Tyler is simplifying the expression 6-2x+5+4x. Here is his work:

What is the value of x in the equation 6(x + 1) – 5x = 8 + 2(x – 1)?

Which graph represents the equation y =4x

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?
