Ineed with two algebra problems !
what is (f+g)(x)?
f(x) = 8x^2 + 16x + 6
g(x) = x^3 - 3x^2 - 9
(f+g)(x)= ?
(multiplication)
what is (f x g)(x)?
f(x) = x^3 - 4x +2
g(x) = x^2 + 2
(f x g)(x)?
for the !

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?
