Найдите координаты точки пересечения прямых: 14.16 - 1 а) \( y=10 x+30 \) и \( y=-12 x+272 \) 6) \( y=-18 x+25 \) и \( y=15 x+14 \) в) \( y=15 x-21 \) и \( y=7 x-77 \) г) \( y=-7 x-19 \) и \( y=14 x-1 \)

If \( f(x)=2 x+4, g(x)=4 x+8 \), and \( h(x)=4 x^{2}+16 x+16 \), then \( (f+g)(-2)=\square \)

If \( f(x)=x^{4}-x^{3}+x^{2} \) and \( g(x)=-x^{2} \), where \( x \neq 0 \), what is \( (f / g)(x) ? \) \( x^{2}-x+1 \) \( x^{2}+x+1 \) \( -x^{2}+x-1 \) \( -x^{2}-x-1 \)

Use the properties of exponents to simplify the following as much as possible. Assume all bases are positive. Answer only with positive exponents. \( \frac{x^{\frac{1}{4}}}{x^{\frac{3}{4}}}=\square \)

\( \left. \begin{array} { l } { f ( x ) = x ^ { 2 } + 1 \quad g ( x ) = 5 - x } \\ { ( f + g ) ( x ) = } \\ { x ^ { 2 } + x - 4 } \\ { x ^ { 2 } + x + 4 } \\ { x ^ { 2 } - x + 6 } \\ { x ^ { 2 } + x + 6 } \end{array} \right. \)

Graph the following equation and identify the \( y \)-intercept. \( y=x+2 \)
