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.
I am having trouble posting a response-getting an error message. I can't quote the above post.
"F" is common to both sides. I'm not sure what to do if that is the correct path.
Did I do this one correctly?
Homework Statement
If a = f - 2 and b = 4f + 5, what is an expression for b in terms of a?
It's multiple choice:
4a
4a - 4
4a + 2
4a + 7
4a + 13
The Attempt at a Solution
a = f - 2 and b = 4f + 5
add 2 to each side ----> a = f and b = 4f + 7...
Did I do this problem correctly?
Homework Statement
The √ sign extends over x+3 only. Solve for x.
√(x+3) + 3 = 9
The Attempt at a Solution
subtract 3 from each side
√(x+3) = 6
√(33 + 3) = 6
√36 = 6
x = 33
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.
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...
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...

The obvious answer is (0,0).
There have to be more. I don't know how to go about finding this answer.

Side RS =...
Was it the correct calculation? I may have a correct calculation but if the formula was wrong or the values the answer is wrong.
I'm really confused as to what the answer is.
I rounded it. I didn't round up to 5.1. I rounded down to 5.
Is 5.097019514 the correct answer?
Have I done any other calcs correctly?
Please steer me towards a calc that works. I don't want to give up.
