Graph the equation y=-x^2+10x-21 on the accompanying set of axes. You must plot 5 points including the roots and the vertex.

Which value of m will create a system of parallel lines with no solution? y= mx - 6 8x - 4y = 12

Aline passes through the point (–7, 5) and has a slope of 1/2 which is another point that the line passes through?

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18}, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.
