Answer:

x = 4

Step-by-step explanation:

An exterior angle of a triangle is equal to the sum of the remote interior angles.

18x +5 = (46) +(-1 +8x)

10x = 40 . . . . . . . . . . . . . subtract (5+8x) from both sides, simplify

x = 4 . . . . . . divide by 10

__

<em>Additional comment</em>

The exterior angle is (18)(4) +5 = 77°. The marked unknown interior angle is -1+(8)(4) = 31°. The sum of the two remote interior angles is 46°+31° = 77°. The unmarked interior angle is 180°-77° = 103°.

Given two points M & N on the coordinate plane, find the slope of MN , and state the slope of the line perpendicular to MN .

telo118 [61]

Answer:

Problem 1) $m = \dfrac{1}{4}$ $slope_{perpendicular} = -4$

Problem 2) $m = \dfrac{1}{3}$ $slope_{perpendicular} = -3$

Step-by-step explanation:

$slope = m = \dfrac{y_2 - y_1}{x_2 - x_1}$

$slope_{perpendicular} = \dfrac{-1}{m}$

Problem 1) M(9,6), N(1,4)

$slope = m = \dfrac{6 - 4}{9 - 1} = \dfrac{2}{8} = \dfrac{1}{4}$

$slope_{perpendicular} = \dfrac{-1}{\frac{1}{4}} = -4$

Problem 2) M(-2,2), N(4,-4)

$slope = m = \dfrac{4 - 2}{4 - (-2)} = \dfrac{2}{6} = \dfrac{1}{3}$

$slope_{perpendicular} = \dfrac{-1}{\frac{1}{3}} = -3$

Write the slope-intercept form of the line through the points (4,-5) and (2, -1).

Leokris [45]

Slope intercept form is y=mx+b
to solve for m (slope) you must first subtract y2-y1 and x2-x1 then divide your answers

-1 - -5 = 4 (y)
2 - 4 = -2 (x)
4/-2 = -2

so your slope is -2

next plug in your slope and the point you choose

-1 = -2(2) + b
or
-5 = -2(5) +b
