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

pls check this site

Step-by-step explanation:

Answer:

104 m²

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

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

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
