Question 51987: I have the following problem; rewrite this equation as a funtion of x; the eqaution is -3x + 4 = 11. If I'm doing this right I get as far as y = -3x + 11 and then I get competely lost, could you please explain the next step to me. I know I'm forgetting an operation, but can't remember what. Thank You.

Question 52209: This is "solving equation and problems" "Transforming equations-multiplication and division".
1/2x=22
I read something about getting the reciprocal of 1/2 so i guess 2/1. i dunno. can some one help by explaining the WHOLE precess to me. I think these are fractions, bu it could be division. I feel so stupid. Thanks

Question 52332: For the equation , perform the following:(x) minus sqrt of (x) equals (0)
a) Solve for all values of x that satisfies the equation.
b) Graph the functions y=x and y= sqrt of (x) on the same graph (by plotting points if necessary). Show the points of intersection of these two graphs.

Question 52496: x=-2, -1, 0, 1, 2
y=.25, .5, 1, 2, 4
Given the table above, graph the function, identify the graph of the function (line, parabola, hyperbola, or exponential), explain your choice, and give the domain and range as shown in the graph, and also the domain and range of the entire function.

Question 52757: I have 2 problems that sort of come together. My first is f(x)=ln(-x)
When i input this into my ti83+ an error comes up saying nonreal ans.I have done f(x)=ln x (first part of problem i'm working)
my second problem is f(x)=sqrt(-x) ( i have done f(x)=sqrt x

Question 53118: My question has come from a worksheet, not the actual text book. I am having trouble because my notes say I need to put it into point slope form, but I don't see how.
Here is my question:
Find the equation of a line through (-7,2) and perpendicular to y=2x.

Question 53302: I'm a homeschooling mom trying to help my daughter, but this problem we just can't understand. We need to solve(find the system of equations) first by graphing and then by adding or subtracting.
The problem is:
6X-4y=28
4X+9y=-6
We first decided to make X the same so we ended up with
24X-16y=112
24x+54Y=-36
Then we isolated the 24x so we ended up with
24x=112=16y
24x=-36-54y
I think then we have to take 24 by division off from the x side,but I just can't seem to make any sense out of it.
Thanks for your help.

Question 53300: I think I was able to do all of this correctly except for the graph. Can someone check this for correctness and show me what the graph should look like... Thanks
Using the formula, , let r = 10%, P = 1, and n = 1 and give the coordinates (t, A) for the points where t = 0, 1, 2, 3, 4. Round the A value to the tenth's place.
) Show coordinates in this space
(0, 1)
(1, 1.1)
(2, 1.2)
(3, 1.33)
(4, 1.46)
Show work in this space
A = 1(1+.10/10)^(1)(0)
A= 1(1 +.1)^0
A = 1(1.1)^0
A = 1(1)
A = 1
A= 1(1 + .10/10)^(1)(1)
A = 1(1.1)^1
A = 1(1.1)
A = 1.1
A= 1(1 + .10/10)^(1)(2)
A = 1(1.1)^2
A = 1(1.21)
A = 1.21
A= 1(1 + .10/10)^(1)(3)
A = 1(1.1)^3
A = 1(1.331)
A = 1.33
A= 1(1 + .10/10)^(1)(4)
A = 1(1.1)^4
A = 1(1.
