A motorboat leaves its dock and travels 2 kilometers north, 2 kilometers east, 2 kilometers west, and 6 kilometers south. How far and in which direction must the motorboat go to get back to the dock?
4 kilometers south
2 kilometers north
4 kilometers north
2 kilometers south

4 kilometers north

Step-by-step explanation:

2 kilometers north  up 2

2 kilometers east, right 2

2 kilometers west then left 2

We are now at the position of up 2 again

6 kilometers south down 6

up 2 down 6 leaves us at down 4

We are 4 km south

We will need to go 4 km north to get back to the dock

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
