Reason: Alternate Interior Angles Theorem
B.
Statement: DÈ is parallel to AC.
Reason: AB is a transversal cutting De and AC.
C.
Statement: 2124, and 23 25.
Reason: Alternate Interior Angles Theorem
D.
Statement: 2124, and 23 25.
Reason: 21 and 24, and 23 and 25 are pairs of supplementary angles.

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?
