A. y= 1/3x +5 doesn't make it even.

B. y=6 you get that with 2+4, It's related because 2+2=4 and 4+2=6 which makes it even.

C. wouldn't be neither because 2 & 3 aren't related because it's an odd number.

D. is not the answer because 2 and 4 are related to each other because 2+2 is 4.

Answer would probably be A.

Write the equation for a parabola with the focus at

katen-ka-za [31]

The answer is (y - 4)2 = -12(x - 2)
Since the graph is facing the left, the starting equation would be (y - k)2 = -4p(x - h).
(h, k) is the vertex of the graph. If you plot the focus and the directrix, you can see that the distance is 6. Divide 6 by 2, thus the vertex should be 3 squares away from the focus and 3 squares away from the directrix. The vertex is (2, 4). And since the distance from the focus to the vertex and the distance from the directrix to the vertex is 3, P = 3.
Insert the numbers in and you should get the last choice.

What is the sum of the interior angles

galben [10]

Answer:

The sum of the interior angle is 108°

Step-by-step explanation:

To find the sum of the interior angle, you need this equation:

$\frac{180(n-2)}{n}$ (The variable $n$ represents the number of sides does a shape have).

-Count the sides of the shape:

The following polygon shown, has 5 sides.

-After you have the number of sides of the polygon, use the number of sides for the equation and it will be written as:

$\frac{180(5-2)}{5}$

-Then, you solve:

$\frac{180(5-2)}{5}$

$\frac{180(3)}{5}$

$\frac{540}{5} = 108\textdegree$

So, the sum of the interior angle is $108\textdegree$ .
