midpoint (-1,-9),(2,4)

פתרון

midpoint

(- 1, - 9), (2, 4)

(\frac{1}{2}, - \frac{5}{2})

צעדי פתרון

(\frac{x _{2} + x _{1}}{2}, \frac{y _{2} + y _{1}}{2})

(x_{1}, y_{1}), (x_{2}, y_{2})

נקודת האמצע בין

(x_{1}, y_{1}) = (- 1, - 9), (x_{2}, y_{2}) = (2, 4)

= (\frac{2 - 1}{2}, \frac{4 - 9}{2})

פשט

= (\frac{1}{2}, - \frac{5}{2})

\frac{8 x}{9 x - 1}

f (x) = tan (4 x)

f (x) = \frac{- 1}{x + 2}

f (x) = \frac{x + 3}{x ( x + 4 )}

f (x) = \frac{2 x + 5}{x - 3}
