Answer:

k = 4/19

Step-by-step explanation:

1/3 (- 12k + 30) = 6 + 15k

- 12/3k + 30/3 = 6 + 15k

- 12/3k - 15k = 6 - 30/3

- 12/3k - 15/1k = 6/1 - 30/3

- 12/3k - 45/3k = 18/3 - 30/3

- 57/3k = - 12/3

- k = - 12/3 / 57/3

- k = - 12/3 * 3/57

- k = - 12/57

k = 12/57

k = 4/19

Give the diagram below find the value of x
Aleks [24]

Answer:

Well this is Same side interior angles which would mean that its supplementary or 180.

So we can just,

4x-2+17x+14=180

Combine like terms

21x+12=180

Perform inverse

21x=168

Divide/isolate

x=8

So the value of (x) is 8

Step-by-step explanation:

Well here’s a little tip that might help

So in order to identify interior/exterior angles you have to find the location. The two lines are whats separates the inner and the outter.

The Outter are outside the two parralel lines, their not in between. There are 4 exterior angles.

The inner are the 4 angles between the two parralel lines. There are 4 interior angles.

So there are 5 different ways you would usually hear them.

Alternate interior angle

Alternate exterior angle

Same side exterior (or better known as Converese of the same side exterior)

Same side interior (better known as the converse of the same side interior)

Corresponding

Alternate is basically different sides, but they gotta be only one angle choice, exterior or interior, if correct it makes this slash or back slash if you connect the points.

Same side is basically same side and they have to be the right type (exterior/ interior)

Corresponing has to be the same side also but they have to have.One interior and one exterior.

Corresponing angles are congruent (equal)

Alternate exterior/interior are congruent (equal)

Same side exterior/interior Are supplemenaty (they equal 180)

Help please?!?!?!?!?!?!?
nadezda [96]

Answer:

Choice D is  correct answer.

Step-by-step explanation:

We have given two function.

f(x) =2ˣ+5x  and g(x)  = 3x-5

We have to find the addition of given two function.

(f+g)(x) =  ?

The formula to find the addition, we have

(f+g)(x) = f(x) + g(x)

Putting given values in above formula, we have

(f+g)(x) =   (2ˣ+5x)+(3x-5)

(f+g)(x) =   2ˣ+5x+3x-5

Adding like terms, we have

(f+g)(x) =   2ˣ+8x-5 which is the answer.

PLEASE HELP ME IlL MARK U BRAINLEST
pogonyaev

Using the concept of odd and even functions, it is found that the functions are classified as follows:

1. Even.

2. Odd.

3. Neither.

4. Odd.

<h3>What are odd and even function?</h3>

  • If f(x) = f(-x), the function is even.
  • If f(x) = -f(-x), the function is odd.
  • If none of the statements above are true, the function is neither.

For the square function, we have that:

  • f(x) = x².
  • f(-x) = (-x)² = x² = f(x).

Hence it is even. The square root function is defined only for non-negative values, hence it is neither odd nor even.

For the cube function, we have that:

  • f(x) = x³.
  • f(-x) = (-x)³ = -x³ = -f(x).

Hence it is odd, as is the cube root, as the cube root function is defined for all real values.

How do we derive the of laws of radicals?​
Yuki888 [10]
The laws for radicals are derived directly from the laws for exponents by using the definition a m n = a m n . The laws are designed to make simplification much easier. It is important to reduce a radical to its simplest form.
