1. AD ≅ BC, AD║BC, E & F are midpoints of BC, AD . . . . given
2. (1/2)AD ≅ (1/2)BC . . . . multiplicative property of congruence (equality)
3. DF = (1/2)AD, BE = (1/2)BC . . . . definition of midpoint
4. DF ≅ BE . . . . substitution property of congruence
5. BE║DF . . . . segments of parallel lines are parallel

What is the mean?
-9 -9 -3 -6 -7
Answer:
-6.8
Step-by-step explanation:
To find the mean, you add all the numbers together, then divide that number by the amount of numbers there were, so:
-9 + -9 + -3 + -6 + -7 = -34
-34/5 = -6.8
Yoooo, if you gave me brainliest that would be pretty pog. Because as it turns out, only a small percentage of the people I answer actually give me brainliest.

The lines 2x=ky+2 and (k+1)x=6y-3 have same gradient. Find possible values of k
I need the answers ASAP please!
Answer:
k = 3 or k = -4
(Anyone can correct me if I'm wrong)
Step-by-step explanation:
[tex]2x=ky+2\to\ eq1\\(k+1)x=6y-3\to\ eq2\\$Change to this form: $y=mx+c\\ky=2x-2\\y=\frac{2x-2}{k}\\$gradient of eq1: $\frac{2}{k}\\6y=(k+1)x+3\\y=\frac{(k+1)x+3}{6}\\y=\frac{k+1}{6} x+\frac{3}{6}\\y= \frac{k+1}{6} x+\frac{1}{2}\\$gradient of eq1: $\frac{k+1}{6}\\$Since gradient, m, is the same for both lines,$\\\frac{2}{k}=\frac{k+1}{6}\\12=k^{2}+k\\k^{2}+k-12=0\\(k-3)(k+4)=0\\k=3 $ or $ k=-4[/tex]

Who understands how to do this mess?
Answer: 140
Step-by-step explanation:
Angle 4 and A are supplementary meaning they add to 180
Thus you can do 180-40 = 140 to get that angle A = 140.
Since the two lines are parallel, Angle A is congruent to Angle D. Then, since Angle D is opposite Angle 3, we know that that Angle 3 and Angle D are congruent.
The helicopter can travel 75 miles per hour. How many miles per minute can the helicopter travel?
Answer:
4.69 miles per minute
Step-by-step explanation:
75 ÷ 60 (60 minutes in an hour) = 4.6875

In the survey of a community, 55 percent of the people like to listen the radio. 65 percent like to watch the TV. 35 percent like to listen the radio, as well as to watch TV tv.
Answer:
good to know:)
Step-by-step explanation:
use adjacent angles to solve for X
Answer:
69 degrees!
Step-by-step explanation:
Angle MKL = 180 - 146 = 34 (Angles on a straight line add up to 180)
Angle x = 180 - 77- 34 = 69 (Angles in a triangle add up to 180)
Hope this helps! Please mark as brainliest!

What is the equation of the graph below?
А
y = 2(x + 4)2 – 2
B
y = (x – 4)2 – 2
C y = 2(x - 4)2 – 2
D
y = 2(x – 4)2 + 4
Answer:
f(x) = 1(x - 4)^2 - 2
Step-by-step explanation:
Recall that the vertex form of the equation of a parabola is
f(x) = a(x - h)^2 + k, where (h, k) is the vertex and a is a scale factor which stretches or compresses the graph vertically.
Looking carefully at the graph, we see that h must be 4 and k must be -2.
Thus, the equation of this parabola is f(x) = 1(x - 4)^2 - 2 (which matches Answer B)

Find the missing length of the right triangle below
Answer:
C = 13
Step-by-step explanation: According to the pythagorean theorem, which states A² + B² = C². This means that in this equation 5²+12²=x². When we solve this we get 169=x². Since 169 is the perfect square of 13 therefore the answer is 13.

Answer:
Q1Angles forming a linear pair are supplementary and sum to 180°
x + 8x = 180°9x = 180°x = 20°The smaller angle is 20°
Q2A(-2, 10) reflected over x-axis
Rule for such a reflection is:
(x, y) → (x, -y)Point A will map to:
(-2, 10) → (-2, -10)Correct option is D
Q3One point is at the origin and two other points are at the distance m horizontally and vertically from the origin
The last point will have same distance m from the point (m, 0) and (0, m) and this will be point:
(m, 0 + m) = (m, m)What would the answer be?
Answer:
11.35%
Step-by-step explanation:
Add all of the numbers together to get the total amount of people who visited.
Add all the numbers in the teen section to find how many teens visited.
If you put teens over whole it will give you the fraction 86/758
If you divide 86 by 758 you will get 0.11345646438 .
Move the decimal two places to the right and round to get the percent 11.35.
