help me please explain how to do it with answer to each one of the questions. please

The velocity of a reaction is 20mM/min when the substrate concentration is 3mM. Calculate the Vmax, given that the Km of the reaction is 1.5mM. Make sure to include units with your answer! The line for a Lineweaver-Burk plot was determined to be y=0.01x+0.003. 1. What are the Km and Vmax of the enzyme? Round to the nearest hundredth for each; don't include any units. The line for a Lineweaver-Burk plot was determined to be y=0.01x+0.003, 2. An inhibitor was added and the new line formula was determined to be y=0.01x+0.006. Calculate a and = ;a= The line for a Lineweaver-Burk plot was determined to be y=0.01x+0.003. 3. An inhibitor was added and the now line formula was determined to be y=0.01x+0.006. What type of inhibitor was added? [5]
