Based on the given coordinates of the quadrilateral ABCD, the slopes of the lines given at:
- Slope of AB = -7/4
- Slope of BC = 1/7
- Slope of CD = -5/3
- Slope of AD = 1/2
<h3>What are the slopes of the line?</h3>
The slope of AB is:
= (3 - (-4)) / (-4 - 0)
= -7/4
The slope of BC:
= (4 - 3) / (3 - (-4))
= 1/7
The slope of CD:
= (-1 - 4) / (6 - 3)
= -5/3
The slope of AD:
= (-1 - (-4)) / (6 - 0)
= 1/2
The rest of the question is:
The slope of AB ¯ ¯ ¯ ¯ ¯ is , the slope of BC ¯ ¯ ¯ ¯ ¯ is , the slope of CD ¯ ¯ ¯ ¯ ¯ is , and the slope of AD ¯ ¯ ¯ ¯ ¯.

Answer:
dont you just subtract 90-61 to get 29 since a triangle is 90 degrees
Let "a" and "b" represent the numbers of people on teams Alpha and Beta, respectively. The problem statement tells you
a = (1/4)b
b - 6 - 12 = a + 12
The first equation can be rewritten to give an expresion for b:
b = 4a
This can be substituted into the second equation to get
4a -18 = a +12
3a = 30
a = 10
There were originally 10 people on team Alpha.
Answer:
Step-by-step explanation:
AB:
d = sqrt
( (−5−2)^2 + (−2−(−8))^2)
d = sqrt( (−7)^2 + (6)^2 )
d = sqrt(49+36)
d = sqrt(85)
d = 9.219544
BC:
d = sqrt
( (−7−(-5))^2+(3−(−2))^2
)
d = sqrt( (−2)^2 + (5)^2 )
d = sqrt(4+25)
d = sqrt(29)
d = 5.385165
AC:
d = sqrt
( (−7−(2))^2+(3−(−8))^2
)
d = sqrt( (−9)^2 + (11)^2 )
d = sqrt(81+121)
d = sqrt(202)
d = 14.21267
DE:
d = sqrt
( (−11−(-9))^2+(12−7)^2
)
d = sqrt( (−2)^2 + (5)^2 )
d = sqrt(4+25)
d = sqrt(29)
d = 5.385165
EF:
d = sqrt
( (−2−(-11))^2+(1−12)^2
)
d = sqrt( (9)^2 + (-11)^2 )
d = sqrt(81+121)
d = sqrt(202)
d =14.21267
DF:
d = sqrt
( (−2−(-9))^2+(1−7)^2
)
d = sqrt( (7)^2 + (-6)^2 )
d = sqrt(49+36)
d = sqrt(85)
d = 9.219544
Yes, the triangles are congruent because the lengths are the same.
Answer:
3. Walter's sample is not representative. 4. The population is his community service group.
Step-by-step explanation:
3. His sample is not representative because the survey was only on his math class, not the whole entire population. This sample only represents his math class.
4. The population is his community service group that is what class he is surveying 15 members from.
Hope this helped!
