Mathematics - 19 September 2007

If anyone could explain how the following is done, it would be greatly appreciated!

Suppose that the gcd(a,b)=1. Prove that for every integer c, the equation ax+by = c has a solution in integers x and y (by finding a solution to au+bv=1 and multiplying by c).

i just need the beginning...the rest i can probably manage.
express in the simplest radical form to the nearest hundredth:

x squared + 3 = 7x how do i fix it so it quals to 0 its really easy but i forgot lol.



2x squared + 1 = 4x
this one also. how/?

if its like y = 3x + 1
then the y-intercept would be 1.
because slope-intercept form is y = mx + b, and b is the y-intercept. so how would you find the x-intercept of that equation????

assume there is no denominator.

7^8 over
7^2


-5pq^7 over
10p^6q^3


x^3y^0x-7

(5r-2)-2 over
(2r^3)^2

(r^2t5)0
(t^-1)


I will give you 10 points, this is xtra credit by the way.

Can you help me find z AND explain it? thanks!

and for these:

0.49k=6.272

solve for k

-5.73q= 97.41

solve for q

(32/3)x = -51/2

solve for x

3p= 4 1/5


solve for p



THANKS SO MUCH! =]

ok, so im doing linear equations in math and we had a sub. today who didn't bother to explain anything and was pretty pissy so i decided not to ask questions. anyone know how to do these? ex. 3x=5y and 3/x + 4/y =2 has something to do with moving around the numbers/letters. please.

the alternative form of the derivative ---
the limit as x approaches c of ( f (x) - f (c) ) / x - c.

the problem is f (x) = 4 - (x-3)^2 and c=2.

Showing work is very much appreciated.

So, I just started my junior year of college and apparently can' do 3rd grade math.

Here's part of my brother's math homework. Could someone explain it to me so I can help him out?

Ben says that he multiplied twice to find the number of cups in three quarts. Describe the steps Ben took to find the answer.

Help please?

Use what you know about problem solving to explain why your answer is correct. Use words, numbers, and/or symbols in your explanation
