A. (x-2)(x+1)(x-1)
B. (x-2)(x-2)(x-1)
C. (x-4)(x+1)(x-1)
D. 2(x+2)(x+1)(x-1)
Answers
It is true that the value -2 is a lower bound for the zeros of the function f(x) = 4x³ - 12x² - x + 15
The polynomial as a product of linear factors is d. 2(x+2)(x+1)(x-1)
How to determine the true statement
From the question, we have the following parameters that can be used in our computation:
f(x) = 4x³ - 12x² - x + 15
Also, we have
x =-2
Calculate f(-2)
f(-2) = 4(-2)³ - 12(-2)² - (-2) + 15
f(-2) = 4 * -8 - 12 * 4 + 2 + 15
f(-2) = -32 - 48 + 2 + 15
f(-2) = -63
The above value is negative
This means that -2 is a lower bound for the zeros of the function.
Expressing the polynomial as a product of linear factors.
Here, we have
f(x) = 2x³ + 4x² - 2x - 4
Factorize in 2's
So, we have
f(x) = 2x²(x + 2) - 2(x + 2)
This can be expressed as
f(x) = (2x² - 2)(x + 2)
Factor out 2
f(x) = 2(x² - 1)(x + 2)
Express as difference of two squares
f(x) = 2(x - 1)(x + 1)(x + 2)
Hence, the polynomial as a product of linear factors is d. 2(x+2)(x+1)(x-1)
Point V lies between points U and W on UW.
If UW = 9x – 9, what is UW in units?
5 units
6 units
30 units
36 units
Answers
hope this helps :)))))
Answer: The correct option is (D) 36 units.
Step-by-step explanation: Given that point V lies between points U and W on UW, where
[tex]UV=2x-4,~~VW=4x+10~~~\textup{and}~~~UW=9x-9.[/tex]
We are to find the length of UW in units.
Since point V lies on the line segment UW, so we must have
[tex]UV+VW=UW\\\\\Rightarrow (2x-4)+(4x+10)=9x-9\\\\\Rightarrow 6x+6=9x-9\\\\\Rightarrow 9x-6x=6+9\\\\\Rightarrow 3x=15\\\\\Rightarrow x=5.[/tex]
Therefore, the length of UW is
[tex]UW=9x-9=9\times5-9=45-9=36~\textup{units}.[/tex]
Thus, the length of UW is 36 units.
Option (D) is correct.

A rate that describes how much smaller or larger the scale drawing is than then real object
Answers
The scale factor is a ratio that describes the relationship between the dimensions of a scale drawing and the real object that it represents. A larger scale factor indicates a greater level of detail in the drawing, while a smaller scale factor depicts less detail and a larger area.
Explanation:The rate that describes how much smaller or larger the scale drawing is than the real object is known as the scale factor. A scale factor is a ratio that compares the dimensions of the actual object to the dimensions of a scale drawing or model. For example, a scale factor may be written as 1/200, meaning that the real object is 200 times larger than the scale drawing.
Scale can also be described using terms such as 'small' or 'large' scale. These terms relate to the level of detail a map shows; a large-scale map, with a representative fraction of 1:1,000, shows more detail and less area whereas a small-scale map, with a representative fraction of 1:1,000,000, shows less detail and more area.
Understanding these concepts is essential when interpreting maps and drawings as they communicate the level of zoom and detail. Remember, scale refers to a ratio and not the physical size of the map or drawing itself.

Lizabeth remembers the poverty of her childhood hometown but also the marigolds in Miss Lottie's yard.
Explanation:
The short story "Marigolds" by Eugenia Collier is a story of a little girl's childhood experience. In the story, Lizabeth talks of how her community is impoverished, "—the brown, crumbly dust of late summer—arid, sterile dust that gets into the eyes and makes them water, gets into the throat and between the toes of bare brown feet". But despite the background image of poverty all around her, she could also remember "a brilliant splash of sunny yellow against the dust—Miss Lottie’s marigolds". Through her remembering of the marigolds amidst the poverty of her childhood hometown, Lizabeth develops the theme of beauty appreciated even in the worse circumstances.

