So the maximum height is another word for vertex's y-coordinate. The easiest method to find the vertex is to find the axis of symmetry for the x-coordinate and then plug the axis of symmetry into the equation to solve for y.
Firstly, the equation for the axis of symmetry is , with b = x coefficient and a = x^2 coefficient. Using our equation, we can solve for the axis of symmetry as such:
Now that we have the x-coordinate, plug it into x and solve for y:
In short, the maximum height is 90.75.
Answer:
The equation x = -3y + 4 6y + 2x = 8 has <u>infinite </u>number of<u> </u>solutions.

I completed #1 for you. Each image shows one of the steps.
<em>Follow the exact same steps to complete #2 - #5</em>
#6 asks for a double angle.
Add an extra item to step 3: Draw an arc from vertex through the line
--> then draw another arc from B' to the other side of your line (away from the dot) and label that intersection as B''. Use the measure of the vertex to B'' for the remaining steps.
<em>If you need step-by-step images, you will need to post #6 separately as I can only upload 5 images per question.</em>
Answer:
186.3
To find the answer you have to do inverse operations
9×20.7=186.3
186.3÷20.7=9
