Select all polynomials that are divisible by (x-1).

goldenfox [79]

Answer:

The answer to your question is below

Step-by-step explanation:

*A(x)=3x³ + 2x² - x This polynomial is not divisible by (x - 1)

Factor completely 3x(x + 1)(3x - 1)

*B(x)=5x³ - 4x² - x This polynomial is divisible by (x - 1)

factor completely 3x(x - 1)(5x + 1)

*C(x)=2x³ - 3x² + 2x - 1 This polynomial is divisible by (x - 1)

Synthetic division 2 - 3 + 2 -1 1

Point P is located at (−2, 7), and point R is located at (1, 0). Find the y value for the point Q that is located two over three

irinina [24]

Answer:

7/3

Step-by-step explanation:

The distances have the ratio ...

(Q -P) = (2/3)(R -P)

Q = P +(2/3)R -(2/3)P = (2R +P)/3

Qy = (2Ry +Py)/3 = (2·0 +7)/3 = 7/3

Chloe is 200 miles from Los Angeles and she at a constant speed of 55 miles. You just do 200/55 and that’s how long Chloe drives in a hour.

Help me it’s urgent

Ket [755]

Answer:

$a_1 = -\dfrac{3}{4}$

Step-by-step explanation:

$a_1 \times r = a_2$

$a_1 \times r^2 = a_3$

$a_1 \times r^3 = a_4$

...

$a_1 \times r^8 = a_9$

$\dfrac{a_9}{a_4} = \dfrac{a_1 \times r^8}{a_1 \times r^3} = \dfrac{-196}{6}$

$r^5 = -32$

$r = -2$

$a_1 \times r^3 = a_4$

$a_1 \times (-2)^3 = 6$

$a_1 = \dfrac{6}{-8}$

$a_1 = -\dfrac{3}{4}$

What is the equation of the line that passes through the point (−4,−8) and has an undefined slope?

Masja [62]

Answer:

x = -4

Step-by-step explanation:

An undefined slope would look like a vertical line, up and down. This is shown using an x equals equation instead of a y equals equation.

Since the line goes vertically, you only need to look at the x-value to make the equation, since after doing x = -4 the line would keep going down until it touched (-4, -8).

The line would touch everything in the y-value but stay at x = -4.

Therefore the answer to this problem is x = -4. I've attached a picture (from desmos) showing what the graph of x = -4 would look like and how it touches the point (-4, -8).
