Fed [463]

Answer:

we have to find the quotient and the remainder when (x³ + 5x + 3x² + 5x³ + 3) is divided by (x² + 4x + 2) ♥9 dividend = x² + 4x + 2 using Euclid division lemma, x² + 4x + 2) x² + 5x³ + 3x² + 5x + 3(x³ - 4x² + 19x - 65 x² + 4x² + 2x³ - 4x² + 3x² + 3x² - 4x*-16x³8x² 19x³ + 11x² + 5x 19x³ +76x² + 38x -65x²-33x + 3 -65x²-260x - 130 +227x + 133 Therefore the quotient is x² - 4x + 19x - 65 and remainder is 227x + 133

in september 2007, the average price of gasoline was $2.81 a gallon. This price represented an increase of $2.31 less than twice
hodyreva [135]

Answer:

x = $2.56

Step-by-step explanation:

To solve this, you do the inverse of both operations, which is multiplication and subtraction. The first inverse would be addition, so 2.81 + 2.31 = 5.12. Then, the second inverse would be division, so 5.12 divided by 2 = 2.56. So therefore, x = $2.56 is the correct answer for the price in September 2006.

Passing through (-5,4) with slop -3 ?
PSYCHO15rus [73]

Hey there! :)

Answer:

y = -3x - 11

Step-by-step explanation:

Use the formula y = mx + b to write an equation, where:

y = y-coordinate of point

x = x-coordinate of point

m = the slope

Plug in the known coordinates and slope:

4 = -3(-5) + b

Simplify:

4 = 15 + b

4 - 15 = b

-11 = b

Rewrite the equation:

y = -3x - 11

Use the factor method to find the X intercept for the parable defined by equation: y=-3x^2+12x-9
Marianna [84]

Answer:

x-intercepts are

x=1

x=3

Step-by-step explanation:

we are given equation as

y=-3x^2+12x-9

For finding x-intercept , we can set y=0

and then we can solve for x

y=-3x^2+12x-9=0

we can factor it

-3(x^2-4x+3)=0

-3(x-1)(x-3)=0

now, we can set each terms to 0

and then we can solve for x

(x-1)=0

x=1

(x-3)=0

x=3

So, x-intercepts are

x=1

x=3
