Please please answer this correctly I have to finish the sums today as soon as possible
After pulling out of a garage, a car travels 15 miles north, 40 miles east, and 15 miles south. How many miles is the car from the garage?
50 miles
40 miles
30 miles
55 miles

Step-by-step explanation:

Since the north and south are opposite directions, you can subtract the distances in order to get your total vertical displacement.

8 miles south - 5 miles north = 3 miles south

After this, you use the Pythagorean theorem in order to get the hypotenuse of the triangle formed by the legs for 3 miles and 6 miles. (I strongly recommend you draw a diagram in order to visualize what the problem is asking)

a^2 + b^2 =c^2

3^2 + 6^2 = c^2

9 + 36 = c^2

45 = c^2

c = √45, or 3 √5

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

actually what is a question i don't understand
