Given the polynomial 6x3 + 4x2 − 6x − 4, what is the value of the coefficient 'k' in the factored form? 6x3 + 4x2 − 6x − 4 = 2(x

anastassius [24]

$6x^3+4x^2-6x-4 =\\ 2(3x^3+2x^2-3x-2) =\\ 2(x^2(3x+2)-1(3x+2))=\\ 2(x^2-1)(3x+2)=2(x+1)(x-1)(3x+2).$

So k=1.

Which expression would be equivalent to: Which expression would be equivalent to: \frac{1+b}{2} - 3(a-1)

IrinaVladis [17]

Answer:

$\frac{1+b}{2} - 3(a-1) = \frac{b- 6a+7}{2}$

Step-by-step explanation:

Given

$\frac{1+b}{2} - 3(a-1)$

Required

An equivalent expression

$\frac{1+b}{2} - 3(a-1)$

Take LCM

$\frac{1+b}{2} - 3(a-1) = \frac{1+b- 2*3(a-1)}{2}$

$\frac{1+b}{2} - 3(a-1) = \frac{1+b- 6(a-1)}{2}$

Open bracket

$\frac{1+b}{2} - 3(a-1) = \frac{1+b- 6a+6}{2}$

Collect like terms

$\frac{1+b}{2} - 3(a-1) = \frac{b- 6a+6+1}{2}$

$\frac{1+b}{2} - 3(a-1) = \frac{b- 6a+7}{2}$

Hence, an equivalent expression is:

$\frac{b- 6a+7}{2}$

Which ordered pies could be points on a line parallel to the line that contains (3,4)and(-2,2) check all that apply

Marina86 [1]

Parallel lines have the same slope. Find the slope of all the lines and compare to see which lines are parallel.

Find slope using the formula y₁ - y₂ / x₁ - x₁.

The first set of coordinates is (3, 4) and (-2, 2). Plug these values in and simplify.

4 - 2 / 3 - (-2)

2 / 3 + 2

2 / 5

Continue plugging and simplifying.

A: (-2, -5) and (-7, -3)

-5 - (-3) / -2 - (-7)

-5 + 3 / -2 + 7

-2 / 5

B: (-1, 1) and (-6, -1)

1 - (-1) / -1 - (-6)

1 + 1 / -1 + 6

2 / 5

C: (0, 0) and (2, 5)

0 - 5 / 0 - 2

-5 / -2

5 / 2

D: (1, 0) and (6, 2)

0 - 2 / 1 - 6

-2 / -5

2 / 5

E: (3, 0) and (8, 2)

0 - 2 / 3 - 8

-2 / -5

2 / 5

All the lines with a slope of 2/5 are parallel to the given line.
