Anna and tamara have four suitcases.
anna’s suitcases’ weights are represented by x + 4 and 4x - 5.
tamara’s suitcases’ weights are represented by -3x + 2 and 2x + 4.
write an algebraic expression that represents
the total weight of all the suitcases.

Graph a sine function whose amplitude is 3, period is 4π , midline is y = 2, and y-intercept is (0, 2) . the graph is not a reflection of the parent function over the x-axis. use the sine tool to graph the function. the first point must be on the midline and the second point must be a maximum or minimum value on the graph closest to the first point.
