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++16+8Y

100-36-16=+8Y

48=+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 ☺️
