Answer:
![y = - 2x + 5](https://tex.z-dn.net/?f=y%20%3D%20%20-%202x%20%2B%205)
Step-by-step explanation:
Simply simplify the equation from what it is to the slope intercept format:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
Answer:
The average final score = 82.58
Step-by-step explanation:
we have given,
Grading Scale 1 has the following weights :-
Tests- 50% , Quiz- 25% , Homework- 15% and Final Exam- 10%
Total % marks obtained in tests =
= 81.33%
Total % marks obtained in quiz =
= 83.66%
Home work score = 90
final exam score = 75
Now, Weight of tests grade = 50% of 81.33 = 40.665
Weight of quiz grade = 25% of 83.66 = 20.915
Weight of homework = 15% of 90 = 13.5
Weight of final exam = 10% of 75 = 7.5
So the average final score = 40.665 + 20.915 + 13.5 + 7.5 = 82.5

14: plug in the points to y1-y2/x1-x2 (equation for slope)
20-13/x-11= 7/3
What value of x makes x-11=3 true?
Add three to each side to get x=14
Answer:
Look below.
Step-by-step explanation:
One property of a cyclic quadrilateral is that the opposite angles are supplementary. Angles ABC and ADC are opposite; therefore, supplementary. We know that angle x is supplementary to angle ABC because they are on the same line. We know that angle y is supplementary to angle ADC because they are on the same line.
ABC + ADC= 180 degrees
ABC + x= 180 degrees
ABC + ADC = ABC + x
- ABC -ABC
ADC= x
ADC+ y= 180 degrees
ADC + ABC= 180 degrees
ADC+y= ADC+ABC
-ADC -ADC
y=ABC
ABC=x ADC=y
ABC + ADC= 180
Property of substitution:
x+y=180
