What do the following two equations represent?
-32 - y = 3
-2x – 2y = – 4

Which is f(5) for the function –2x2 + 2x - 3?

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?

Solve for the equation x. 2x + 22 = 4(x + 3)
