Answer:

If f(1)=0 then 1 is a root and (x-1) is a factor of f(x). divide f(x) by (x-1). you now have a quadratic. Find its roots by methods you know.  

actually this factors by grouping:

f(x)=x³+3x²-x-3

= x²(x+3)-1(x+3)

=(x+3)(x²-1)

=(x+3)(x-1)(x+1) // difference of squares

By zero product property roots are

-3, -1, 1

Answer:

6 Liters

Step-by-step

4 Lemons = 3 Liters

8 Lemons = 6 Liters

So its basicly multiplying it by 2  ^O^

Answer:

X = 6

Step-by-step explanation:

number of lemons. Liters

4 ---> 3

8 ---> X

= 4:8 = 3: X

= 4 = 3

8 X

= 4X = 3×8

= X = 3 × 8

Answer:

Angle T = Angle Q

Step-by-step explanation:

Logical

Answer:

15.

explaination:

let x be the number which we have to times to the ratio.

(5+x) + (6+x) =33

5x + 6x =33

11x = 33

x=3

so we need to times 3 the ratio to get the actual number.

boys: 5 × 3 =15

girls:6 × 3 = 18

checking the answer: 15+ 18 = 33

Answer:

5/9

12

Step-by-step explanation:

La clase entera es 1.

1/3 estudian español.

1/9 estudian italiano.

1 - 1/3 - 1/9 estudian alemán.

1 - 1/3 - 1/9 = 9/9 - 3/9 - 1/9 = 5/9

5/9 de los estudiantes estudian alemán.

n = numero total de estudiantes en la clase.

5/9 n = 15

9/5 * 5/9 * n = 15 * 9/5

n = 27

Hay 27 estudiantes en la clase.

27 - 15 = 12

12 estudiantes no estudian alemán.

Answer:

Each pen costs $3.60 (Each calculator costs $14.20).

Step-by-step explanation:

Let c represent calculator

Let p represent pen

3c + 7p = 67.8

6c + 2p = 92.4

Step 1: Solve 3c + 7p = 67.8 for c:

3c + 7p = 67.8

3c + 7p + −7p = 67.8 + −7p (Add -7p to both sides)

3c = −7p + 67.8

3c/3 = −7p + 67.8/3 (Divide both sides by 3)

c = −7/3p + 22.6

Step 2: Substitute −7/3p + 22.6 for c in 6c + 2p = 92.4:

6c+2p=92.4

6(−7/3p + 22.6) + 2p = 92.4

−12p + 135.6 = 92.4 (Simplify both sides of the equation)

−12p + 135.6 + −135.6 = 92.4 + −135.6 (Add -135.6 to both sides)

−12p = −43.2

−12p/−12 = −43.2/−12 (Divide both sides by -12)

p = 3.6

Step 3: Substitute 3.6 for p in c = −7/3p + 22.6:

c = −7/3p + 22.6

c= −7/3(3.6) + 22.6

c = 14.2 (Simplify both sides of the equation)

Answer:

c = 14.2 and p = 3.6

Hope this helps and have a great day :)

Answer:

Daria bought 11 refills of lemonade last month

Step-by-step explanation:

The equation is:

y = 2x + 9

The cup costs 9 dollars and is 2 dollars per refill

She spent 31 dollars so:

31 = 2x +9

Now we can solve!

2x + 9 = 31

Subtract 9 from both sides!

2x = 22

Divide both sides by 2!

x = 11

We know x is the amount of refills so,

Daria bought 11 refills of lemonade last month!

Answer: 1/3=n

Step-by-step explanation:

-1/2(2n + 4) + 6 = –9 + 4(2n + 1)

Distribute:

-1n-2+6=-9+8n+4

Combine like terms:

-1n-2+6=-9+8n+4

-1n+4=-5+8n

Add 1n on both sides:

-1n+4=-5+8n

-1n+1n+4=-5+8n+1n

4=-5+9n

Add 5 on both sides:

4+5=-5+5+9n

9=9n

Divide 9 on both sides:

9/9=9n/9

1=n

Step-by-step explanation:

181-7=174. 174/181

Answer:

1.  Chicago, Detroit, Kansas City. Because they’re larger cities where pop culture thrives.

2. Hot Jazz. Hot Jazz is heavily dependant on improvisation. The key element of hot jazz was artists coming up with music on the spot and fast paced as well.

