What is the expression and value of "six less than nine times the sum of a number and eight" when n = 5? 9 (n 8) minus 6; when n = 5, the value is 111. 6 minus 9 (n 8); when n = 5, the value is 111. 9 (n) 8 minus 6; when n = 5, the value is 47. 6 minus 9 (n) 8; when n = 5, the value is 47.

The cost function will be of the form f(x) = x + 29.

A function have a set of dependent variable for the given or specified independent variable.

According to the given question Recycled​ CDs, Incorporated, offers a choice of 5 used CDs for ​29 dollars with each additional CD costing a dollar.

We have to write a function for purchasing 5 or more CDs where x represents the no. of CDs over 5.

Let f(x) represents the cost of CDs.

∴ f(x) = x + 29.

Here the constant 29 dollars represents the cost of 5 CDs and x represents no. of CD's over 5.Put x = 0 and the cost for 5 CDs will be 29 and for any more value of x we will get our desire result.

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
/2     /2
x = 4

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

< 1 + < 2 = < 1 + < 3

< 2 = < 3

Answer: The answer is D

Step-by-step explanation:

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.

Comparing these answers the first one has only 3 significant figures and the second answer has six significant figures.

The value of h(g(t))(-6) is 24.

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

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.

Given:

g(t) = t² + 4t

h(t) = 2t

h(g(t))

=h( t² + 4t)

=2( t² + 4t)

And, h(g(t)) (-6)

=2( (-6)² + 4(-6))

=2(36-24)

Explanation:

Vertical angles are always congruent.

Set the two expressions equal to one another and solve for x.

6x - 6 = 3(x+6)

6x - 6 = 3x + 18

6x - 3x = 18 + 6

3x = 24

x = 24/3

x = 8

Then use this x value to find each angle

Both angles are 42 degrees each to confirm the answer.

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.

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)

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

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.
