Две прямые при лересечении образуют четыре угла. Вычисли градусные меры этих углов, если сумма двух вертикальных углов равна 150 градусов.

1.3 If \( f(x)=0 \) has roots \( x=\frac{-5 \pm \sqrt{3-12 k^{2}}}{4} \), for which values of \( k \) will the roots be 1.3.1 equal? 1.3.2 Non real

3. Solve the equation for \( y \) : \[ x+\frac{1}{2} y=-1 \]

Given the quadratic function \( f(x)=x^{2}+4 m x+4 m+3 \), where \( m \) is a constant, is always positive when \( r

The functions \( f \) and \( g \) are defined as follows. \[ f(x)=-2 x^{3}-5 \quad g(x)=2 x+4 \] Find \( f(-3) \) and \( g(-5) \). Simplify your answers as much as possible. \( f(-3)=\square \) \( g(-5)=\square \)
