Find the midpoint of the line segment joining points A and B.<br> A(2, - 5); B(4,1)

Nookie1986 [14]

Answer:

(3, -2)

Step-by-step explanation:

Find the midpoint coordinates (x, y) of points A(2, - 5) and B(4, 1)

x-coordinate of the midpoint is (2+4)/2 = 6/2= 3

y-coordinate of the midpoint is (-5+1)/2 = -4/2= -2

The mid point coordinates are (3, -2)

Use function notation to write the equation of the line

blondinia [14]

$f(x)=mx+b\to y=mx+b$

We have two points:

$(-3,\ 0);\ (-4,\ 7)$

The point slope form of the line:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

Substitute

$m=\dfrac{7-0}{-4-(-3)}=\dfrac{7}{-1}=-7$

$y-0=-7(x-(-3))\\\\y=-7(x+3)\\\\y=-7x-21$

Answer:

$f(x)=-7x-21$

The interior angle of a regular polygon is 4 times as large as the exterior angle.

Mrac [35]

Answer:

exterior angle = 36°

Step-by-step explanation:

In any polygon

exterior angle + interior angle = 180°

let x be the exterior angle then interior angle is 4x , then

x + 4x = 180

5x = 180 ( divide both sides by 5 )

x = 36

thus exterior angle = 36°
