Answer:
x=3
Step-by-step explanation:
to find the axis of symmetry of a parabola when the equation is of the form
y = ax^2 +bx+c, we can use
h = -b/2a where h is the line of symmetry
a =1 b = -6 and c =-7
h = -(-6)/ 2*1
h = 6/2 =3
The axis of symmetry is in the x direction
x=3
Answer: The cost per person would be $15.20.
Step-by-step explanation: The price $40 per person when you have 5 people, is 8,8x the price per person. So, if you have 6 people more, you have 8,8x6 less in the price.
8,8 x 6 = 52,80.
44 x 5= 220,00. That was the cost for the limo for 5 people.
It means 220,00 - 52,80 = 167,20 (new price for 11 people)
167,20 ÷ 11 (new price per person) = 15,20.
