Explain a process for solving the system of linear equations by placing the steps in order (with what is done first at the top of the list).
(1) X - y = 2
(2) 3x + y = 10

Factorize: x^2+8x+10 i just solved it but i don't know if the process is correct

How many terms does the polynomial x^2 y^2 have

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?
