Answer:
= -80
Step-by-step explanation:
-77+-3x
The sum of the interior angles of a polygon with
sides is
![180(n-2)](https://tex.z-dn.net/?f=180%28n-2%29)
Since a pentagon has 5 sides, the sum of its interior angles is
![180(5-2) = 180 \cdot 3 = 540](https://tex.z-dn.net/?f=%20180%285-2%29%20%3D%20180%20%5Ccdot%203%20%3D%20540%20)
Since it is a regular pentagon, all sides and angles are the same, so one single angle measures
degrees.
Answer:
n=2
Step-by-step explanation:
3n-7=3-2n
5n=10 (add 2n on both sides and also add 7 on both sides of the equal sign)
n=2
DUBS
The measure of any interior angle of a convex regular n-gon is :
180 º - ( 360 º / n )
For a 30-sided polygon,
interior angle = 180 º - ( 360 º / 30 )
..................... = 180 º - 12 º
..................... = 168 º
Answer:
The equation is not linear
Step-by-step explanation:
You are given the equation
![\dfrac{2}{x}+\dfrac{y}{4}=\dfrac{3}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7Bx%7D%2B%5Cdfrac%7By%7D%7B4%7D%3D%5Cdfrac%7B3%7D%7B2%7D)
Express y in terms of x:
![\dfrac{y}{4}=\dfrac{3}{2}-\dfrac{2}{x}\\ \\\dfrac{y}{4}=\dfrac{3x-4}{2x}\\ \\y=4\cdot \dfrac{3x-4}{2x}\\ \\y=\dfrac{6x-8}{x}](https://tex.z-dn.net/?f=%5Cdfrac%7By%7D%7B4%7D%3D%5Cdfrac%7B3%7D%7B2%7D-%5Cdfrac%7B2%7D%7Bx%7D%5C%5C%20%5C%5C%5Cdfrac%7By%7D%7B4%7D%3D%5Cdfrac%7B3x-4%7D%7B2x%7D%5C%5C%20%5C%5Cy%3D4%5Ccdot%20%5Cdfrac%7B3x-4%7D%7B2x%7D%5C%5C%20%5C%5Cy%3D%5Cdfrac%7B6x-8%7D%7Bx%7D)
The linear function must of form
![y=mx+b,](https://tex.z-dn.net/?f=y%3Dmx%2Bb%2C)
where m and b are real numbers.
Your function is not of this form, so this is not a linear function.
