Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h. k) are the coordinates of the vertex and a is a multiplier
here (h, k) = (- 6, - 1), thus
y = a(x + 6)² - 1
To find a substitute one of the roots into the equation
Using (- 3, 0), then
0 = a(- 3 +6)² - 1
0 = 9a - 1 ( add 1 to both sides )
1 = 9a ( divide both sides by 9 )
a =
, thus
y =
(x + 6)² - 1 ← in vertex form
Expand factor and simplify
y =
(x² + 12x + 36) - 1 ← distribute
y =
x² +
x + 4 - 1
=
x² +
x + 3 ← in standard form
Based on Molly's willingness to pay for the 8th trip, and the number of trips she can make over the bridge, her willingness to pay for the bridge repair would be<u> $1.00.</u>
<h3>What is Molly's willingness to pay for taxes to fix the bridge?</h3><h3 />
Molly's willingness to pay for trips is equal to the total consumer surplus she gets.
This means that her consumer surplus is $0.50.
With the bridge fixed, she can make 2 more trips than before because she can make 10 trips.
Her willingnesss to pay for the taxes will therefore be equal to her willingness to pay for the remaining trips:
= 0.50 x 2
= $1.00

Answer:
would be A
Step-by-step explanation:
because bisecting means both sides equal the same. so 4x-12 times two is 8x-24. Hope this helps
