What’s the length of the segments variable expressions ??

maxonik [38]

Answer:

$EF=9\ units$

Step-by-step explanation:

we know that

The <u><em>Trapezoid Mid-segment Theorem</em></u> states that: A line connecting the midpoints of the two legs of a trapezoid is parallel to the bases, and its length is equal to half the sum of lengths of the bases

so In this problem

$EF=\frac{1}{2}[AD+BC]$

substitute the given values

$x=\frac{1}{2}[(x-6)+(2x-3)]$

$x=\frac{1}{2}[3x-9]$

$2x=(3x-9)\\3x-2x=9\\x=9$

$AD=x-6=9-6=3\ units$

$EF=x=9\ units$

$BC=2x-3=2(9)-3=15\ units$

What is the slope of the line that passes through the points (-9, -3) and (1, -3)?

anastassius [24]

Answer:

The slope is 0.

Step-by-step explanation:

m= (y2-y1)/(x2-x1).

y2 is -3, y1 is -3.

x2 is 1 and x1 is -9.

m= -3 -(-3)/ 1- (-9)

m= 0/10

m=0
