It would still be a circle
Answer: C
Step-by-step explanation:
We are given the information that:
- The airplane is at 50,000 feet
- It descends 2,500 feet in 1 minute
- x = minutes
For ease of solving this question, let's set the number of minutes (x) to 1.
- In one minute, we know the plane will drop to 47,500 feet. (50,000 - 2,500(x))
There are multiple ways to write this equation bu shifting around negative and positive values. Another way to write this equation would be (-2,500(x) + 50,000). That would be choice C.

It works, so our answer is C.
Step-by-step explanation:
-9x+17
When x =-4, then
-9x+17
-9×-4+17

Answer:
Question 11 - B
Question 12 - C
Step-by-step explanation:
11). 4 chairs per table --> B
12). The 24 pack is a better buy (C).
- 12 pack - 0.3333 per can
- 24 pack - 0.3125 per can <-- cheaper
Adults = 9
Children = 2
Let x be the number of adults.
11-x is the number of children.
22x + 15(11-x) = 228
22x + 165 - 15x = 228
22x - 15x = 228 - 165
7x = 63
7x / 7 = 63 / 7
x = 9 number of adults.
11 - x = 11 - 9 = 2 number of children.
To check:
22x + 15(11-x) = 228
22(9) + 15(11-9) = 228
198 + 30 = 228
228 = 228
