90° clockwise will go from (x, y) to (y, -x)

180° counterclockwise and clockwise will go from (x, y) to (-x,-y)

270° clockwise will go from (x, y) to (-y, x)

1. (5 ,2) 90° will become (2, -5)

2. (5, 2) 180° will become (-5, -2)

3. (5, 2) 270° will become (-2, 5)

4. (-5, 2) 90° will become (2, 5)

5. (-5, 2) 180° will be come (5, -2)

6. (-5, 2) 270° will be come (-2, -5)

7. (-2, 5) 90° will become (-5, -2)

8. (5, -2) 180° will become (-5, 2)

Hope this helps! Mark as brainliest please! :)))

By driving 8 mph faster than Bob, John can make a 230 mile trip in one half hour less. How fast does Bob drive on the trip? Roun

____ [38]

Answer: The speed of Bob is 56.8 km/hr.

Step-by-step explanation:

Let the speed of Bob be 'x'.

Let the speed of John be 'x-8'.

Distance covered = 230 miles

time = $1\dfrac{1}{2}=\dfrac{3}{2}\ hr$

According to question, we get that

$\dfrac{230}{x}-\dfrac{230}{x+8}=\dfrac{3}{2}\\\\230\dfrac{x+8-x}{x(x+8)}=\dfrac{3}{2}\\\\\dfrac{230\times 8}{x^2+8x}=\dfrac{3}{2}\\\\\dfrac{1840}{x^2+8x}=\dfrac{3}{2}\\\\1840\times 2=3x^2+24x\\\\3680=3x^2+24x\\\\3x^2+24x-3680=0\\\\x\approx 56.8\ km/hr$

Hence, the speed of Bob is 56.8 km/hr.
