180 degree rotation means reflection about origin.
You can just change the sign of coordinates to get the new coordinates.

Answer is B.

Hope it helps!

In 180 degree rotation, magnitude remains same, and sign of the coordinate changes. So, the coordinates of Pre-image would be: Z (-9, -2)

In short, Your Answer would be: Option B

Hope this helps!

Two cyclists start at the same point and travel in opposite directions. One cyclist travels 4 km per hour faster than the other.
yaroslaw [1]

Answer:

the rate of the first cyclist: 28km/h

the rate of the 2nd cyclist 28+4= 32km/h

Step-by-step explanation:

x= the rate of the first cyclist

x+4= the rate of the 2nd cyclist

after 4 hours: + the first cyclist travels 4x  (km)

                       + the 2nd cyclist travels 4(x+4)  (km)

because the two cyclists are 240 km apart after 4 hours

=> 4x + 4(x+4) = 240 => x= 28
