Answer:

were is the chart? so I can answer

The equation that is shown by the graph is y = -x + 4

From the graph, we have the following observation:

The above means that the graph represents a linear equation

The points on the graph are

(0, 4) and (4, 0)

Calculate the slope using

m = (y2 - y1)/(x2 - x1)

This gives

m = (0 - 4)/(4 - 0)

Evaluate

m = -1

The linear equation is represented as

y = mx + c

So, we have

y = -x + c

Where c = y, when x = 0

So, we have:

c = 4

This means that

y = -x + 4

Hence, the equation that is shown by the graph is y = -x + 4

The new function resulting from the vertical translation of the function f(x) = x - 2. (Correct choice: C)

In this problem we find a linear equation, of which we are asked to traslated vertically, a task that can be done by rigid transformation known as vertical translation, which is defined by the following formula:

g(x) = f(x) + k       (1)

Where k is the change done on the function along the y axis. Please notice that there is a vertical translation in the + y direction if and only if k > 0, otherwise there is no change (k = 0) or a vertical translation in the - y direction if and only if k <  0.

If we know that f(x) = x - 2 and k = 4, then the resulting expression is:

g(x) = (x - 2) + 4

g(x) = x + (4 - 2)

g(x) = x + 2

Answer:

-7.71

Step-by-step explanation:

n = -54/7 = -7.71

Answer: 420 different codes.

Step-by-step explanation:

We have eight digits, {0, 0, 0, 0, 2, 2, 4, 4}

For the first digit of the code, we will have 8 options.

For the second we will have 7 options (because we already took one)

for the third one we will have 6 options, and so on.

for the fourth, we will have 5 options

for the fifth, there are 4 options.

for the sixth, there are 3 options.

for the seventh, there are 2 options.

And for the last, there is only one option.

The total number of combinations will be equal to the product between the numbers of options for each digit, then we will have:

C = 8*7*6*5*4*3*2*1

But there is something more, the zeros can permute and will give the same code (So we are counting the same code several times), we have 4 zeros, then the number of permutations of the zeros is:

4*3*2*1  = 24

the 4's also are repeated, two times in this case, the number of permutations is:

2*1 = 2

And the 2's also are repeated, also two times, the number of permutations is:

2*1 = 2

Because we do not want to count these repetitions, we need to divide the total number of combinations by these 3 numbers of permutations

This means that we need to divide the number of different combinations will be:

c = (8*7*6*5*4*3*2*1)/(24*2*2) = 420

So we can conclude that there are 420 different codes.

The number of eight digit codes she can make using the digits in her birthday is; 420 eight digit codes

The 8 digits code of her birth date are;

0, 4, 0, 2, 2, 0, 0, 4

Now, since there are 8 digits, then number of ways of arranging the 8 digits is 8!

Since there are some repetitions, then we have to consider the permutations for them too.

There are four 0's which is 4!

There are two 2's which is 2!

There are two 4's which is 2!

Thus, number of 8 digit codes she can make using the digits on her birthday is;

8!/(4! × 2! × 2!) = 420 eight digit codes

Answer:

The sequence of transformations are;

A translation by 1 unit left, followed by a reflection across the x-axis

Step-by-step explanation:

Here, we want to know the transformation sequence

Let us select one point

J(1,4)

to J’(0,-4)

To translate 1 unit right means that we are subtracting the value of 1 from the x-coordinate

That leaves us with (0,4)

To get the change in the y-coordinate value to negative, it means that we have reflected over the x-axis

x-axis reflection turns (x,y) to (x,-y)

So, the sequence of transformations that maps the two is;

A translation by 1 unit left followed by a reflection across the x-axis

Answer:

translation 1 unit left, then 180 degrees

Step-by-step explanation:

J (1,4)

K (6,4)

L (1,1)

Moving it 1 unit left,  x unit - 1

J (0,4)

K (5,4)

L (0,1)

Now, rotate it 180 degrees, (x,y) = (-x,-y)

J' (0,-4)

K' (-5,-4)

L' (0,-1).

Hence, the triangle JKL is transformed into triangle J'K'L' when a triangle JKL translates 1 unit to the left and then rotate 180 degrees about the origin.

Using the Pythagorean Theorem, the length of CD, to the nearest hundredth, is: 11.62.

The measure of the longest side of a right triangle when squared will be equal to the sum of the squares of the other smaller sides of the right triangle.

Given the following:

Side AB = 6

Side AC = 12

Based on the perpendicular bisector theorem, AD = 1/2(AB) = 1/2(6) = 3.

Using the Pythagorean theorem, we have:

Length of CD = √(AC² - AD²)

Length of CD = √(12² - 3²)

Length of CD = √(144 - 9)

Length of CD = 11.62

Thus, using the Pythagorean Theorem, the length of CD, to the nearest hundredth, is: 11.62.

