Which of the points is NOT one of the vertices (s, t) of the shaded region of the set of inequalities shown below?
Please help

Option D

Step-by-step explanation:

Given: set of inequalities

To find: Points which do not satisfy all the inequalities

Solution:

For point :

So, (15, 0) satisfies all the inequalities

For point :

So, (7.5, 7.5) satisfies all the inequalities

For point (22.5,2.5):

So, (22.5,2.5) satisfies all the inequalities

For point (7.5 ,0):

Put s = 7.5 and t = 0 in

which is false

So,

any options?
