Graphing compound inequalities in two variables

MUNAGALA ANAND shared this question 2 years ago

Dear team experts of GeoGebra, Good morning.

I request your valuable guidance to plot the solution set by graphing compound ineqaulities in two variables y<=187-0.85*x and y>=154-0.7*x for 20<=x<=75.

I need only the solution set region of intersection.

Dear experts, when shall I expect the answer?

1

copy and paste in input bar y ≤ 187 - 0.85x ∧ y ≥ 154 - 0.7x ∧ 20 ≤ x ≤ 75

then zoomout

thesimbol is equal to && with keyboard

Dear sir, I tried as you suggested and typed the inequalities manually too but I did not get the required out put. The graph is empty. Is there any other alternative? or you please send the work out from your side.

Dear sir, Now I got it.

Thank you very much for your kind and swift response to my query in this regard.

Dear sir, to get or command for plotting what is the key?

I mean, to get ^ we need to type &&. So, to get v what is to be done?

The OR operator (vee) is done with ||, type two vertical bars.
