If (4x+9y=36) and (8x+18y=72) are graphed, how many distinct lines will be visible?यदि (4x+9y=36) और (8x+18y=72) को ग्राफ किया जाए, तो कितनी अलग रेखाएं दिखाई देंगी?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (1)(1)
The second equation is (2) times the first, so both are the same line. Only (1) distinct line will be visible on the graph.दूसरा समीकरण पहले का (2) गुना है, इसलिए दोनों एक ही रेखा हैं। ग्राफ पर केवल (1) अलग रेखा दिखाई देगी।
