Abe and ben each have a certain number of dollars. if abe gives ben $5 then abe and ben will have the same number of dollars. if ben gives abe $5 then abe will have twice as many dollars as ben. let a=abe's original dollars b= bens original dollars. express the problem as a linear system in a and b. solve the system for a and b by addition or substitution. tell who had what and use dollar sign $.

If given an equation of a line such as -1/2x+6 how would you create an equation of a line parallel and perpendicula to this line that goes through another point such as (4,10)

For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)

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?
