A) Have solution for positive x and y
B) Have no solution for positive x and y
C) Have solution for all x
D) Have solution for all y
Correct Answer: A
Solution :
[a] Following figure will be obtained on drawing the graphs of given in equations. From \[3x-y\ge 3,\] \[\Rightarrow \frac{x}{1}+\frac{y}{-3}=1\] From \[4x-y\ge 4,\] \[\Rightarrow \frac{x}{1}+\frac{y}{-4}=1\] Clearly the common region of both is true for positive value of (x, y).You need to login to perform this action.
