Answer:

2x + 4y = 16.

Step-by-step explanation:

14x - 7y = 8

Convert to slope-intercept form:

-7y = -14x + 8

y = 2x - 8/7

The slope is 2 so the line perpendicular to it has a slope of -1/2, so we have:

y = 1/2x + c

This line passes through the point (-2, 5) so:

5 = -1/2* (-2) + c

5 = 1 + c

c = 5 - 1 = 4

So our equation is y = -1/2x + 4.

Convert to standard from

4y = -2x + 16

2x + 4y = 16.

JOURNEY CONSISTS OF TWO DISPLACEMENTSTHE FIRST IS 500m IN A NORTHERNLY DIRECTION AND THE SECOND IS 200m IN AN EASTRENLY DIRECTIO
damaskus [11]

9514 1404 393

Answer:

  see attached

Step-by-step explanation:

The scale of the drawing is 50 m per grid square.

The magnitude of the resultant can be found using the Pythagorean theorem:

  r = √(n² +e²)

  r = √(500² +200²) = 100√29 ≈ 538.52 . . . meters

__

The direction angle can be found using the arctangent function.

The angle east of north is ...

  arctan(200/500) ≈ 21.8014°

The resultant is 538.52 meters in the direction 21.8° east of north.
