Answer: -69q+74
Step by step:
1. Use distributive property.
8⋅10+8(−6q) + 3(−7q − 2)
Multiply 8 • 10 then -6 • 8
80 - 48q + 3(-7q - 2)
2. Use distributive property again.
80 - 48q + 3(-7q - 2)
Multiply -7 • 3 then 3 • -2
80 - 48q -21q - 6
3. Simplify
Subtract 6 from 80 then subtract 21q from -48q.
-69q + 74
8(10 - 6q) + 3(-7q - 2) = -69q + 74

Answer: A.
Step-by-step explanation:
To find mean, average the numbers in the data set by adding them together and dividing by the number of values.
(96 + 77 + 82 + 91 + 89) / 5 = 87.
To find median, take the "middle" value of the data set. To find this, you can sort the numbers in ascending order and remove the same amount of values from each side.
77 / 82 / 89 / 91 / 96, the median is 89.
Therefore, the mean is less than the median.
Answer:
B and C
Step-by-step explanation:
(4, 2 ) → (- 4, 2 )
(- 3, - 1 ) → (3, - 1 )
We can see from both points that the y- coordinate did not change. → B
The x- coordinate of P' is the negative of the x- coordinate of P → C
