Find the inverse of the function f(x)= 2x - 4 and show explain each step used to find the inverse.

Acomputer store bought a program at a cost of $10 and sold it for $13. find the percent markup

Varies inversely with x. if y=8.5 when x=-1 find x when y=-1

Four equations are shown below.equation 1: y=2*equation 2: y=2x-5equation 3: y=x2 + 6equation 4: tdentify one linear equation and one nonlinear equation from the list.why each equation you identified is linear or nonlinear.nd one nonlinear equation from the list. state a reasonlinear equation
