Operation of subtraction on the two radical expressions

4x+5/x+5 - 5x+6/x+5 please help me, thanks-Use brackets to make things clearer. I think you mean: (4x + 5)/(x+5) - (5x + 6)/(x+5) step 1: factor out the common denominator: [(4x + 5) - (5x + 6) ]

Partial Fraction Decomposition help

(x^2 +2) /((x-1)(x+2)^2) I assume this has a repeated linear factor and I worked out an answer but I probably did it wrong anyway. I got A=0.3125B= -0.5C= 0.33-I dont know why youd use decimal values

Radical equation solving

√-5+3y+1=6 the square root extends to 3y whats the answer? thanks in advance-sqrt(-5 + 3y) + 1 = 6 sqrt(-5 + 3y) = 6 - 1 sqrt(-5 + 3y) = 5 -5 + 3y = 5^2 -5 + 3y = 25 3y = 25 + 5 3y = 30 y = 30/3 y =

Symbolic Logic - What is it

I was thinking about taking a symbolic Logic Class because I heard its basically like a math class, but I wanted to know what kinds of things you learn in the class :\ Anyone know..-You pretty much ta

Solving this equation: 2logbase3(x) = logbase3(81)

O K, we are working in base 3.I will assume the 3 is there, and not repeat it endlessly. 2 log x = log 81 log x^2 = log 3^4 . . . . . . . (because 3^4 = 81) Therefore x^2 = 3^4 √(x^2) = √(3^4) x

What in degrees is Inverse Sin (-1/2)

Because its sin and its negative I know its not on the top two quadrants. How can I tell if its either in quadrant three or quadrant 4? If its in quadrant 3 then its -90 degrees and if its quadrant 4

How many possible phone numbers can be assigned using this system

In Sharon Springs, Kansas, all of the phone numbers begin 852-4. The only differences in the phone numbers are the last 3 digits. How many possible phone numbers can be assigned using this system? Ma

Z is the standard normal distribution. Find the indicated probability..

P(0.5 ≤ Z ≤ 1.4)-P(0.5 ≤ Z ≤ 1.4) = 0.2278 learn to look it up from a z-table. a convenient one is http://davidmlane.com/hyperstat/z_table.…

Got two answers for this -6 and -1 Its -1 but why isn't it also -6?logbase2(x+2) + logbase2(x+5) = logbase2(4)

when x = -6 log(x + 2) = log(-4) and log (x + 5) = log(-1) Since log of negative numbers is not defined, -6 is not valid one. only -1 is valid-Because if x = -6, (x + 2) = -4, and (x + 5) = -1. Log

P(A|B) = .1, P(B) = .7, P(A|B') = .5. Find P(B|A).

how do you do this?-Given : P( A | B ) = 0.1, P( A | B ) = 0.5, P( B ) = 0.7 ........ (1) ______________________________ P( A | B ) = P( A ∩ B ) / P(B) = 0.1 ∴ P( A ∩ B ) = (0.1) P(B) = (0.1)( 0.7

How to solve this ? 2lnx-(lnx)^2 =0

plz help me :S-2lnx - (lnx)^2 = 0 First, factor out the common lnx: lnx(2 - lnx) = 0 Now, for the left side to be 0, either term on the left must be 0, so we have: lnx = 0 and 2 - lnx = 0 First,

Rational Function Graphing Question

how do you determine were a graph intersects in the horizontal, oblique, slant asymtote. an example how would you decide that for a problem like this g(x)= x^2/x^2+x-6-g(x) = x²/(x²+x-6) = x²/((x+

Why is this not a valid probability mass function

*Corrected post* p(x) = 1/6 ( 3 - x ) for x = 0,1,2 I thought this was valid since 3/6 + 2/6 + 1/6 = 6/6 = 1 but the answers say its wrong. Annoyingly the answers dont say why? The question also h

What is this equation telling me

T= 1/16Pi^2 X c^3h/GMk And why speed of light cubed??-Could you please tell us where the equation is from?You mentioned the speed of light cubed, so I might guess that c is the speed of light. But wh
