Your friend invites you to attend a
professional sports game at an arena
downtown. You'd like to go, but you
need to find the total cost to attend
the game. The total cost equals the
cost of a ticket plus the cost of bus fare
to and from the arena and the cost of
concession food.
Write a formula that will help you determine
your total cost.
Let's let
t = ticket cost
b = cost of bus fare (one way)
f = cost of concession food
= total cost
Enter the correct answer
DOH
DONE
eller!
Your answer should be an equation for

its a

step-by-step explanation:

true

(2,9)

i think thats the answer i checked it on google

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

5x+2x=49

7x=49

x=7. 35 apples
