3. Insert 4 geometric means between - 3 and 9375. 4. If the first term of a geometric sequence is 8 and the common ratio is
3. What is the sum of the first 15 terms?

Just tell me how to set up the equation.

Find the value of x for which line a is parallel to line b

(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)
