Hi everyone. I calculated and i understood why the result is 3/2. But the infinit is negativeso i couldnt understand why the answer is not negative (Why is not -3/2?). Could someone help me to underst
Under X the numbers are -2, -1, 0, 1, 2. Under Y the numbers are 0, -1, -2, -3, -4
And can you help with this? If a graph shows Y intercept is 4 and X intercept is -4 what would be the rule?

A rocket is fired vertically from the surface of the earth at a velocity of 5km per second. The acceleration of the rocket is given by a= -80000/x^2 kilometres per second, where x is the distance of t
Hi,
I know how to do this problem and get the answer in my book; but i was wondering why this method does not give the correct answer?
Here is the question:
∫[(5x^2)+(3x)-(2)] / [(x^3)+(2x^2)]dx
over the given time interval for:
a) v(t) = 3t-2 for 0 ≤ t ≤ 2
b) v(t) = |1-2t| for 0 ≤ t ≤ 2-Displacement is distance traveled in one direction (in case you didnt know)
You need to integrate from v
solve for the equation.
4x -(3x-1) =2
the answer is 1. but how did they do the equation?-4x - (3x-1) = 2
4x - 3x + 1 = 2
1x + 1 = 2
1x = 1
x= 1-4x - (3x-1)=2
4x - 3x + 1 = 2
x + 1 - 1 = 2 - 1
x = 1

How do you solve this..
m = nb + q (b)
I got the answer ---> m-q/ n = b..
Not sure if its right though-nb + q = m
nb = m - q
b = (m - q)/ n
You are correct ( the other answers are miles out, the

transpose the equation r= 2rn/ n+1 to make n the subject-A^27 10

These problems confuse me completely. Simplify ->
1/1-x + x/x-1
x/1-x^2 - x/1-x
6x-18/x^2-16 • x^2+5x+6/x^2-9
(• = multiplying)Anyone to help gets Best Answer :}Thanks.-1)
You can see that 1 - x
its a review from like a year ago that i have to do, how do you do this?
|15-23| i know you have to change something but what?!-|a| means the modulus, or positive value of a.
For example |-45| = 45,
Solve. (x-20)^2=12
Is it 2√3+20,-2√3+20?-Well, the answers work... (plug them back into the equation)
(2√3+20 - 20)^2 = (2√3)^2 = 12
(-2√3+20 - 20)^2 =(-2√3)^2 = 12
Or you can do it the long way
(x-2
