Find the values of x and y in parallelogram PQRS. PT = y, TR = 4x + 1, QT = 2y, TS = 3x + 12

Solve the system of equations. y= 2x y= x^2 - 15

Consider the reaction 2x2y2+z2⇌2x2y2z which has a rate law of rate= k[x2y2][z2] select a possible mechanism for the reaction.

Graph g(x)=2cosx . use 3.14 for π . use the sine tool to graph the function. graph the function by plotting two points. the first point must be on the midline and closest to the origin. the second point must be a maximum or minimum value on the graph closest to the first point.
