If f(x)=2x+1/x-4, what is the value of f^-1(3)? a. 22/7 b. 19/11 c. 8/3 d. 13 e. 11

Simply 8x squared + 5(7x squared- x) - 2x =

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6
