    Solve For B In Terms Of A

    b = 4(f - 2) + 5 b = 4f - 8 + 5 b = 4f - 13 Thank you

    Solve For B In Terms Of A

    I need to divide by f on both sides. a = -2 and b = 9 Would that make f = 0? And then b = 5? Oy I'm confused. I'll be out for the night at a family dinner in a bit. Please don't be upset if I don't get back to to the problem until tomorrow. I do appreciate the help.

    On the Graph, For How Many Values of x Does y=x?

    I sort of understand that. But I still don't understand what the answer is. How many are there? It seems that the number is infinite.

    On the Graph, For How Many Values of x Does y=x?

    Yes, at (0,0) I don't understand what you mean by the line y=x. I don't know where to draw it, or how/why it's just one line. I am sorry to confuse you. Things get lost in translation in this format. I'm not getting the concept but I am trying hard.

    On the Graph, For How Many Values of x Does y=x?

    No worries. I probably didn't phrase it as best as I could have phrased it. I appreciate the help. If I did it correctly, There are 2 points that touch the "S" on each line. I drew lines at (1,1), (2,2), etc and at (0,0). At 0, there are 3. I don't know what the actual number is though. I'm...

    On the Graph, For How Many Values of x Does y=x?

    An "S" shape is plotted. The points above the graph are symmetrical to the points on the bottom. The only point that is labeled is (1,1). The very center of the "S" is at (0,0). At (1,1), (2,2) etc, y=x The possibilities are infinite. If I am on the right track, what would the answer...
