I need help with geometry and it's a times test.

Which function is odd check all that apply a. y=sin x b. y=csc x c. y=cot x d. y=sec x

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

Which ordered pair is a solution to the system of linear equations? 2x + 3y= 6 –3x + 5y = 10
