An industrial system has two industries with the following input requirements. (a) To produce $1.00 worth of output, Industry A requires $0.30 of its own product and $0.40 of Industry B's product. (b) To produce $1.00 worth of output, Industry B requires $0.40 of its own product and $0.10 of Industry A's product. Find D, the input-output matrix for this system.

Which of the following is the inverse of y = 3∧x y = 1/3∧x y = ㏒3x y = (1/3) ∧x y = ㏒ 1/3∧x

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?

What is the slope of the line (-7,2) (4,6)
