Answer:

Step-by-step explanation:

The slope-point form of an equation of a line:

$y-y_1=m(x-x_1)$

<em>m</em><em> - slope</em>

<em>(x₁, y₁)</em><em> - point on a line</em>

<em />

We have the equation:

$y-4=-2(x-6)$

hence

$m=-2,\ x_1=6,\ y_1=4\to(6,\ 4)$

Check other points:

Substitute the coordinates of the points into the equation and check the equality:

A. (-6, -4)

-4 - 4 = -2(-6 - 6)

-8 = 24 FALSE

C. (-4, -6)

-6 - 4 = -2(-4 - 6)

-10 = 20 FALSE

D. (4, 6)

6 - 4 = -2(4 - 6)

2 = 4 FALSE

Answer:

85.36 far north from the center

10.36 far east from the center

Step-by-step explanation:

The extra direction taken in the north side is x

X/sin(360-315)=50/sin 90

Sin 90= 1

X/sin 45= 50

X= sin45 *50

X= 0.7071*50

X= 35.355 steps

X= 35.36

Then the west direction traveled

West =√(50² - 35.355²)

West = √(2500-1249.6225)

West= √1250.3775

West= 35.36 steps

But this was taken in an opposite west direction

From the center

He is 35.36 +50

= 85.36 far north from the center

And

25-35.36=-10.36

10.36 far east from the center

Jot a set of objects where you can find a fractional part of the group using the total numbers of objects and by using subgroups

We divide the total set into several sub-sets (subgroups) that contain the exact same number of members. This way we know the number of total members by adding the number of total subsets.
