Answer:

3880 degrees

Step-by-step explanation:

18 gon = 18 sides

The sum of the measures of the interior angle of any polygon is the number of sides minus 2 multiplied by 180.

⇒ 18 - 2 x 180

⇒ 16 x 180

⇒ 2880

Solve this system of linear equations. Separate

tia_tia [17]

Answer:

(9,4)

Step-by-step explanation:

The given system is:

9x + 3y = 93

3x - 4y = 11

Multiply the bottom equation by 3 to get:

9x + 3y = 93

9x - 12y = 33

Subtract bottom equation from top one to get:

3y--12y=93-33

$15y = 60$

$y = \frac{60}{15}$

$y = 4$

We put y-value into the bottom equation:

$3x - 4 \times4= 11$

$3x - 16= 11$

$3x = 11 + 15$

$3x = 27$

$x = \frac{27}{3}$

$x = 9$

Help meee pleaseeeee

Answer:

1 x 10^21

Step-by-step explanation:

The initial number (2 x 10^4) is in scientific notation. Scientific notation must be written as: a X 10^n, where 0<a<10 and n is an integer. In this case, the number in scientific notation is being raised to the power of 5. When we raise a power by another power, we must multiply the power of all the terms by the additional power. In this case, we would get 2^5 x 10^20, this would be 10 x 10^20. Since the value of 'a' needs to be greater than 0 and less than 10, we need to move the decimal to the left and add another power to our 10: 1 x 10^21.

Question Each answer choice below represents a relation by a set of ordered pairs. In which of the answer choices is the relatio

son4ous [18]

The ordered pairs that represent functions are:

{(-3, 10), (-2, 13), (3, 13), (8, 12)}
{(-4,11), (5, 10), (-3, 3), (-1, 10)}

<h3>How to determine the ordered pairs?</h3>

For a set of ordered pairs to represent a function, the following must be true:

The x value must point to only one y value

In {(-3, 10), (-2, 13), (3, 13), (8, 12)} and {(-4,11), (5, 10), (-3, 3), (-1, 10)}, the x value point to only one y value

Hence, {(-3, 10), (-2, 13), (3, 13), (8, 12)} and {(-4,11), (5, 10), (-3, 3), (-1, 10)} are functions
