1. Selesaikan persamaan kuadratik berikut: \[ y^{2}+5 y-4=2(4 y+3) \]

Solve by the elimination method. \[ \begin{array}{l}2 x=36+3 y \\ 5 x=3-7 y\end{array} \]

Identify the translations of the graph of the parent function \( f(x)=x^{2} \) that result in the graph of \( g(x)=(x+2)^{2}+6 \). right 6 units, down 2 units right 2 units, up 6 units left 2 units, up 6 units left 6 units, up 2 units

a) \( \frac{2 x y-1}{4 x^{3}}-\frac{3 y-x}{6 x^{2}} \);

3. A parabola with equation \( y=3(x-m)(x-2) \) has a vertex with \( x \)-coordinate equal to 7 . What is the \( y \)-coordinate of the vertex of this parabola?

Find a formula for the inverse. \( f(x)=5 x^{3}-8 \)
