Answer:

Domain: {x | x = -2, 2, 4}

Range: {y | y = -3, 0, 4}

Step-by-step explanation:

Domain of a function includes all possible values of x that are plotted on the x-axis on a grid.

The range includes all possible y-values.

The graph of the function given above has specific points that are marked clearly. Each specific values if x and y are clearly known.

Therefore, the domain of the function are -2, 2, and 4.

This can be written properly as {x | x = -2, 2, 4}

The domain value include -3, 0, and 4.

This can be written as {y | y = -3, 0, 4}

Answer:

  y = x² -8x +13

Step-by-step explanation:

Put the roots in the intercept form and multiply it out. For roots p and q, the quadratic is ...

  y = (x -p)·(x -q)

  y = (x -(4+√3)) · (x -(4 -√3))

  y = ((x -4) -√3) · ((x -4) +√3) = (x -4)² -(√3)² . . . . use the special product form

  y = x² -8x +16 -3 . . . . use the other special product form

  y = x² -8x +13

_____

Comment on the special product

There are a couple of quadratic special products that are useful to remember:

  the difference of squares: (a -b)(a +b) = a² -b²

  the square of a sum: (a + b)² = a² +2ab +b²

When working with quadratics that have complex or radical conjugate roots, the difference of squares form comes in handy sometimes.

Math can be a lot easier if you learn to recognize and use patterns.

Answer:

d = 6.4

Step-by-step explanation:

We can use the distance formula

d =sqrt( ( y2-y1)^2 + ( x2-x1) ^2)

d =sqrt( (3 - -2)^2 + (6-2) ^2)

d =sqrt( (5)^2 + (4) ^2)

d =sqrt( 25 + 16)

d = sqrt( 41)

d =6.403124237

Rounded to the nearest tenth

d = 6.4

Using the distance formula:

Distance = sqrt((x2-x1)^2 + (y2-y1)^2)

Distance = sqrt((6-2)^2 + ( 3- -2)^2)

Distance = sqrt(4^2 + 5^2)

Distance = sqrt(16+ 25)

Distance = sqrt(41)

Distance = 6.4

Answer:

27 degrees

Step-by-step explanation:

1= 63 degrees

Using alternating angles, acute angle made at T is 63 degrees.

Angles in a triangle add upto 180, thus, 90+ 63= 153

180-153 = 27

_________________________________

Step-by-step explanation:

_________________________________

STEP (1) :

The slope of the line y = - 9 is 0(zero) because it is a Horizontal line.

So the slope of the line which is parallel to y = -9 is zero .

_________________________________

STEP (2) :

We have this equation to find the slope-intercept form of the linear functions :

[tex]y - y(given \: point) = (slope) \times ( \: x -x(g \: p) \: ) \\ [/tex]

_________________________________

STEP (3) :

Now it is time to put the slope and the given point in the equation :

given point = ( 12 , -5 )

slope = 0

[tex]y - ( - 5) = 0 \times (x - 12) \\ \\ y + 5 = 0 \\ \\ y = - 5[/tex]

And we're done.

Thanks for watching buddy good luck.

Answer:

0.7(p−250)=p

Step-by-step explanation:

I just took the test

The equation that models the situation is 0.7p = p - $250

Let p represent the television's original price.

If store A advertises a 30% discount, the price of the television would be 70%(100 - 30%) of the original price. This can be represented with the expression 70% x p = 0.7p

If store B reduces the price by $250. This can be represented with the expression: p - $250.

If the prices are equal, the expressions can be equated together:

0.7p = p - $250

b. [tex]\frac{2}{5}[/tex]

c. [tex]\frac{14}{15}[/tex]

d. [tex]\frac{8}{15}[/tex]

Step-by-step explanation:

Given that there are two laptop machines and four desktop machines.

On a day, 2 computers to be set up.

To find:

a. probability that both selected setups are for laptop computers?

b. probability that both selected setups are desktop machines?

c. probability that at least one selected setup is for a desktop computer?

d. probability that at least one computer of each type is chosen for setup?

Solution:

Formula for probability of an event E can be observed as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

a. Favorable cases for Both the laptops to be selected = [tex]_2C_2[/tex] = 1

Total number of cases = 15

Required probability is [tex]\frac{1}{15}[/tex].

b. Favorable cases for both the desktop machines selected = [tex]_4C_2=6[/tex]

Total number of cases = 15

Required probability is [tex]\frac{6}{15} = \frac{2}{5}[/tex].

c. At least one desktop:

Two cases:

1. 1 desktop and 1 laptop:

Favorable cases = [tex]_2C_1\times _4C_1 = 8[/tex]

2. Both desktop:

Favorable cases = [tex]_4C_2=6[/tex]

Total number of favorable cases = 8 + 6 = 14

Required probability is [tex]\frac{14}{15}[/tex].

d. 1 desktop and 1 laptop:

Favorable cases = [tex]_2C_1\times _4C_1 = 8[/tex]

Total number of cases = 15

Required probability is [tex]\frac{8}{15}[/tex].

Answer:

3/8

Step-by-step explanation:

So 1/4 of a bag of potatoes holds 4 gallons of stew. So half that. 1/8 of a bag holds 2 gallons of stew. 1/4+ 1/8 = 3/8 of a bag. 2+ 4 = 6 gallons of stew. So he would need 3/8of a bag, or one bag (if you can't buy 3/8 of a bag) .

Step-by-step explanation:

Answer:

6x + 10 = 100

Step-by-step explanation:

Given

Six tables held the same amount of students

let the number of student held by 1 table = x

since there are 6 table holding same number of students

number of student held by 6 table = 6*x = 6x

given that

number of students held in a line = 10

therefore

total number of students = number of student held by 6 table + number of students held in a line

total number of students in cafeteria = 6x + 10

also given

One hundred students go to the cafeteria to eat lunch

6x + 10 = 100  

6x = 100 - 10 = 90

x = 90/6 = 15

thus,

the number of student held by 1 table = 15

thus, required equation can be used to find the number of students sitting at each table is 6x + 10 = 100
