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

If f(x)= (3+x)/(x-3) what is the f(a+2)
Akimi4 [234]

Answer:

                           f(a + 2) = (5 + a) / (a - 1)

Step-by-step explanation:

To answer items such as this, we directly substitute the a + 2 to the all the x's in the function such that,

                           f(a + 2) = (3 + a + 2) / (a + 2 - 3)

Simplifying the function generated above,

                           f(a + 2) = (5 + a) / (a - 1)
