4. The school carnival is divided into sections. The dunk tanks are in LaTeX: \frac{1}{10} 1 10 of the carnival. Games are in LaTeX: \frac{4}{10} 4 10 of the carnival. Student exhibits are in LaTeX: \frac{5}{10} 5 10 of the carnival. Part A: What fraction of the carnival is dunk tanks and games?

(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)
