12x + 3y = 9
3y = -12x + 9
y = (-12/3)x + 9/3
y = -4x + 3

In y = mx + b form, the y int is in the b position...so the y int is 3 or (0,3)

What is 0.8333 forever in a fraction
Nady [450]

There are a couple of different approaches you can use for this. Here's one.

1. Determine how many digits repeat. (There is just one repeating digit.)

2. Call your number x. Multiply x by 10 to the power of the number of digits found in step 1.

x = 0.8\overline{3}\\10^{1}x=8.3\overline{3}

3. Subtract the original number, then solve for x.

10x-x=9x=8.3\overline{3}-0.8\overline{3}=7.5\\\\x=\dfrac{7.5}{9}=\dfrac{5}{6}

_____

If you recognize that 0.333... (repeating) is 1/3, then you know that 0.0333... (repeating) is 1/10×1/3 = 1/30. Add that to 0.8 = 4/5 and you get

... 4/5 + 1/30 = 24/30 + 1/30 = 25/30 = 5/6

Lelechka [254]

Store should sell about 31 bicycle for average price of $135 each bicycle.

Step-by-step explanation:

  • To find bike we need Algebra to solve the equation.
  • when x = 1 , Y = 135 *x
  • When x 2 , Y = 135 *2
  • Formula you could apply to go for break even y = 135*x
  • Bicycle store pays about $4200
  • Algebra used for every business and working to make easy task.
  • It takes about 31 bicycle a month to get into break even.
  • Every store needs break even to not incur lost.
  • Break even point is equilibrium between income and expenses.
