answer:

c. 2 1/6x + 2 1/6y

step-by-step explanation:

3x−1/2y+2 2/3y−5/6x

  • solve this to see what you get

3x−1/2y+2 2/3y−5/6x

  • combine like terms
  • this will make it easier to solve (its a part of solving this)

3x−1/2y+2 2/3y−5/6x

  • lets look at the like terms here

−1/2y and + 2 2/3y

3x and - 5/6x

  • now combine them

−1/2y + 2 2/3y = 13/6y

3x - 5/6x = 13/6x

  • now look at the original equation and put them together

= 13/6x + 13/6y

= 2 1/6x + 2 1/6y (simplified)

  • now that we have that simply look at the choices and see which one matches what we got

Prove (x+y)^2=x^2+2xy+y^2
Scrat [10]
Rules of exponents and the distributive property apply.
  (x+y)² = (x+y)·(x+y) . . . . . meaning of exponent of 2
  = x·(x+y) +y·(x+y) . . . . . . . distributive property
  = x·x +x·y +y·x +y·y . . . . . distributive property
  = x² +x·y +x·y +y² . . . . . . meaning of exponent of 2, commutative property of multiplication
  = x² +(1+1)·x·y +y² . . . . . . distributive property
  = x²+2xy+y² . . . . . . . . . the desired form
Thus
  (x+y)² = x²+2xy+y²

Korey is planning to open a comic book store. His store will cost $12,500 to open and will come with a $8,000 total annual opera
Phoenix [80]

Answer:

c. Korey will see an overall profit in his third year of business

Step-by-step explanation:

His cost for first year

= 12500+8000

=$ 20500

Profit first year= $12000

Net Profit first year= -$8500

Second year cost= $8000

Profit second year

= 12000+12000(0.06)

= 12000+720

=$ 12720

Net profit second year = -8500+12720-8000

= -3780

Third year

Cost = $8000

Profit= 12720+12720(0.06)

Profit=$13483.2

Net profit= 13483.2-8000-3780

Net profit= $1703.2
