Astudent drove to the university from her home and noted that the odometer on her car increased by 13.0 km. the trip took 20.0 min. (a) what was her average speed in km/h? km/h (b) if the straight-line distance from her home to the university is 10.3 km in a direction 25.0° south of east, what was her average velocity in km/h? km/h (c) if she returned home by the same path 7 h 30 min after she left, what were her average speed and velocity in km/h for the entire trip? average speed km/h average velocity km/h

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
