have a nice day

Options:

The reasonable domain contains only positive real numbers.

The reasonable domain contains only positive whole numbers.

The reasonable domain contains only real numbers greater than 3.

The reasonable domain contains only rational numbers greater than 3.

Answer:

(b) The reasonable domain contains only positive whole numbers.

Step-by-step explanation:

Given

[tex]f(x) = 0.5x + 3[/tex]

Required

True statement about the limitation of the domain

Since the domain (x) represents people, then it must be a positive whole numbers

This eliminates options (a) and (c)

The range of the function is not given. So, we can assume that any number of people can be present.

This eliminates option (d).

Hence: (b) answers the question

Answer:

Miguel needs 1,369/9 square inch of carpeting

Step-by-step explanation:

Here, we want to know the size of carpeting needed to cover the floor

What we have to do here is to find the area of the bedroom floor

Mathematically, we have this as the product of the dimensions of the floor;

This will give;

12 1/3 inches * 9 1/4 inches

= 37/3 * 37/3 = 1,369/9 square inches

Answer:

i believe the answer is 10.5

Step-by-step explanation:

dime = 3.14 (1.8) =5.62 cm

Since the coin rolled about 10.5 cm in 4 rotations, it means that the circumference of the coin (x) multiplied by 5 is equal to the distance rolled.

4x=41.8

x =41.8/4 =10.5cm

good luck :)

i hope this helps

Answer: D- a reflection of ^RST across the line y=-x

Step-by-step explanation:

The solution is, O a reflection of RST across the line y=-x, is the reflection which will produce an image of RST with a vertex at (2, -3).

Reflection is a type of transformation that flips a shape in a mirror line (also called a line of reflection) so that each point is the same distance from the mirror line as its reflected point.

here, we have,

from the given figure,

we get,

Triangle RST has,

vertex R ( -1,3)

vertex S ( 3, -2)

vertex t (1, -4)

now we know that,

the rule of a reflection across the line y=-x,

(x, y) ⇒ (-x, -y)

so, we get, here,

vertex S ( 3, -2) ⇒ vertex at (2, -3)

so, there is  O a reflection of RST across the line y=-x.

Answer:

.2(x+1)(x+5)

Step-by-step explanation:

Well first lets start with the x intercepts which are -1 and negative 5 so the equation must be either -0.2(x+1)(x+5) or .2(x+1)(x+5)

Notice how the graph is going upwards this means the number in front of the equation -.2 or .2 must be positive making .2(x+1)(x+5) this is because if .2 was negative the graph would be going downwards

Answer:

The missing number of chicken nuggets is 5.

Step-by-step explanation:

To find the mean of this data set, we must add every number together, then divide the sum by how many numbers are present.

Like this,

1 + 3 + 0 + 6 = 10

10 / 4 = 2.5

There are 4 present numbers in this data set, and one is missing.

Since the only number divided by 5 that would give you a quotient of 3 is 15, the missing number is 5.

Because,

1 + 3 + 0 + 6 + 5 = 15

15 / 5 = 3

Therefore, 5 is the missing number of the data set.

The Volume of the rectangular prism is 210cm

Answer:

$4

Step-by-step explanation:

We need to set up an algebraic expression to solve this problem:

 Let n= cost of a notepad

Let p= cost of a pen

 First set up an expression for Cynthia's purchase:

 cost of notepads*number of notepads + cost of pens*number of pens = total cost

 n*2 + p*3 = 40.30

 Rewrite as:

2n + 3p = 40.30

 Next, set up an expression for Annie's purchase:

 Here we will be using the same variables

  n*3 + p*5 = 61

 Rewrite as:

 3n + 5p =61

 Now, set up a system of equations:

 2n + 3p = 40.30

3n + 5p =61

 A system of equations can be solved in several ways, here I will use the addition/elimination method

For this method one of the variables must be able to be eliminated

Step 1: Pick a variable to eliminate

Here I will eliminate n

Step 2: make the selected variables in the equations equal and opposite so that they cancel out when the equations are added together

(2n + 3p = 40.30)(-3)

(3n + 5p =61)(2)

-6n - 9p = -120.90

6n + 10p = 122

Step 3: add vertically

-6n - 9p = -120.90

6n + 10p = 122

         p  =  1.10

Step 4: Figure out the other variable by inputting the answer you just got back into the original equation

2n + 3(1.10) = 40.30

2n + 3.30 = 40.30

      -3.30      37

         2n = 37

        /2     /2

         n = 18.5

One notebook = $18.50

One pen= $1.10

 18.50+1.10= $19.60

 2nd step

We must first set up an algebraic expression

 total=15 pencils

total=9 pens

 The total amount is the price of one pencil*15

 To figure out one pencil:

10 pencils are $24

1 pencil is $2.40

 Total= $36

 9 pens = 36

Therefore 1 pen is $4

Answer:

x = [tex]\frac{7}{10}[/tex]

Step-by-step explanation:

Given

4x - [tex]\frac{4}{5}[/tex] = 2 ( multiply through by 5 to clear the fraction )

20x - 4 = 10 ( add 4 to both sides )

20x = 14 ( divide both sides by 20 )

x = [tex]\frac{14}{20}[/tex] = [tex]\frac{7}{10}[/tex]

x=7/10

Step-by-step explanation:

4x-4/5=2

multiply all through by 5

20x-4=10

collect like terms

20x=14

divide all through by 20

x=14/20

x=7/10

Answer:

b. 5z-10 = 5(z-2)    c. c-2c^2= c(1-2c)    d. r+r+r+r= r(1+1+1+1)= 4r   e. 2x-(1/2) = (1/2)(4x-1)

Explanation:

you just need to find a common factor that you can divide out  of each term. ex. with the 5z-10 both 5z and 10 are divisible by 5, so you can factor that out. to check the answers just multiply it. if you still don't get it, look up "factoring binomials"