3. The roaring 20s had a huge impact on jazz. The roaring 20s was one of the first major revolutions in pop culture where people were turning away from traditional things and turning to new ideas, music, clothing, etc. This caused jazz to boom because it was a brand new style that was less constricted by society than music created prior to it.

4.  A faster paced, more aggressive style of jazz.

5. A style of jazz that included many rock music characteristics.

6. Jazz, although less popular, can be found in lots of pieces today. It is either more modernized in new music, or is still the same as it was.

7. I like hot jazz the best because of the musical improvisation. I find it shows true talent the best in jazz musicians.

*The last questions not mentioned in the original question:

What are some ways that modern technology is used in music today that is different than music from when jazz originated? How do you think emerging technology will affect music in the future? - Music isn’t as real anymore. Most of today’s music in pop culture is produced by a computer rather than played live. Technology will, although continue to revolutionize music in the future, take away the element of true talent of music being played live like older jazz musicians once did.

According to Stefon Harris, what counts as a “mistake” in jazz? - Not incorporating or choosing to neglect other bandmate’s ideas when creating music.

Answer:

The probability is [tex]0.3819[/tex]

Step-by-step explanation:

We know that Teresa is playing a game in which she is dealt 8 cards from a deck that includes 3 jokers and 52 common cards (a total of 55 cards).

Let's define the following random variable :

[tex]X[/tex] : '' Number of jokers in the hand of Teresa ''

We need to find [tex]P(X\geq 1)[/tex]

This probability is equivalent to :

[tex]P(X\geq 1)=1-P(X=0)[/tex]

[tex]P(X=0)[/tex] is the probability of having none jokers in the 8 card hand.

In order to find [tex]P(X=0)[/tex] we are going to count all the cases in which [tex]X=0[/tex] (given that we are in presence of an equally - likely sample space)

We calculate [tex]P(X=0)[/tex] as :

[tex]P(X=0)=\frac{\left(\begin{array}{c}52&8\end{array}\right)\left(\begin{array}{c}3&0\end{array}\right)}{\left(\begin{array}{c}55&8\end{array}\right)}[/tex]

We define the combinatorial number [tex]nCr=\left(\begin{array}{c}n&r\end{array}\right)=\frac{n!}{r!(n-r)!}[/tex]

In the denominator we have [tex]\left(\begin{array}{c}55&8\end{array}\right)[/tex] which represents all the ways in which we can extract 8 cards from the deck of 55 cards.

In the numerator we have the product of [tex]\left(\begin{array}{c}52&8\end{array}\right)[/tex]  (which represents all the ways in which we can choose 8 cards from the 52 common cards) and   [tex]\left(\begin{array}{c}3&0\end{array}\right)[/tex]  (which represents that from the total of 3 jokers we extract 0)

 If we perform the operation we find that :

[tex]P(X=0)=0.6181[/tex]

Finally,

[tex]P(X\geq 1)=1-P(X=0)=1-0.6181=0.3819[/tex]

The probability is [tex]0.3819[/tex]

Answer:

x = 0

Step-by-step explanation:

5(x - 3) + 4(x + 3) = 3(x - 1)

5x - 15 + 4x + 12 = 3x - 3

5x + 4x + 12 - 15 = 3x - 3

9x - 3 = 3x - 3

9x = 3x - 3 + 3

9x = 3x

9x - 3x = 3x - 3x

6x = 0

6x ÷ 6 = 0 ÷ 6

x = 0

Answer:

5( x− 3 ) + 4 ( x +3)

9x − 3 = 3(x− 1 ) Simplify  3 ( x − 1 ) .

9 x − 3 = 3 x − 3

Move all terms containing  x  to the left side of the equation.

6 x − 3 = −3

Move all terms not containing  x

to the right side of the equation.

6 x = 0

Divide each term by  6  and simplify.

x = 0
