What is the x-intercept of the line with this equation 1/3x+y= -15?<br><br> (_,0)
Sidana [21]

( - 45, 0)

to find the x-intercept let y = 0 in the equation

x = 0 → \frac{1}{3} x = - 15

multiply both sides by 3

x = 3 × - 15 = - 45

x-intercept = ( - 45, 0)

Tan inverse X + tan inverse Y + tan inverse z=pie prove that X+Y+Z=xyz<br>​
vfiekz [6]

Answer:

see explanation

Step-by-step explanation:

Given

tan^{-1}x + tan^{-1}y + tan^{-1} z = π

let

tan^{-1}x = A , tan^{-1}y = B , tan^{-1}z = C , so

x = tanA, y = tanB , z = tanC

Substituting values

A + B + C = π  ( subtract C from both sides )

A + B = π - C ( take tan of both sides )

tan(A + B) = tan(π - C) = - tanC ( expand left side using addition identity for tan )

\frac{tanA+tanB}{1-tanAtanB} = - tanC ( multiply both sides by 1 - tanAtanB )

tanA + tanB = - tanC( 1 - tanAtanB) ← distribute

tanA+ tanB = - tanC + tanAtanBtanC ( add tanC to both sides )

tanA + tanB + tanC = tanAtanBtanC , that is

x + y + z = xyz
