These two should be the points as then 2 points will remain on both sides
Slope
Equation in point slope form
- y+2=3/4(x+6)
- y=3/4x+6-2
- y=3/4x+4
When x=-15
- y=3/4(-15)+4
- y=-45/4+4
- y=(-45+16)/4
- y=--29/4
Just above 7
Answer:
2x-106
Step-by-step explanation:
-7(x+10)+9(x-4)
Expand parentheses:
-7x-70+9x-36
Combine like terms:
2x-106

28 out of 40 of the students passed the test
Answer:
(1/7, 1)
Step-by-step explanation:
By "answer," you probably meant "solution." What is the "solution of the system of linear equations
- 5y = - 5
+ 7x +6y=7
The first eqation can be solved for y: y = 1. Substitute 1 for y in the secon equation. Then 7x + 6(1) = 7, or 7x = 1, or x = 1/7.
The solution to this system is (1/7, 1)
Answers are:
Choice D) more than 102
Choice E) between 90 and 102 messages
Choice F) less than 78
So there are three answers here
The reason for choice D is that 25% of the values are above Q3 (third quartile) which is 102 in this case. Take 25% of 100 to get 25. So there are 25 people who send more than 102 messages
The reason for choice E is that 25% of the data is between the median and Q3.
The reason for choice F is similar to choice D. Twenty five percent of the data values are smaller than Q1 (first quartile) which is 78.
