Please explain how I do this. Please and thank you lines l and m are parallel. line l can be represented by the equation 3x+2y=7. If line m passes through (2,1), write an equation in point-slope form of line m.

Which is the completely factored from of xy^3-x^3y

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet

The volume of gas a balloon can hold varies directly as the cube of its radius. imagine a balloon with a radius of 3 inches can hold 81 cubic inches of gas. how many cubic inches of gas must be released to reduce the radius down to 2 inches?
