The diagram below shows a pentagram (a five-pointed star) inscribed inside a regular pentagon. there are several golden ratios in this figure. for example:
and .
this means that if length a = 2, then length b = 3.236. in this case, what is length c?
a.2.618
b.1.618
c.0.618
d.5.236
e.4.236

(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)
