The sum of the measures of two complementary angles is 90 degrees. find the measure of the angle labeled x

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9

Graph the equationy=x^2 -[tex]y = x^{2} - 2[/tex]

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?
