Marcus' school is selling tickets to a spring musical. On the first day of ticket sales the school sold 3 adult tickets and 9 child tickets for a total of $75. The school took in $67 on the second day by selling 8 adult tickets and 5 child tickets. What is the price each of one child ticket?

Which of these choices show a pair of equivalent expressions?

100 points, hi, i’m not sure how to get the equation from the graph and table.

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.
