Given the equation below, \( f(x)=-4 x^{2}-7 x-11 \) What is the coordinate point of the vertex? Write your answer with simplified exact numbers, no decimals!

\( \equiv \) (i) Listen A bowl contains blueberries and strawberries. There are a total of 12 berries in the bowl. The ratio of blueberries to strawberries is 1 to 2 . How many of each berry are in the bowl? \( \square \) blueberries strawberries

a \( \quad 2^{3} \cdot 2^{-4} \)

which of the following equations is not a linear function? 1) \( 2 y-3 x=1 \) 2) \( 4 x^{2}+y^{2}=4 x y \) 3) \( y=2 \) 4) \( x=2 \)

\( 3 x-2 y=7 \) (1) \( y+2 y=14 \) (2)

4. Make \( c \) the subject of \( g=\frac{c+3}{4+c}-7 \)
