Find the midpoint M of the line segment joining the points S = (-8, 3) and T = (2, -1).

Alex

Step-by-step explanation:

use the midpoint formula

$( \frac{xs + xt}{2} \: \: \frac{ys + yt}{2} )$

substitute into the midpoint formula

$( \frac{ - 8 + 2}{2} \: \: \frac{3 + ( - 1)}{2} )$

solve the above

(

$(3 \: \: 1)$

so the x coordinate if your midpoint is 3

the y coordinate of your midpoint is 1

(3;1)

$5 {w}^{2} - 5w = 0\Leftrightarrow 5w(w - 1) = 0\Leftrightarrow w = 0 \: \vee \: w = 1 \\ - 10 {n}^{2} + 35n = 0\Leftrightarrow - 5n(2n - 7) = 0\Leftrightarrow n = 0 \: \vee \: n = \frac{7}{2} \\ 2 {x}^{2} + 15x = 0\Leftrightarrow x(2x + 15) = 0\Leftrightarrow x = 0 \: \vee \: x = \frac{15}{2} \\ 18 {c}^{2} + 6c = 6c(3c + 1) = 0\Leftrightarrow c = 0 \: \vee \: c = - \frac{1}{3} \\ - 32 {y}^{2} - 24y = 0\Leftrightarrow - 8y(4y + 3) = 0\Leftrightarrow y = 0 \:\vee \: y = - \frac{3}{4} \\ 3 {k}^{2} = 6k\Leftrightarrow k = 0 \: \vee \: k = 2 \\ 6 {h}^{2} = 3h\Leftrightarrow h = 0 \: \vee \: h = \frac{1}{2} \\ 4 {s}^{2} = 10s\Leftrightarrow s = 0 \: \vee \: s = \frac{5}{2} \\ - 42 {z}^{2} = 14z\Leftrightarrow z = 0 \:\vee \: z = - \frac{1}{3}$
