Whats the correct answer?

Two numbers have a sum of -19. one number is x. what expression represents the other number?

The difference of three and the reciprocal of a number is equal to the quotient of 20 and the number. find the number.

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.
