Answer:
The solution is (-3, -2).
Step-by-step explanation:
Please note that if you simply add these 2 equations together, 9x - 9x = 0, and you are then left with -5y = 10. Thus, y = -2. Subbing -2 for y in the first equation, we get 9x - 8(-2) = -11, or 9x + 16 = -11.
Subtracting 16 from both sides, we get 9x = -27, so that x = -3.
The solution is (-3, -2).
Answer:
- 2 ≤ n < 8
Step-by-step explanation:
The closed circle at - 2 indicates that n can equal - 2
The open circle at 8 indicates that n cannot equal 8
Otherwise n can be all value between - 2 and 8 including - 2, thus
- 2 ≤ n < 8
Angle 1 is 122 degrees bc of vertical angle
Angle 2 is 87 degrees bc of alt ext angle converse
Angle 3 93 degrees
Angle 4 is 58 degrees

The larger the sample size (number of people asked), the more accurate the results generally are, due to the law of large numbers.
