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

maxonik [38]

Answer:

$EF=9\ units$

Step-by-step explanation:

we know that

The Trapezoid Mid-segment Theorem 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

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

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

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

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

$EF=x=9\ units$

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

Find the x-intercept(s) Round to nearest hundredth if needed y=-2x^2-8x-4

kherson [118]

y=-2x^2-8x-4

-2x^2-8x=4

divide by negative 2

x^2+4x=-2

complete the square

(x+2)^2=-2+4

(x+2)^2=2

x+2=± $\sqrt{2}$

x=-2± $\sqrt{2}$

nearest hundreths,

x=-0.59

x=-3.41

Talja [164]

Answer:

e = 300 + .0275c

Step-by-step explanation:

So the earnings = e

Then she earns $300 and a bonus for cosmetics : 2.75%c which is equal to 0.0275 c or .0275c the c for cosmetics.

Thus the answer becomes :

e = $300 + .0275c

Someone please solve this for me!

mezya [45]

Answer:

x = 149

Step-by-step explanation:

The transversal t crosses parallel lines m and n creating a number of angles. Both marked angles are above and to the right of the point of intersection, so they are corresponding angles.

Corresponding angles in this geometry have identical measures:

x° = 149°

x = 149
