Answer:
D) 15
Step-by-step explanation:
The sum of the interior angles of a polygon is given by
![(n - 2) \times 180](https://tex.z-dn.net/?f=%28n%20-%202%29%20%5Ctimes%20180)
We have that, the sum of the interior angles of a polygon is
26 right angles. We want to find n, the number of sides.
We substitute into the formula to get:
![(n - 2) \times 180 = 26 \times 90](https://tex.z-dn.net/?f=%28n%20-%202%29%20%5Ctimes%20180%20%3D%2026%20%5Ctimes%2090)
Divide through by 90
![2(n - 2) = 26](https://tex.z-dn.net/?f=2%28n%20-%202%29%20%3D%2026)
Divide through by 2
![n - 2 = 13](https://tex.z-dn.net/?f=n%20-%202%20%3D%2013)
![n = 13 + 2](https://tex.z-dn.net/?f=n%20%3D%2013%20%2B%202)
![n = 15](https://tex.z-dn.net/?f=n%20%3D%2015)
Given
f(x)= -3x - 5
g(x)= 4x - 2
Find
(f - g)(x)
substitute the f and g values in (f - g)
(f - g)(x)= -3x - 5 - (4x - 2)
change the signs in parentheses because there is a negative sign in front of the parentheses
(f - g)(x)= -3x - 5 - 4x + 2
combine like terms
(f - g)(x)= -7x - 3
ANSWER: (f - g)(x)= -7x - 3
Hope this helps! :)
x=4 y=5
if we put two pharases together
the answer is as follows pic :
x=4 y=5
A is (2, -1)
The X axis will not change since A is not going left or right of (2,2). You would count down 3 spaces for the y-axis and that would land you at -1 or you could solve by subtraction.
2-3= -1
The foci need to be equal distances from the center of the eclipse.
See the attached picture. I marked off all the points that were given as choice and from this you can see that that (-5,-4) and (-5,2) are both 3 units away from the center.
The answer is: (-5,-4) and (-5,2)
