Answer:
For Skyhigh : 40 friends
For Jump it up : 90 friends
Step-by-step explanation:
Given that :
Maximum spending = $250
SKY HIGH FEES :
Party set up fee = $50 ; Amount paid per person = $2
JUMP IT UP FEES :
Party set up fee = $70 ; Amount paid per person = $2
THEREFORE, the inequality statement to obtain the number of friends for eack trampoline center goes thus:
Party setup fee + Number of persons * fee per person ≤ maximum spending
SKY HIGH:
50 + 5x ≤ 250
5x ≤ 250 - 50
5x ≤ 200
x ≤ 200/5
x ≤ 40
Hence,
Skyhigh can accommodate 90 friends Given the conditions
JUMP IT UP:
70 + 2x ≤ 250
2x ≤ 250 - 70
2x ≤ 180
x ≤ 180/2
x ≤ 90
Jump it up can accommodate up to 90 friends Given the conditions.
Answer: Choice C
Vertex = (5, -2)
===============================================
Explanation:
Vertex form is 
where the vertex itself is located at (h,k)
As the name implies, we can very quickly pull out the coordinates of the vertex without doing much math at all.
In the case of choice C, we have 
which is the same as 
and we can see that h = 5 and k = -2. Therefore, the vertex is located at (h,k) = (5, -2)
What are we multiplying exactly?
