Answer:
y equals 2/3. u have to do 2/3 ×6 I'm pretty sure
It is 9 because 11 minus 2 is equal to 9.
X+5=9
subtract 5 from each side
x=4
-4 +or- the square root of 1 squared - 4*6*1 all over 2*4
Sure. The function is a parabola. Because the coefficient of the x^2 term is positive, it opens upward. that means that it vertex is a minimum point.
You can verify that the vertex is (0,24). That means that at the point x=0, the height of the bridge is 24m. So if the level water rises below 24 m, the bridge is safe to use.
