C A chemist has a container of 12% peroxide solution and a container of 20% peroxide solution. She needs to mix the two
solutions to create 100 mL of a 14% solution. If x represents the amount of 12% peroxide solution and y represents the
amount of 20% peroxide solution she needs, which matrix equation can determine the amount of each solution she needs
to make the 14% solution?

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
