What is the sum of 9.8 and 12.05 please i need help

Answer:

D

Step-by-step explanation:

x + 5 > 11

is the same as

x > 6

and because it is ">" and not ">=", the solution point is not included.

therefore the right graph is D and not C. an empty little circle means "excluded", while a filled, black circle means "included".

Answer:

[tex]2^{1} + 3^{1}[/tex], [tex]2^{3} - 2^{1}[/tex], [tex]3^{2}[/tex]

Step-by-step explanation:

[tex]3^{2}[/tex] = 9

[tex]2^{3} - 2^{1}[/tex] = 6

[tex]2^{1} + 3^{1}[/tex] = 5

Step-by-step explanation:

[tex]2 {}^{3} - 2 {}^{1} = 2 {}^{3} - 2 = 8 - 2 = 6[/tex]

[tex]2 + 3 = 5[/tex]

[tex] {3}^{2} = 9[/tex]

Answer:

y - 4 = 1/3 (x - 3)

Step-by-step explanation:

Answer:

y = 14/3 and 2

x = -13/3 and 1

(-13/3, 14/3) and (1, 2)

Step-by-step explanation:

[tex]x + 2y = 5 - - - (a) \\ {x}^{2} - {y}^{2} = - 3 - - - (b)[/tex]

for equation (a)

make x the subject of the formular:

[tex]x = 5 - 2y - - - (c)[/tex]

for equation (b)

[tex] {x}^{2} - {y}^{2} = - 3[/tex]

substitute for x as 5 - 2y in equation (b):

[tex] {(5 - 2y)}^{2} - {y}^{2} = - 3 \\ (25 - 20y + 4 {y}^{2} ) - {y}^{2} = - 3 \\ 25 - 20y + 3 {y}^{2} = - 3 \\ {3y}^{2} - 20y + 28 = 0 \\ (3y - 14)(y - 2) = 0[/tex]

therefore,

[tex]y = \frac{14}{3} \: \: and \: \: 2[/tex]

substitute for all values of y in equation (c):

for y = 14/3:

[tex]x = 5 - 2( \frac{14}{3} ) \\ \\ x = 5 - \frac{28}{3} \\ \\ x = - \frac{13}{3} [/tex]

for y = 2:

[tex]x = 5 - 2(2) \\ x = 5 - 4 \\ x = 1[/tex]

Answer:

(1, 2)

(-13/3, 14/3).

Step-by-step explanation:

x + 2y = 5

x² - y² = -3​

From the first equation x = 5 - 2y

Substitute for y in the second equation:

(5 - 2y)^2 - y^2 = -3

25 + 4y^2 - 20y - y^2 = -3

3y^2 - 20y + 28 = 0

Factoring:-

(3y - 14(y  -  2)   = 0

y = 2, 14/3.

So when y = 2, x = 5 - 2(2) = 1.

When y = 14/3, x = 5 - 2(14/3) = -13/3.

Checking the results in the second equation:

(1, 2):-

1^2 - 2^2 = -3    Correct.

(-13/3, 14/3):-

(-13/3)^2 - (14/3)^2 = -3   Correct.

The component form of the vector that translates will be 11i - 17j.

A spatial transformation is each mapping of feature space to itself and it maintains some spatial correlation between figures.

The translation does not change the shape and size of the geometry. But changes the location.

The point A(-4, 8) is translated to the point A'(7, -9). Then the rule of the transformation is given as,

(7, - 9) = (- 4 + x, 8 + y)

Compare the abscissa, then we have

7 = - 4 + x

x = 7 + 4

x = 11

Compare the ordinate, then we have

y + 8 = - 9

y = - 8 - 9
y = - 17

The component form of the vector that translates will be 11i - 17j.

More about the transformation of a point link is given below.

Answer:

720

Step-by-step explanation:

He has 8 books. He knows the placement of 2... so

8 - 2 = 6

To find the total... 6!

6*5*4*3*2*1 = 720

The required number of the ways the book is arranged on the shelf is 720 ways.

Given that,
Kareem is putting 8 books in a row on his bookshelf. He will put one of the books, Pride, and Prejudice, in the first spot. He will put another of the books, Little Women, in the last spot. In how many ways can he put the books on the shelf is to be determined.

In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.

here,
There are 8 books to be arranged, 1st and last place is fixed,
now remaining books = 8 - 2 = 6
now, a number of combinations can be formed with the number 6,
= 6!
= 6×5×4×3×2×1
= 720

Thus, the required number of the ways the book is arranged on the shelf is 720 ways.

Answer: Yes, the set of real numbers is closed under addition.

Explanation:

Let x and y be two real numbers. Their sum x+y is some other real number. This is what it means when we say the set of real numbers is closed under addition. Taking any two numbers and adding them will get us some other real number.

There is no way to have x+y be nonreal while x,y are both real.

Hi! I'm happy to help!

First, we need to get our two equations, so we need to look at what facts we have throughout the equation. It tells us that x is 3 times as much as y. We can use this to write our first equation:

3y=x

All of the interior angles inside of a triangle add up to 180°, and because we already have 3 angles, we can use this information to make our second equation:

x+y+45=180

Now, we have to use these equations together to get our answer.

Since we can replace 3y for x (first equation) we can replace it in our second equation:

3y+y+45=180

We edit both sides of the equation in the same way to get the same outcome, but to simplify. Since we are solving for y, let's isolate it by subtracting 45 from both sides:

3y+y+45=180

       -45  -45

3y+y=135

Let's combine the 3y and y to make things simpler:

4y=135

From here, we divide both sides by 4, to isolate y:

y=33.75

Now that we have our y value, we can use our first equation to solve for x:

3y=x

3(33.75)=x

101.25=x

We used our equations to get both our x and y values: 33.75, and 101.25.
