Math 50 points if the measure of the complement of an angle is squared, it will equal 90 less than three times the supplement of the angle. find the measure of the angle. write a quadratic equation and solve by factoring. (hints: foil, if ax+bx+c-0, then ask yourself "what multiplies to 'c', but adds to 'b'? ")

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
