Answer:

[tex]x^3-10x^2+31x-28[/tex]

Step-by-step explanation:

Since we are looking for a polynomial with RATIONAL coefficients, then we know that if [tex]3-\sqrt{2}[/tex]  is a root, then its conjugate  [tex]3+\sqrt{2}[/tex] must also be a root

Therefore, we build the polynomial using binomial factors with the given roots as shown below:

[tex](x-4)*(x-3+\sqrt{2} )*(x-3-\sqrt{2} )= (x-4)((x-3)^2-2)=\\=(x-4)*(x^2-6x+9-2) =(x-4)*(x^2-6x+7)=\\=x^3-10x^2+31x-28[/tex]

Answer:

18y + 2z

Step-by-step explanation:

So first things is first, arrange all terms with the same degree.

8y + 10y - 3z + 5z + 2 - 2

Next combine like terms for everything

8y + 10y = 18y cuz 8 + 10 is 18.

-3z + 5z = 2z cuz -3 + 5 = 2

2 - 2 = 0 cuz that's a rule in math.

So the final answer is 18y + 2z.

You don't have a whole number cuz it is 0. You can put it there if you want as well.

18y + 2z + 0

( 3 , 2 ) Equation Form: x = 3 , y = 2

Answer:

(x=3, y=2)

Step-by-step explanation:

2x-y=4------equation1

x+y=5-----equation2

Add equation 1 to equation2

3x=9

x=9/3

x=3

substitute x=3 into equation 2

x+y=5

3+y=5

y=5-3

y=2

Answer:

A bat

Step-by-step explanation:

Answer:

The bat flies faster by 7 feet

Step-by-step explanation:

first, you need to find some common ground. 84 and 4 can both be divided by two 84/2=42 so now we know that:

-The bat flies 42 feet in two seconds

-The dove flies 35 feet in two seconds

So we know that the bad flies faster because the number is greater, but by how much?

To find this just subtract 35 from 42 to get 7.

So to summarize

The bat flies faster by 7 feet

Answer:

x = -47, y = 39

Step-by-step explanation:

2x+3y=23 →equation 1

3x+4y=15 →equation 2

by elimination method,

(2x+3y=23) × 4

(3x+4y=15) × 3

8x + 12y = 92

(-)      (-)       (-)

9x + 12y = 45

---------------------

-1x + 0    = 47

-x = 47

x = -47

substitute x=-47 in equation 1

2(-47) + 3y = 23

-94 + 3y = 23

3y = 23 + 94

3y = 117

y = 117/3

y = 39

therefore, x = -47 and y = 39

Answer:

1. 768 square yards

2. 384 square yards

Step-by-step explanation:

1. 16 x 16 = 256

  256 x 3 = 768 square yards

2. 16 x 16 = 256

   256/2 = 128

   128 x 3 = 384 square yards

Answer:

501.5

Step-by-step explanation:

Fill it in.

Answer: 2.7x (27 + 4x) - 45y + 2 = 501.5

Step-by-step explanation:

Start with 2.7x (27 + 4x)

so 2.7(5) = 13.5

and then you change the number that multiplies with the others:

13.5 (27 + 4x)

Then multiply them:

364.5 + 54x

And then add them with the rest of your equation:

364.5 + 54x - 45y + 2

Now multiply the numbers that have the variables:

364.5 + 54x - 45y + 2

54(5) = 270  and -45(3) = -135

then add them to the equation again:

364.5 + 270 -135 + 2

And then add them or subtract them altogether (I added 364.5 and 270 first and I got: 634.5. And then I subtracted/added -135 + 2 second and I got: -133.

then do 634.5 - 133 and you should get 501.5.

Given:

Total number of marbles in the bag = 150

There are 21 blue marbles for every 4 white marbles.

To find:

The number of blue marbles in the bag.

Solution:

Since, there are 21 blue marbles for every 4 white marbles, therefore the ratio of blue marble to white marbles is 21:4.

Let the number of blue marbles be 21x and white marbles be 4x.

Total number of marbles in the bag = 150

[tex]21x+4x=150[/tex]

[tex]25x=150[/tex]

Divide both sides by 25.

[tex]x=\dfrac{150}{25}[/tex]

[tex]x=6[/tex]

Now,

[tex]\text{Blue marbles}=21x[/tex]

[tex]\text{Blue marbles}=21(6)[/tex]

[tex]\text{Blue marbles}=126[/tex]

Therefore, the number of blue marbles is 126.

Answer:

{(2, 9), (5, 9), (1, -6), (-5, 5), (2,9), (5,9), (1,−6), (−5,5)}

Step-by-step explanation:

recall that for a function to be valid, every input must give one and only 1 output. (i.e every x-ordinate must have only one unique corresponding y-ordinate)

I have highlighted in bold and underlined the entries for each of the other choices where an x-value gives more than one possible y-value, hence these are not functions. only the first option satisfies this condition:

{(2, 9), (5, 9), (1, -6), (-5, 5), (2,9), (5,9), (1,−6), (−5,5)} Every x-value has a unique y-value, so it is possible that this is a function.

{(6, 6), (6, 8), (-8, -7), (-3, -8), (6,6),(6,8),(−8,−7),(−3,−8)}  (not a function)

{(1, 8), (9, -3), (7, -4), (7, -6), (1,8),(9,−3),(7,−4),(7,−6)} (not a function)

{(-5, -1), (-3, -7), (-5, 3), (-7, -4), (−5,−1),(−3,−7),(−5,3),(−7,−4)} (not a function)

Answer:

Step-by-step explanation:

If you substitute 0 to x the equation will not be right.

2*0 = 0 + 5

0 ≠ 5

0 is not equal to right. So 0 is not a solution for the equation.

The solution is actually 5. X=5

Answer:

:3))

Step-by-step explanation:

2x = x + 5                         original equation

2(0) = 0 + 5                      plug in 0 ("solution") for x

0 = 0 + 5                          simplify 2(0)

0 = 5 (not true)                 simplify 0 + 5

Because the final answer to the equation wasn't true when using the input value of 0 for x, we know that 0 is not a solution to this equation.

Answer:

Step-by-step explanation:

Given the expression of the speed satisfying the equation |S-60|≤17.5

The inequality expression will return both a negative and positive value.

For the positive value of the function;

S-60 ≤17.5

S ≤17.5+60

S  ≤ 77.5

For the negative value of the function;

-(S-60) ≤17.5

-S+60 ≤17.5

-S  ≤17.5 -60

-S  ≤ -42.5

multiply through by -1

S≥42.5

Hence the minimum speed limit is S≥42.5 while the maximum is S  ≤ 77.5

Answer:

17.5 tour guides are needed . In my idea.

Answer:

18

Step-by-step explanation:

If you add all of the students then divide by 8 you get 17.5. However, you can't have .5 of a tour guide, so you round up to 18.

28+35+22+33+22=140

140/8=17.5

17.5 ≈ 18 tour guides
