Is the point ((1,4)) in the solution region of (x+2y\le 8)?बिंदु ((1,4)) असमानता (x+2y\le 8) के हल क्षेत्र में है या नहीं?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: no because (9\le 8) is falseनहीं क्योंकि (9\le 8) असत्य है
Substituting ((1,4)) gives (1+8=9), which is greater than (8). In point testing, place both coordinates carefully.((1,4)) रखने पर (1+8=9) मिलता है जो (8) से बड़ा है। बिंदु जांच में दोनों निर्देशांक सही जगह रखें।
