Answer:
yes
Step-by-step explanation:
40. 24+26=50 41. I don't understand that one either what grade are you in?
First ordered pair: (3,-7)
y=2/3x-5
-7=2/3-5
false
Ordered pair #2: (7.5,0)
y=2/3x-5
0=5-5
true
Ordered pair #3: (0,5)
y=2/3x-5
5=0-5
false
Ordered pair #4: (6,1)
y=2/3x-5
1=4-5
false
the answer to this question is the second option
Answer:
F. 8
Step-by-step explanation:
The ratio of the long side to the short side is the same in similar triangles. The long side of triangle BAD is AD, which has length 20-4 = 16.
BD/DE = AD/BD
h/4 = 16/h
h^2 = 64 . . . . . . . multiply by 4h
h = 8 . . . . . . . . . . take the square root (matches selection F)

<em>Comment on this geometry</em>
BD = √(AD·DC) is called the "geometric mean" of the segments AD and DC. This geometry has some other geometric mean relationships as well:
BC = √(AC·DC)
BA = √(AC·AD)
There are 108 degrees in each interior angle of a regular pentagon .
I hope that's help !
