

_____

Solution:

  t = log(128)/log(2) = 7
