Answer:

C. $f(a + 2) = \dfrac{5 + a}{a - 1}$

Step-by-step explanation:

Replace x with a + 2 and simplify the expression.

$f(x) = \dfrac{3 + x}{x - 3}$

Let x = a + 2

$f(a + 2) = \dfrac{3 + a + 2}{a + 2 - 3}$

$f(a + 2) = \dfrac{5 + a}{a - 1}$

Find the midpoint of the line segment joining the points (-2,-2) and (-4,9).

11Alexandr11 [23.1K]

Answer:

The answer is

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

$M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-2,-2) and (-4,9).

The midpoint is

$M = ( \frac{ - 2 - 4}{2} \: , \: \frac{ - 2 + 9}{2} ) \\ = ( - \frac{6}{2} \: , \: \frac{7}{2} )$

We have the final answer as

$( - 3 \: , \: \frac{7}{2} )$

Hope this helps you
