Use a paragraph proof to prove the corresponding angles postulate:

given: segment a b is parallel to segment c d.

prove: corresponding angles are congruent

transversal ef cuts through parallel lines segments ab and cd creating four sets of corresponding angles; angles 1, 2, 3, 4 are formed by ef and ab; angles 5, 6, 7, 8 are formed by the ef and cd.

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?
