we have
Convert to vertex form
we know that
the equation of a vertical parabola in vertex form is equal to
where
(h,k) is the vertex
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
the vertex is the point 
therefore
<u>the answer is </u>
The y-value of the vertex is 
Their total cost of their evening is $14.15
Answer:
The slope of the graph is 3/4
Step-by-step explanation:
The correct question is
<span>Ellie made a cube-shaped cardboard box with side-length s. The area of cardboard she used is given by the formula A = 6s2, where s represents the side length of the cube.
Which equation correctly solves the formula for s?
we know that
</span>A = 6s²---------> clear the variable s
s²=A/6------> applying square root both members
s=√(A/6)--------> s=(1/6)*√(6*A)
<span>
the answer is
</span>s=(1/6)*√(6*A)
