Answer:
The cost of one ticket is $9
Step-by-step explanation:
we have
4x+12=48
where
x represents the cost of a ticket
Solve for x
Subtract 12 both sides
4x=48-12
4x=36
Divide by 4 both sides
x=36/4=9
therefore
The cost of one ticket is $9
Answer: The first one : -2x^2 + 20x - 54
Step-by-step explanation:
y = -2(x-5)^2 - 4
= -2(x^2 - 10x + 25) - 4
= -2x^2 + 20x - 50 - 4
= -2x^2 + 20x - 54
