Michael wrote the system of equations below, but he accidentally left out the coefficient of x in the first equation.
y=?x-2
3y=15x-6
If the system has infinitely many solutions, what must the missing value be?

The equation represents the function f, and the graph represents the function g. f(x)=3(5/2)^x determine the relationship between the growth factors of f and g. a. the growth factor of g is twice the growth factor of f. b. the growth factor of f is twice the growth factor of g. c. the growth factor of f is 2.5 times the growth factor of g. d. the growth factor of f is the same as the growth factor of g.
