Answer:

x=5, y=(5)/2

Step-by-step explanation:

Using the 30-60-90 triangle rule, we know that the sides follow 1-(/2)-2. The ratio between the side and the rule is 5/2, meaning that we know that y=(5)/2 and x=5.

Is THIS good enough for you?

Answer:

$y=-2\,(x+3)^2-3$

Step-by-step explanation:

Notice that they are asking you to write the equation of the parabola in vertex form, that is using the coordinates of the vertex $(x_v,y_v)$ in the expression:

$y-y_v=a\,(x-x_v)^2\\y=a\,(x-x_v)^2+y_v$

we can start by directly replacing the given vertex coordinates (-3, -3) in the expression, and then using the extra info on the point the parabola goes through in order to find the parameter $a$ :
