What do we get when we form the product of av, where a is an mxn matrix and v is a column n-vector?

Two parallel lines are crossed by a transversal. what is the value of x? x = 40 x = 70 x = 110 x = 130

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.

X+ y = 5 ; x - y =3 solve using linear combination
