Question 113

Multiple Choice

Use inequalities to describe R in terms of its vertical and horizontal cross sections. R is the rectangle with vertices (1, -3) , (5, -3) , (5, 2) , (1, 2) .


A) Vertical cross sections: 3x21y5\begin{array} { r } - 3 \leq x \leq 2 \\1 \leq y \leq 5\end{array} Horizontal cross sections: 3y21x5\begin{array} { r } - 3 \leq y \leq 2 \\1 \leq x \leq 5\end{array}


B) Vertical cross sections: 1x53y2\begin{array} { r } 1 \leq x \leq 5 \\- 3 \leq y \leq 2\end{array} Horizontal cross sections: 1y53x2\begin{array} { r } 1 \leq y \leq 5 \\- 3 \leq x \leq 2\end{array}


C) Vertical cross sections: 3x21y5\begin{array} { r } - 3 \leq x \leq 2 \\1 \leq y \leq 5\end{array} Horizontal cross sections: 1y53x2\begin{array} { r } 1 \leq y \leq 5 \\- 3 \leq x \leq 2\end{array}


D) Vertical cross sections: 1x53y2\begin{array} { r } 1 \leq x \leq 5 \\- 3 \leq y \leq 2\end{array} Horizontal cross sections: 3y21x5\begin{array} { r } - 3 \leq y \leq 2 \\1 \leq x \leq 5\end{array}
