The system of equations n=m and n=4 is the point (0,0). which of the following statements is true? a.)no point on the line is n=m is also on the line n=m ,0) is a solution to n=m and to n=4m c.)the graph of the solution is parallel lines d.)every solution to n=m is also a solution to n=4m

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

yes yes yes yes yes yes yes yes yes
