Answer: The correct answer is true

Step-by-step explanation:

  -8x + 35y - 23  =   -1 • (8x - 35y + 23) 

The solution for (w) is  W= 4k-2b / -5, corresponding to option A.

To solve the equation [tex]\(k = \frac{2b - 5w}{3k}\)[/tex] for (w), we follow these steps:

1. Isolate the term containing (w):

  Multiply both sides of the equation by (3k) to eliminate the denominator:

[tex]\[3k^2 = 2b - 5w\][/tex]

2. Isolate (w):

  Subtract \(2b\) from both sides of the equation:

[tex]\[3k^2 - 2b = -5w\][/tex]

3. Divide both sides by (-5):

  Divide both sides of the equation by (-5) to isolate (w):

[tex]\[w = \frac{3k^2 - 2b}{-5}\][/tex]

Now, let's summarize the answer:

The solution for (w) is given by option:

[tex]\[\boxed{\text{(A) } w = \frac{4k - 2b}{-5}}\][/tex]

Answer:

The given expression is irrational because one factor is irrational

Step-by-step explanation:

Given the expression

[tex](\sqrt{576})(\sqrt{684})[/tex]

we have to find that the product is rational or irrational.

[tex]\sqrt{576}=\sqrt{26\times 26}=26[/tex]

[tex]\sqrt{684}=\sqrt{2 \times 2 \times 3 \times 3 \times 19}=2\times 3\sqrt{19}=6\sqrt{19}[/tex]

[tex]\text{The square root of 19 is irrational }[/tex]

[tex]\text{The square root of 684 is irrational }[/tex]

Hence, the first factor of the expression is rational and the second factor is irrational therefore the product is irrational.

∴ option 3 is correct

The given expression is irrational because one factor is irrational

Determining the proper option, acquiring evidence, and exploring various options are all steps in the decision-making process.

Jorge wants to find the most popular way for teens to volunteer in the community. He cannot decide between two methods.

Option 1: He will ask every fifth person on each English class roster. This is a biased one because the best one can be skipped.

Option 2: He will attend a walkathon to ask teen participants about the ways they volunteer. Because all the volunteers participated that can be observed.

we are given

radius=r=12m

height=h=9m

now, we can use formula of volume of cylinder

[tex] V=\pi r^2 h [/tex]

now, we can plug values

and we get

[tex] V=\pi (12)^2 *9 [/tex]

we get

[tex] V=1296 \pi m^3 [/tex]

so, the exact volume of the cylinder is [tex] 1296 \pi m^3 [/tex]..........Answer

Answer:

(D)

Step-by-step explanation:

It is given that a cylinder has a radius of 12 m and a height of 9 m.  Then,

Volume of the cylinder is given as:

[tex]V={\pi}r^{2}h[/tex]

⇒[tex]V={\pi}(12)^2(9)[/tex]

⇒[tex]V={\pi}(144)(9)[/tex]

⇒[tex]V=1296{\pi}m^3[/tex]

Therefore, the volume of the cylinder is [tex]1296{\pi}m^3[/tex].

Thus, Option D is correct.

Step-by-step explanation:

The required proportion that predicts the number of jazz songs he has stored on his MP3 player is 3/20 = x / 2000.

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

Here,
From the table number of Jazz songs played = 6
Total song played = 40

Total number of songs in mp3 player = 2000
Number of jazz songs in mp 3 player
6/40 = x /2000
3/20 = x / 2000

Thus, the required proportion that predicts the number of jazz songs he has stored on his MP3 player is 3/20 = x / 2000.

Step-by-step explanation:

By Transitive property ∠XYZ = ∠WYT.

The word "transitive" refers to movement. The transitive property of equality is a property that applies when there are three quantities, a, b, and c, and if a is connected to b and b is related to c by the same rule, then a and c are related to each other by the same rule.

Let's think about the numbers a = b and b = c. Because equality has the symmetric characteristic, writing a = b is equivalent to writing b = a. It follows that b = a and b = c. A must equal c and b since the amount b cannot be equal to two separate quantities.

Given:

∠XYZ ≅ ∠​AOB and ∠​AOB ≅ ∠​WYT

As per the Transitive Property

<X = <Y

and ∠Y = ∠X,

then ∠X = ∠Z.

Similarly,

∠XYZ = ∠AOB

and ∠AOB = ∠WYT,

then ∠XYZ = ∠WYT.

Hence, by Transitive property ∠XYZ = ∠WYT.

Step-by-step explanation:

Final answer:

To find the slope-intercept form of a line with a given slope of -5/2 that passes through the point (8, -1), we use the point-slope form and then rearrange to get the final equation: y = (-5/2)x + 19.

Explanation:

To write the equation of a line in slope-intercept form (which is y = mx + b), we need to know the slope (m) of the line and the y-intercept (b). In this case, we are given the slope of the line as -5/2 and a point through which the line passes, which is (8, -1). Using the point-slope form, which is y - y1 = m(x - x1) where (x1, y1) is the given point and m is the slope, we can substitute the given slope and the coordinates of the given point to derive the slope-intercept form.

The equation starts with y - (-1) = (-5/2)(x - 8). Simplifying the equation, we get:

y + 1 = (-5/2)x + (5/2)*8

y = (-5/2)x + 20 - 1

y = (-5/2)x + 19

So, the equation of the line in slope-intercept form is y = (-5/2)x + 19.

To write an equation in slope-intercept form, substitute the given values of the slope and a point on the line into the equation. The equation of the line passing through the point (8, -1) with a slope of -5/2 is y = -5/2x + 19.

To write an equation in slope-intercept form, we need to use the given slope and the coordinates of the point through which the line passes. The slope-intercept form is y = mx + b, where m represents the slope and b represents the y-intercept. We're given that the slope of the line is -5/2, so we can substitute this value for m. We're also given that the line passes through the point (8, -1), so we can substitute these coordinates to find the value of b.

Using the point-slope form of a line, we have y - y1 = m(x - x1). Substituting the given values, we get y - (-1) = -5/2(x - 8). Simplifying, we have y + 1 = -5/2x + 20. Moving the 1 to the other side, we have y = -5/2x + 19. This is the equation of the line in slope-intercept form.

Answer:

  √2

Step-by-step explanation:

You want the distance between the lines y = -x +2 and y = -x +4.

The distance from point (x, y) to line ax +by +c = 0 is given by the formula ...

  [tex]d=\dfrac{|ax+by+c|}{\sqrt{a^2+b^2}}[/tex]

Rewriting the equation of the second line to general form, we have ...

  y = -x +4

  x +y -4 = 0 . . . . . . . a=1, b=1, c=-4

The equation of the first line is written in slope intercept form, so we can identify the y-intercept as (0, 2). Using this point in the formula for the distance to the second line, we have ...

  [tex]d=\dfrac{|1(0)+1(2)-4|}{\sqrt{1^2+1^2}}=\dfrac{|-2|}{\sqrt{2}}=\sqrt{2}[/tex]

The distance between the lines is √2 units.
