What is 7hours and a quarter in decimal hours

Explain how you do each step what term makes it inconsistent y=2x - 4 ?

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)
