If M is the midpoint of segment CD with CM = 3x + 1 and MD = 8x - 24, find CD.

ra1l [238]

X = 5 so that would mean if you plug it into both equations, segment CD would be 32 units long.

Solve open parentheses square root of 7 close parentheses to the 6 x power = 49x−6.

LUCKY_DIMON [66]

(sqrt7)^6x = 49x - 6

There is no easy way to solve this . Drawing a graph will give a good approximation.

Draw y = (sqrt7)66x

and y = 49x - 6 and see where they intersect

Ill draw it on desmos graphing tool and give you the link.

The endpoints of CD are C(3,−5) and D(7, 9).<br> The coordinates of the midpoint M of CD are?

Nutka1998 [239]

Answer:

M(5,2)

Step-by-step explanation:

We use the midpoint rule:

$( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} )$

We just have to find the arithmetic mean of the x and y-coordinates.

The endpoints of CD are given as C(3,−5) and D(7, 9).

We substitute these values to get:

$( \frac{7 + 3}{2}, \frac{9 + - 5}{2} )$

$( \frac{10}{2}, \frac{4}{2} )$

$(5, 2)$

Therefore the coordinates of the midpoint M of CD are (5,2)
