Question

find x if distance between points L (x‚ 7 ) and M( 1, 15 ) is 10 ​

Answer 1

Step-by-step explanation:

L(x,7)=(x1, y1)

M(1,15)=(x2,y2)

d(LM)=10

By the distance formula,

d(LM)=√(x2-x1)2 + (y2-y1)2

10 =√(1-x)2 + (15-7)2

10 =√(1-x)2. + (8)2

10=√(1-x)2. + 64

10= (1-x) + 8

10-8 =. 1-x

2. =. 1-x

x =. 1-2

x =. -1.
