Answer:
Solution 3 is correct and solutions 1 and 2 are incorrect.
Step-by-step explanation:
It says that the parallelogram is reflected across the x-axis. Think of reflection like a reflection in a mirror. The coordinates are mirrored across the x-axis (or the horizontal plane) and the x- coordinates stay the same but the y coordinates change. When you reflect across the y-axis, the x-coordinates change but the y-coordinates stay the same.

Answer:the number of advance tickets sold is 35
the number of same day tickets sold is 40
Step-by-step explanation:
Let x represent the number of advance tickets sold.
Let y represent the number of same day tickets sold.
For one performance, there were 75 tickets sold in all. This means that
x + y = 75
Advance tickets cost $20 and same-day tickets cost $25. The total amount paid for them was $1700 both tickets. This means that
20x + 25y = 1700 - - - - - - - - - - - 1
Substituting x = 75 - y into equation 1, it becomes
20(75 - y) + 25y = 1700
1500 - 20y + 25y = 1700
- 20y + 25y = 1700 - 1500
5y = 200
y = 200/5 = 40
substituting y = 40 into x = 75 - y, it becomes
x = 75 - 40
x = 35
Answer:
36x - 7
Step-by-step explanation:
Rule: For any triangle, the smallest angle is always opposite the smallest side.
(a similar rule is that the largest angle is opposite the largest side)
We see that AC = 9 is the shortest side. Angle B is opposite this side. Therefore, angle B is the smallest angle. We don't know what angle B is in terms of a number and we don't need to find out.
Answer: choice B) angle B
side note: we could use the law of cosines to actually compute the numeric value of angle B, but that's more work than needed
8.97x6.8=60.996 we multiplyed the numbers together