Answer:

Step-by-step explanation:

-12 = 4(-6 + f)

-12 = (-6 * 4 + f * 4)

-12 = (-24 + 4f)

-12 = -24 + 4f

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Add '-4f' to each side of the equation.

-12 + -4f = -24 + 4f + -4f

Combine like terms: 4f + -4f = 0

-12 + -4f = -24 + 0

-12 + -4f = -24

Add '12' to each side of the equation.

-12 + 12 + -4f = -24 + 12

Combine like terms: -12 + 12 = 0

0 + -4f = -24 + 12

-4f = -24 + 12

Combine like terms: -24 + 12 = -12

-4f = -12

Divide each side by '-4'.

f = 3

Answer:

9. x = 12

10. x = 31

Step-by-step explanation:

9. Corresponding angles are equal, so technically you can move that (7x - 20) to be diagonal with the (4x + 16). Along with the corresponding angle, diagonal angles are equal to each other. Therefore you can set (7x - 20) equal to (4x + 16) to find x.

7x - 20 = 4x + 16

Solve

3x - 20 = 16

3x = 36

x = 12

Therefore x is equal to 12

Check:

4(12) + 16

= 64

7(12) - 20

= 64

10. All angles in a triangle have to add up to 180 degrees. Therefore, you can write your equation like this:

x + 2x + 25 + 2x = 180

Combine like terms

5x + 25 = 180

Solve

5x = 155

x = 31

Therefore, x = 31.

Check:

31 + 2(31) + 25 + 2(31) = 180

31 + 62 + 25 + 62 = 180

180 = 180

Answer:

This equation illustrates the associative property of the real number field, [tex](\mathbb{R},\, +,\, \cdot)[/tex].

Step-by-step explanation:

All four choices here are indeed properties of the field of real numbers, [tex](\mathbb{R},\, +,\, \cdot)[/tex]. However, the equation [tex](2 + x) + 3 = 2 + (x + 3)[/tex] makes use of only the associative property.

By identity property of fields, the real number field [tex](\mathbb{R},\, +,\, \cdot)[/tex] should contain an identity element [tex]e \in \mathbb{R}[/tex], such that for any element of that field [tex]a \in \mathbb{R}[/tex]:

[tex]a + e = a[/tex].

In particular, the identity element of the real number field [tex](\mathbb{R},\, +,\, \cdot)[/tex] is the real number [tex]0[/tex]. The identity property (of addition) would then read:

[tex]a + 0 = a[/tex] for any [tex]a \in \mathbb{R}[/tex].

By the distributive property of fields, for any three elements ([tex]a,\, b,\, c \in \mathbb{R}[/tex]) of the real number field [tex](\mathbb{R},\, +,\, \cdot)[/tex]:

[tex]a\cdot (b + c) = a \cdot b + a \cdot c[/tex].

[tex](a + b) \cdot c = a \cdot c + b \cdot c[/tex].

Note that this property features both addition and multiplication in the same equation. However, the equation in the question includes only addition. Therefore, this property would not apply here.

By the associative property of fields, for any three elements  ([tex]a,\, b,\, c \in \mathbb{R}[/tex]) of the real number field [tex](\mathbb{R},\, +,\, \cdot)[/tex]:

[tex]a + (b + c) = (a + b) + c[/tex].

[tex]a \cdot (b \cdot c) = (a \cdot b) \cdot c[/tex].

In particular, the equation [tex](2+ x) + 3 = 2 + (x + 3)[/tex] (where [tex]x \in \mathbb{R}[/tex]) illustrates the associative property of addition of the real number field.

Note that even though the location of the parentheses have changed, the elements are still in the same place (with [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] in the same order on both sides of the two equations.)

By the commutative property of fields, for any two elements  ([tex]a,\, b\in \mathbb{R}[/tex]) of the real number field [tex](\mathbb{R},\, +,\, \cdot)[/tex]:

[tex]a + b = b + a[/tex].

[tex]a \cdot b = b \cdot a[/tex].

The commutative property of fields allow the elements in the additions and in multiplications to be rearranged. (In contrast, the associative property allows for only the rearrangement of the parentheses.)

That doesn't apply to [tex](2+ x) + 3 = 2 + (x + 3)[/tex] because the numbers and symbols appear in the same order on both sides of the equation.

The unknown number will be 5 if we add two to twice a number, the result is twelve.

Let the unknown number be x.

Then the twice of the known number be 2x.

According to the given question.

If we add two to twice a unknown number, the result is twelve.

So, from the given scenario we can say that

2 + 2x = 12

Now we have a linear equation in one variable 2 + 2x = 12 and we have to solve it for x which gives us the unknown number.

Therefore,

2 + 2x = 12

⇒ 2x = 12 - 2   (subtracting 2 from both the sides)

⇒ 2x = 10

⇒ x = 10/2

⇒ x = 5

Hence, the unknown number will be 5 if we add two to twice a number, the result is twelve.
