Part B Construct the line that is perpendicular to the directrix and passes through the focus. This line will be the axis of symmetry of
the parabola.
What are the coordinates of the point of intersection, A, of the axis of symmetry and the directrix of the
parabola?

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?

The power generated by an electrical circuit (in watts) as a function of its current c (in amperes) is modeled by p(c)= -15c(c-8) what current will produce the maximum power?
