Answer: The answer is D

Step-by-step explanation:

The value of x if D bisects A and B is 6

The given parameters are

D bisects A and B.

Length AD = 2x - 2

Length DB = x + 4

This means that

AD =DB

So, we have

2x - 2= x + 4

Evaluate the like terms

x = 6

Hence, the value of x if D bisects A and B is 6

Answer:

x=4

Step-by-step explanation:

Answer:

x=4

Step-by-step explanation:

2x-2=6

Okay, first we need to create the inverse of this equation.

The inverse of subtraction is addition.
2(x)-2=6


2x = 6+2

Now, we solve the right-hand side.

2x = 8

Then, divide both sides by the greatest common factor.

We get x by itself.

2x = 8

The coordinates of the midpoint of a segment with the given endpoints will be (1, 9.5).

Let AB be the line segment and C be the mid-point of line segment AB. Let the coordinate of point A (x₁, y₁), the coordinate of point B (x₂, y₂), and the coordinate of the mid-point (x, y).

Then the coordinate of the mid-point of the line segment is given as,

(x, y) = [(x₁ + x₂) / 2, (y₁ + y₂) / 2]

The endpoints are A(2, 14) and C(0, 5).

Then the coordinates of the midpoint of a segment with the given endpoints will be

(x, y) = [(2 + 0) / 2, (14 + 5) / 2]

(x, y) = (2/2, 19/2)

(x, y) = (1, 9.5)

The coordinates of the midpoint of a segment with the given endpoints will be (1, 9.5).

The price of a rake and a shovel is $22 and $25 respectively.

Let's assume the price of a rake is x and the cost of a shovel is y.

Now, Theresa purchased 10 rakes and 15 shovels for $595.

10x + 15y = $595                                                                      -------------------(1)

Taking 5 common out from each side of the equation,

5( 2x + 3y) = 5( 119)

2x + 3y = 119                                                                             ------------------(2)

Brett purchased 8 rakes and 20 shovels for $676.

8x + 20y = $676                                                                       ------------------(3)

Multiply equation (2) by 4 and subtract from equation (3),

8x + 20y - ( 8x + 12y ) = 676 - 476

8x + 20y - 8x - 12y = 200

8y = 200

y = $25

Therefore,

10x + 15y = 595

10x + 15(25) = 595

10x + 375 = 595

10x = 595 - 375

10x = 220

x = $22

Hence, the price of a rake and shovel is $22 and $25 respectively.

The formula for an arithmetic series  -5,-3.5,-2,-0.5,1, is An = A1 + (n-1)d

See the pattern

-5-(-3.5)= -1.5

-3.5-(-2)= -1.5

The formula for an arithmetic series  -5,-3.5,-2,-0.5,1, is  An = A1 + (n-1)d

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.

Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.

An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.

I) There are 8.76* 10³ hours in 1 year.

II) The exact number of hours in one year is 8.76582*10³ hours.

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

Given:

1 hour=3600 seconds

1 year = 31556952 seconds.

Now,

I)  Use scientific notation to estimate the number of hours in one year.

1 day = 24 hours

1 year = 365 days

So, number of hours in one year is given by,

=24*365

=8760

=8.76* 10³

So, there are 8.76* 10³ hours in 1 year.

II) 1 year = 31556952 seconds.

1 hour = 3600 seconds

In one year the number of hour is given by,

=31556952/3600

=8765.82

=8.76582*10³

So, the exact number of hours in one year is 8.76582*10³ hours.

III)

The exact numbers of hours using 365 days is 8760 which is written as  in scientific notation but using the given data we get  hours.

Answer: 52

Step-by-step explanation: it might not be it. GOD BLESS.

yes, actually it is possible. The mathematical expression f(x)=exp or ex denotes the exponential function.

The mathematical expression f(x)=exp or ex denotes the exponential function. The word, unless specifically stated differently, normally refers to the positive-valued function of a real variable, though it can be extended to the complex numbers or adapted to other mathematical objects like matrices or Lie algebras. When the input variable x appears as an exponent in the formula f(x) = axe, an exponential function is indicated. The exponential curve is influenced by both the exponential function and the value of x.

One of the key mathematical operations is the exponential function (though it would have to admit that the linear function ranks even higher in importance). We allow the exponent to be the independent variable to create an exponential function. The formula f(x)=2x is a straightforward example.

Hence, yes, actually it is possible.

Answer:

The last option:  x = 0

Step-by-step explanation:

The line of symmetry for a figure is a straight line that divides the figure into two congruent figures

The vertical line passing along the y axis is the line of symmetry and since it passes through all y values where x = 0, the equation is x = 0

The proof is completed and showed that < 2 ≅ < 3 as required.

Given data

<1 and <2 are linear pair

<1 + <3 = 180 degrees

required to proof <2 ≅ <3

linear pair implies mathematically that the sum of the two angles are 180 degrees, hence we have:

< 1 + < 2 = 180 degrees    equation 1

also given that,

< 1 + < 3 = 180 degrees    equation 1

equating equation 1 and equation 2 gives

The restriction will be f-¹(x) range: y ≥ 0

Domain of a function:

The domain of a function refers to the set of all possible inputs for the function. For example, we get that the domain of f(x) = x² is all real numbers, and the domain of g (x) = 1 / x is all real numbers except for x = 0( as it will make the function indefinite.) Some special functions can also be defined whose domain are limited.

Range of a function:

The range of a function refers to the complete set of all possible resulting values of the dependent variable, after we have substituted the domain.

So, the restriction will be f-¹(x) range: y ≥ 0 as x² will always be positive.

Therefore, the restriction will be f-¹(x) range: y ≥ 0.

Functions are ubiquitous in mathematics and are essential for formulating physical relationships in the sciences.

An example of this would be y=x².

If you put in anything for x, you get one output for y. We would say that y is a function of x since x is the input value.
