Ineed with all these, i don't understand.

Step-by-step explanation:

first take an inequality .remove the inequality sign and then draw its graph .

now put the value x=y=0 in the inequality equation to check if its within the graph .if it satisfies the eqn then shade that part of the line which has the origin in it .similarly do for other inequalities.

you will/may get a polygon .it may be bounded or not. now by fundamental theory of lpp, obtain the terminal points

and get the values of x and y. calculate the respective value of fx and find the maximum and minimum of them .the answer will be the respective x and y values.

you can comment me to do a sum of other questions

go and ask your mom to you

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
