Vertical angles are equal, so
.. 3x +8 = 5x -20
.. 28 = 2x . . . . . . . . add 20-3x
.. 14 = x . . . . . . . . . . divide by 2
Each of the vertical angles is 3*14 +8 = 50°, so the supplementary one is 130°.
.. 5*14 +4y = 130
.. 4y = 60 . . . . . . . . subtract 70
.. y = 15 . . . . . . . . . . divide by 4
The values of interest are
.. x = 14
.. y = 15
The slope is 2. slope is change in the y values divided by change in x values
Answer:
Lower quartile 3, median 5, Upper quartile 7
Step-by-step explanation:
First divide the data in half 1 3 4 and 6 7 7
The median is the middle between 4 and 6, so it is 5.
The lower quartile is the median in the lower half, 3
The upper quartile is the median in the upper half, 7
Answer:
and 
.

Equation:
Solution:
Set factors equal to zero,that is:
Solving for equation 1:
Solving for equation 2:
Hence,the solutions to the quadratic equation in factored form is and .
Good luck on your assignment!
Add 8 to both sides
2x = 28
Divide 2 to both sides
Solution: x = 14