Explanation:
__________________________________________
Basically, we can reduce the question to:
__________________________________________
What is " ¼" of "2 ⅔ kg" ?
_______________________________
→ (¼ * 2 ⅔) kg ; simplify the amount in "parentheses" ; & keep the units of "kg" (kilograms) ;
______________________________________________
Write " 2 ⅔ " as an "improper fraction" ;
→ To do so, multiply the "3" in the "denominator" (from the fraction, " ⅔ ") ;
by the "2" (from the whole number).
→ 3 * 2 = 6 .
_________________________________________
→ Then, take this value; in our case, "6" ; and the number "2" (from the "2" in the "numerator" (from the fraction portion, " ⅔ ").
→ 6 + 2 = 8 .
__________________________________________
→ Then, take this value, and write is as the "numerator" over a "new fraction" ; this "new fraction" is the: "improper fraction" . The "denominator" of this "new fraction" (i.e. "improper fraction") ; is the number from the "denominator" of the fraction portion of our [originally written "mixed number" ; which in our case is: "3" (from the fraction portion, " ⅔ ") .
___________________________________________
→ So, our mixed number, " 2 ⅔ " , can be written in the "improper fraction form" ; which is: " ⁸/₃ " .
___________________________________________
→ Put simply: " 2 ⅔ = [ (3*2) + 2 ] / 3 = (6 + 2) / 3 = 8/3 ; or, " ⁸/₃ " .
___________________________________________
→ We have: "(¼ * 2 ⅔) kg " .
→ Replace the: " 2 ⅔ " value with: " ⁸/₃ " ; to more easily simplify the expression in "parentheses" ; & to more easily solve the problem ;
__________________________________________________
→ "(¼ * 2 ⅔) = [tex] \frac{1}{4} [/tex]*[tex] \frac{8}{3} [/tex] " ;
= ? ;
___________________________________________________
→ We have: " [tex] \frac{1}{4} [/tex]*[tex] \frac{8}{3} [/tex] " ;
→ The "4" can be 'canceled out' to a "1" ;
and the "8" can be 'canceled out', and changed to a "2" ;
→ since: "(8÷4=2)" ; and since: "(4÷4=1)" .
___________________________________________________
So now; we have: " [tex] \frac{1}{1} [/tex] * [tex] \frac{2}{3} [/tex] " ;
___________________________________________________
→ The " [tex] \frac{1}{1} [/tex] " can be eliminated;
→ since: "(1÷1=1)" ;
→ {Note that any value, divided by "1", is equal that same value ;
& that "any non-zero value", divided by "that same value", is equal to "1" .
______________________________________________________
→ As such: " [tex] \frac{1}{1} [/tex] " = {1÷1} = 1 ;
& this value, which is "1", multiplied by [the other expression], will be equal to that other expression;
since:
______________________________________________________
→ [the other expression, which is a non-zero value] , multiplied by "1", is equal to [the SAME other expression, which is a non-zero value].
______________________________________________________
→ As such, we can completely eliminate the: " [tex] \frac{1}{1} [/tex] " ;
and we are left with: " ⅔ " . The units are "kg" .
So; the answer is: " ⅔ kg" ;
Note: " ⅔ " = 2÷3 = 0.666666666666667 ;
____________________________________________
So; the answer is: " ⅔ kg" ; or, write as: 0.6667 kg .

6a - 10 = 3a + 17 please explain how you got your answer
Answers
Put similar things together
First step is to subtract 3a from both sides
3a - 10 = 17
Second step is to add 10 to both sides
3a = 27
Third step is to divide both sides by 3
a = 9
That's the answer.
To solve the equation 6a - 10 = 3a + 17, we first move all 'a' terms to one side and constants to the other, then simplify and solve for 'a', resulting in a = 9.
The student has asked to solve the equation 6a - 10 = 3a + 17. To find the value of 'a', we need to consolidate all the 'a' terms on one side and the constants on the other side. Here's the solution step-by-step:
Subtract '3a' from both sides of the equation to get '6a - 3a - 10 = 17'.
Simplify the left side to get '3a - 10 = 17'.
Add '10' to both sides to isolate the 'a' term and get '3a = 17 + 10'.
Simplify the right side to get '3a = 27'.
Divide both sides by '3' to solve for 'a', getting 'a = 27 / 3'.
Finally, 'a = 9'.
The correct answer is a = 9.

