Find the value of Y if distance between the points A[4,-4] and B [-2,Y] is 10 * |
|
Answer» ong>Step-by-step EXPLANATION: Distance between A and B= √(-2-4)² + (Y+4)² →10= √(-6)²+(Y+4)² →(10)²=[√(-6)²+(Y+4)²]² →100=36+Y²+16+8Y →100-36-16=Y²+8Y →48=Y²+8Y →Y²+8Y-48=0 →Y²+12Y-4Y-48=0 →Y(Y+12)-4(Y+12)=0 →(Y-4)(Y+12)=0 →Y=4, Y=-12 Here is UR solution.. Hope so it will HELP you dear ☺️ |
