Order the polynomial -x^4 y^2 + 7x^3 y^3 - 3xy^5 + 2x^2 y^4 in descending powers of x.

How do the graphs of y = 1/x and y=5/x+6 compare?

The height of a flare fired from the deck of a ship in distress can be modeled by h(t)= -2(8t^2-52t-28), where h is the height of the flare above water and t is the time in seconds. a. find the time it takes the flare to hit the water.

[15 points]find the least common multiple of the expressions: 1. 3x^2, 6x - 18 2. 5x, 5x(x +2) 3. x^2 - 9, x + 3 4. x^2 - 3x - 10, x + 2 explain if possible