What is the equation of a line that passes through the point (9, −3) and is parallel to the line whose equation is 2x−3y=6 ?
Enter your answer in the box
Answers
-3y = -2x + 6
y = 2/3x - 2....the slope here is 2/3. A parallel line will have the same slope
y = mx + b
slope(m) = 2/3
(9,-3)...x = 9 and y = -3
now we sub and find b, the y int
-3 = 2/3(9) + b
-3 = 6 + b
-3 - 6 = b
-9 = b
so ur parallel equation is : y = 2/3x - 9 <== or 2x -3y = 27
The equation of the line, in slope-intercept form, that is parallel to 2x - 3y = 6 and passes through (9, -3) is: [tex]\mathbf{y = \frac{2}{3}x - 9}[/tex]
Given:
Points the line passes through, (9, -3)
The equation of the line it is parallel to: 2x - 3y = 6
Note:
Parallel lines have the same slope valueEquation of a line in slope-intercept form is: y = mx + b. (m is slope; b is y-intercept)Point-slope form is; y - b = m(x - a)First, rewrite 2x - 3y = 6 in slope-intercept form to determine its slope.
[tex]2x - 3y = 6\\\\-3y = -2x + 6\\\\y = \frac{2}{3}x - 2[/tex]
The slope of 2x - 3y = 6 is therefore 2/3.Thus, the slope of the line that passes through (9, -3) is also 2/3.
Write the equation of the line in point-slope form:
Substitute m = 2/3, and (a, b) = (9, -3) into y - b = m(x - a)
Thus:[tex]y - (-3) = \frac{2}{3}(x - 9)\\\\y + 3 = \frac{2}{3}(x - 9)[/tex]
Rewrite in slope-intercept form[tex]y + 3 = \frac{2}{3}(x - 9)\\\\y + 3 = \frac{2}{3}x -\frac{2}{3}(9)\\\\y + 3 = \frac{2}{3}x - 6\\\\y = \frac{2}{3}x - 6 - 3\\\\\mathbf{y = \frac{2}{3}x - 9}[/tex]
Therefore, the equation of the line, in slope-intercept form, that is parallel to 2x - 3y = 6 and passes through (9, -3) is: [tex]\mathbf{y = \frac{2}{3}x - 9}[/tex]

In the figure, BC and AD are line segments. What is the sum of x and y?
Answers
x = 54
when added, they equal (62 + 54) = 116
Answer:
The correct option is 2.
Step-by-step explanation:
Given information: BC and AD are line segments.
According to the angle sum property, the sum of interior angles of a triangle is 180°.
In triangle DOC,
[tex]\angle C+\angle COD+\angle D=180^{\circ}[/tex]
[tex]y+64^{\circ}+54^{\circ}=180^{\circ}[/tex]
[tex]y+118^{\circ}=180^{\circ}[/tex]
[tex]y=180^{\circ}-118^{\circ}[/tex]
[tex]y=62^{\circ}[/tex]
The value of y is 62°.
If two lines intersect each other then vertical opposite angles are equal.
[tex]\angle COD=\angle AOB=64^{\circ}[/tex]
In triangle AOB,
[tex]\angle A+\angle AOB+\angle B=180^{\circ}[/tex]
[tex]x+64^{\circ}+62^{\circ}=180^{\circ}[/tex]
[tex]x+126^{\circ}=180^{\circ}[/tex]
[tex]x=180^{\circ}-126^{\circ}[/tex]
[tex]x=54^{\circ}[/tex]
The value of x is 54°.
The sum of x and y is
[tex]54^{\circ}+62^{\circ}=116^{\circ}[/tex]
The sum of x and y is 116°. Therefore the correct option is 2.
