You can rewrite the function \{(1,2),\ (-2, 0),\ (3,0),\ (4, 6)\} as table

\begin{array}{cc}x&y=f(x)\\1&2\\-2&0\\3&0\\4&6\end{array}

The domain of the function is the set of all possible values for the variable x. In your case, the domain of the function f(x) is the set \{-2,\ 1,\ 3,\ 4\}.

The range of the function f(x) is the set of all possible values of the variable y. In your case, the range of the function f(x) is the set \{0,\ 2,\ 6\}.

Answer: Domain - \{-2,\ 1,\ 3,\ 4\} (option A), Range - \{0,\ 2,\ 6\} (option D).

45/6 simplifyed into a mixed number
aniked [119]

Answer:

7 1/2

Step-by-step explanation:

How many times does 6 fully go into 45?

7 times.

7 times 6 is 42, so subtract that from 45 and you will get 3/6 left over after finding 7 as a whole number.

simplify 3/6: 1/2

IF l || m , find the values of x and y
egoroff_w [7]

Answer:

x = 8

y = 21

Step-by-step explanation:

(7x + 12)° and (12x - 28)° are alternate interior angles. Alternate interior angles are congruent. Therefore:

(7x + 12)° = (12x - 28)°

Solve for x

7x + 12 = 12x - 28

Collect like terms

7x - 12x = - 12 - 28

-5x = -40

Divide both sides by -5

-5x/-5 = -40/-5

x = 8

(12x - 28)° + (9y - 77)° = 180° (linear pair)

To find y, plug in the value for x = 8.

12(8) - 28 + 9y - 77 = 180

96 - 28 + 9y - 77 = 180

Combine like terms

- 9 + 9y = 180

Add 9 to both sides

-9 + 9y + 9 = 180 + 9

9y = 189

Divide both sides by 9

9y/9 = 189/9

y = 21

Show ALL your calculations.
Nesterboy [21]

Answer:

<DEB= 125 degrees

Step-by-step explanation:

To get this, you would need to know all 2 angles of the triangle.

To find the first angle, simply do 180-107 to get 73(because supplementary angles add up to 180 degrees).

Next, 180-52(given angle)-73 to get 55 because the 3 angles of a triangle add up to 180(triangle angle sum theory).

You would see that <DEB is part of another supplementary angle so, do 180-55 to get 125.

<DEB=125 degrees.
