A school is planning an event to raise $1,000 for charity. The cost of organizing the event is $200. The tickets are priced at $
Leviafan [203]
Here is how to solve this question.


Since x represents children and y represents adults.

1,000 = (6x+8y) - 200     

6x + 8y = 1,000 + 200


6x + 8y = 1,200  


1,000 = 8y - 200


1,000 + 200 = 8y


1,200 = 8y


1,200/8 = 8y/8


150 = y

 
150 adults need to attend for the organizers to raise the targeted amount.


Happy studying ^-^

Which features describe the graph of
Arisa [49]

Answer:

4. a vertex at (0, 96) is CORRECT

5. the center at (0, 0) is CORRECT

From the given equation,

a = 40

b = 96

(h,k) = (0,0), the center

The vertices are at (0,96) and at (0, -96).

The curves open upward and downward.

c² = a² + b² = 40² + 96² = 10816

c = 104

Therefore the foci are at (0, -104) and (0, 104).

Check the given answers:

1. a focus at (104, 0) is INCORRECT

2. a focus at (0, -96) is INCORRECT

3. a vertex at (-40, 0) is INCORRECT

4. a vertex at (0, 96) is CORRECT

5. the center at (0, 0) is CORRECT
