Ok, i need help identifying and graphing linear equations and putting them in standard form. So can anyone give me a couple of answers and tell me how you got them???!!Please

the directions say to determine whether each equation is a linear equation,if so write the equation in standard form
1) 3x=5y

2) 6xy + 3x =4

3) 7y=2x + 5x

4)3/x +4/y =2

5) 7n - 8m =4 - 2m

Thank you to anyone who can help me!!

point (x_0,y_0), suppose x_0 = 0....blah blah

What is "_" ?
I have no idea how to read. Is x_0 = x(0)?
Or something else?

Please explain in detail about "_" notation
Thanks

Given that m divides n, how do I find a homomorphism where phi(Z_n) = Z_m ? Please explain...

Please if you have no idea what a homomorphism is, keep your stupid comments to yourself!!!

Reviewing some questions for test prep, and stuck on this one:

Maximize - z = 5x1 + 3x2 + 7x3
Subject to: 4x1 + 3x2 + 2x3 < 60
3x1 + 4x2 + x3 < 24
x1 > 0, x2 > 0, x3 > 0

Please help, I stuck at linear programming!

This problem is from the Prentice Hall Geometry book in p. 187.

Three red hats and three blue hats are packed in three boxes, with two hats to a box. There is a picture, which is that the 1st box has two red hats, the 2nd box has two blue hats and the 3rd box has one blue hat and one red hat. The boxes i just described are all labeled incorrectly. To determine what each box actually contains, you may select one hat from one box. Explain how this will allow you to determine the contents of each box. (Hint: List all possible solution; then use logic to solve.) FYI: This is for school

A tractor is pulling 2 cars through the mud. The magnitude of the resultant vector is 5000lbs along the x-axis. Find the tension in the tow lines if they make a 15 degree angle with the axis of the tractor. Thank-you in advance for the help i got a big test coming up and need to know this subject. it is my weakest one. thank-you

Comparing Accelerations
How does the acceleration of an object traveling eastward slowing down at a rate of 5 m/s2 compare to the acceleration of a second object traveling westward speeding up at a rate of 5 m/s2?

and


At the top of a hill, a rollercoaster is traveling with a velocity of 2.0 m/s downward, but accelerates to 15.0 m/s by the time it reaches the bottom of the hill. If it took 2.0 seconds to reach the bottom of the hill, what was its acceleration?

and

What is the final velocity of an object starting from rest which accelerates at 17.0 m/s2 northward for 3.0 seconds?

Curve C has the equation
y=(x-1)(x^2-4)

It cuts the x axis at the points (-2,0)(1,0)(2,0)

y=x+7 is an equation of the tangent to C at the point (-1,6)

The tangent to C at the point R is parallel to the tangent at the point (-1,6)

find the exact coordinates of R.


Impossible really.
