Noah and Lin are each trying to solve the equation ** - 62 -- 10 = 0. They know that the solutions to x = -1 are i and -i, but they are not sure how to use this information to solve for æ in their equation.
Here is Noah's work:
x? - 6x + 10 =0
x² - 6x = -10
x2 - 6x + 9 = -10 + 9
(x-3)
= -1
Show how Noah can finish his work using complex numbers.

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?
