that can be used to find the approximate rate of change.

dy/ dx = (y1 - yo)/ h
or dy/dx = (yn+1 - yn-1) / 2h

Is there one that is better than the other?
Why is one preferable over the other? and which one is better to use?

Ray SU bisects angle RST. The measure of angle RSU=3x-1, the measure of angle UST=2x+13 and the measure of angle RST=6x-2. Find x.

heres the picture:

choices
12
14
41
82

and then there's a second question that goes along with the same diagram

Use the information from the previous question to find the measure of angle RSU.

12
14
41
82

thank you sooooooo much to anyone that can help.

of proofs; in Geometry I, mean. I hated those things; it's not that they were difficult; I was just unable to see what I would do with those things in the real world.

If you plot Y=X on a graph, how is it that you get the axis of symmetry?

Preferably through contradiction. So far, I have:

Assume the square root of some prime p is rational

Therefore, square root of p can be represented by the division of two non-canceling integers, a and b.

If we square both sides, we get p is equal to a squared over b squared.

....

Where do I go from here?

any number whose square is itself that number
example
x^2=x
it can be any integer,fraction ,imaginary accept 0 and 1

How do you solve this alggebra problem? It has me confused.

5-2(x+3)=x-3(x+1)

Say Person1 (P1) and Person 2 (P2) go on a road trip together. P1 says he will pay for the lodgings if P2 will pay for meals, admissions to things, etc. P2 agrees, but when the accounts total out, they find that P2 has payed $5 more than P1. P1 then says when they stop for gas for the tip home they can use thet to even thing up. The last tank of gas costs $40, so P2 tenders $15 to P1 ($40 divided by 2 is $20, minus 5 is $15). P1 says that is incorrect - P2 owes $17.50 for the gas ($40 minus the disputed $5 is $35 divided by 2 is $17.50). Who is correct?
