2.(05.03 MC) Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 4^-X and y = 2^-x+1 intersect are the solutions of the equation 4^-X = 2^-x+1

Part B: Make tables to find the solution to 4^-x = 2^-x+1. Take the integer values of x between-2 and 2.

Part C: How can you solve the equation 4^-x = 2^-x+1 graphically?

Even just one of these would be helpful thx

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?
