Hey, Can someone help me, this can help my math grade go up ^^ Jack baked 12 muffins. This was half the number of muffins he made yesterday.

Which equation can be used to find, x, the number of muffins Jack made yesterday?

A. x+1 over 2=12
B. x−1 over 2=12
C. x over 2=12
D. 2x = 12

The equation shown below represents function f. f(x)= -2x+5 the graph shown below represents function g. which of the following statements is true? a. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is less than the y-intercept of function g. b. over the interval [2, 4], the average rate of change of f is greater than the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. c. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. d. over the interval [2, 4], the average rate of change of f is less than the average rate of change of g. the y-intercept of function f is the same as the y-intercept of function g.
