6x^3-1x^2+1/2x+1

Multiply 1 times x^2 = x^2=6x^3-x^2+1/2x+1

Use the rational root theorem

(2x-1)(3x²-2x+1)/2x+1

Cancel the common factor: 2x+1

3x²-2x+1

1.) Set it up like a long division problem.
(2x + 1)/(6x^3 - 1x^2 + 1)

2.) How many times does 2x go into 6x^3? (just look at the first term for long division polynomials). It goes in 3x^2 times.

3.) Do the same thing you would in a normal long division problem. Because you subtract and bring down 3x^2(2x+1), you multiply -3x^2 instead of 3x^2. You will add that.

4.) Distribute -3x^2(2x+1)
-6x^3 - 3x^2

5.) Add -6x^3 - 3x^2 to 6x^3 - 1x^2

6.) You get -4x^2

7.) Repeat. How many times does (2x + 1) go into -4x^2?

8.) -2x times. Multiply NEGATIVE ONE to it as you are subtracting it (even if it starts out negative), add it, repeat until you run out of terms.

9.) Any remainders should be the remainder over (2x + 1)

You should get <span>3x²-2x+1</span>

Hope this helps, ask for any specifications so I can edit this :)

Answer: 6x + 8y =1,245

Step-by-step explanation:

Hi, to answer this question we have to write an equation for each person:

Jack = The total cost (650) must be equal to the product of the number of shirts he bought (2) and the price per shirt (x); plus the product of the number of pair of jeans he bought (5) and the price per jean (y).

2 x+ 5 y=650

Dylan = The total cost (595) must be equal to the product of the number of shirts he bought (4) and the price per shirt (x); plus the product of the number of pair of jeans he bought (3) and the price per jean (y).

4x+3y = 595

Vertical addition:

2 x+ 5 y=650

+

4x+3y = 595

_________

6x + 8y =1,245

Check all of the ordered pairs that satisfy the equation below.
Georgia [21]
A. 21*(2/3) = 14 -----> not 3/2 (X
B. 7*(2/3) = 14/3 ----> not 14 (X
C. 21*(2/3) = 14 -----> equal 14 (O
D. 28*(2/3) = 56/4 -> not 42 (X
E. 42*(2/3) = 28 ----> equal 28 (O
F. 14*(2/3) = 28/3 --> not 21 (X

so the answer is C and E

➷ Find the multiplier:

28/100 = 0.28

1 - 0.28 = 0.72

Multiply the total amount by this multiplier:

40,000 x 0.72 = 28,800

She will make $28,800
